AB  - Nitinol is a material widely known because of its super-elasticity characteristic which is important in the cyclic load area. Atherosclerosis is a disease of the modern age that involves blood vessels narrowing. If this condition is not properly treated, the consequences can be serious. Therefore, it is of great importance to study the optimal characteristics of the stent and the hemodynamic condition in the blood vessels. Self-expanding nitinol stents have been often used to treat arterial narrowing. This paper will analyze the influence of the ratio between the stent diameter and the blood vessel diameter and their correlation with radial forces in the case of atherosclerotic plaque or fibrous cap. Also, this paper will analyze recommended stent thickness to ensure satisfactory deformations at the end of the fatigue cycle.

AB  - Tankozide cilindrične strukture imaju veoma visoku primenu u industriji. Pošto su obično opterećene na aksijalni pritisak, najčešći uzrok njihovog otkaza je pojava izvijanja. U ovom članku se prikazuje numerička analiza izvijanja tankozide cilindrične strukture izrađene od legure aluminijuma sa imperfekcijom u vidu udubljenja na sredini strukture i eksperimentalna verifikacija rezultata dobijenih tom analizom. Numerička analiza je odrađena pomoću softvera ANSYS 16.2, a eksperimentalna ispitivanja pomoću hidraulične prese Armavir, PSU-50, na kojoj je uzorak podvrgnut aksijalnom pritisku čiji se intenzitet postepeno povećavao do pojave izvijanja. Poređenjem rezultata eksperimenta uočeno je značajno smanjenje vrednosti kritičnog napona na izvijanje između epruveta bez imperfekcije i epruveta sa imperfekcijom od 2 mm, dok su vrednosti kritičnog napona za epruvete sa imperfekcijama od 2 mm i 4 mm približne.
AB  - Thin-walled cylindrical shells are commonly used in numerous branches of industry. Since they are subjected to axial load, the most common cause of their failure is buckling. This paper provides numerical analysis and experimental verification of the buckling of the thin-walled aluminium alloy cylindrical shell with special regard to the influence of dent, positioned in the middle of the shell. Numerical simulation was performed using ANSYS 16.2, and experimental verification was performed by means of hydraulic press Armavir, PSU-50, which was used to subject the specimen to the increasing axial load until the occurrence of buckling. Comparing the results it was concluded that there is significant decrease of the buckling resistance if compared the values of the specimen with no dent, and the specimen with 2 mm deep dent. On the contrary, resistance of the 2 mm and 4 mm dented specimen is quite similar. Position and shape of the deformations occurred due to buckling are matching if experimental and numerical results are compared.

AB  - This paper presents experimental determination effectiveness of active vibration control system depending on
sensor location. The active structure consists of an composite beam as the host structure, strain gages as the sensors
and piezoceramic patch as the actuation element. The Wheatstone bridge, sensor platform, is used to measure the strain
of mechanical system which represents the control signal in system. The active vibration control system is controlled by
PID control strategy. Control algorithm was implemented on the PIC32MX440F256H microcontroller platform. For
the experiment two locations for sensor platform are chosen. In order to determine the influence of piezoelectric
ceramic actuator work on sensor (control) signal the tip deflection of beam is measured by high speed camera. The
active vibration control system effectiveness of both sensor and actuator positions are considered. Experimental results
demonstrate that the presented control method is effective for both locations but the stability of the system can be
violated.

AB  - This article investigates active vibration suppression of a flexible beam with a low dominant frequency using strain gages sensor and dual layer piezoelectric actuators. The strain gages sensor and piezoelectric actuators are in patch form and are surface-bonded to the cantilevered end of the composite beam. The feedback PID control algorithm is adopted for active vibration control of the composite beam . The effects of different gains in proportional, integral and derivative control are considered experimentally. Experiments are conducted to verify the effectiveness of the vibration suppression and to compare the damping effect with different adjustment of PID gains. With given experimental results are determined the best effectiveness of active structure.

AB  - Piezoelectric actuators and sensors have a wide range of application in the active vibration control of flexible
structures. Control performances of the smart structures depend on the size and position of piezoelectric actuators and
sensors on a smart structure. This paper deals with the optimization of sizing, location and orientation of piezoelectric
actuators-sensors pairs on thin-walled composite plate. Optimization criteria are based on eigenvalues of the
controllability Grammian matrix. The optimization problem is formulated by integration of finite element method based
on the third-order shear deformation theory and the particle swarm optimization method. Numerical examples are
provided for symmetric cross ply cantilever quadratic composite laminates. Linear quadratic regulator has been
implemented for active vibration control of the composite plates with the optimized piezoelectric actuator-sensor pairs
in order to show the efficiency of presented optimization method.

AB  - Improving aircraft pilot comfort requires continuous work in decreasing vibrations in the seat. In order to determine the suitability and potential of cockpit floor - seat connections we conducted an experiment where measurements were taken and seat vibration analysis conducted. Vibrations parameters were measured for maximum engine and propeller speed. This analysis indicates that passive vibrations damping or cockpit floor - seat connections functionality depends on flights profile and vibrations frequency. The connection in question was behaving like a vibration multiplier on the 3rd and 4th harmonic as well as on the 3,5 sub-harmonic in individual flight modes on basic propeller rotation frequency, however, it behaved as a vibration silencer on all other frequencies. Analysis of the experimental data has shown that it would be justified to start improving the self adaptive unit for active vibration reduction for pilot seats.

AB  - Piezoelectric actuators are widely used in structural systems for active vibration
control with the aim to enhance the performance of systems. In order to improve the
dynamic characteristics of active system, it is necessary to know the changes in modal
parameters of systems after embedding of piezoelectric actuators. The effectiveness of
chosen piezoelectric actuator on real system is a very important characteristic in order to
determine capabilities of vibrations suppression. This paper presents two experimental
investigations whose aim is to define the input and output parameters for development of
active vibration control system. In the first experiment modal parameters of the thin
rectangular plate with embedding of piezoelectric actuator is determined. The dynamic
behavior of the thin rectangular plate is identified by using the strain gages (full bridge)
sensor. The second experiment is performed aiming to identify the voltage limits of the
controller’s output for the first three natural frequencies of the rectangular plate. The
determined parameters (natural frequencies and control voltage limits of piezoelectric
actuator) represent boundaries which must be satisfied in the process of development of the
active vibration control system.

AB  - This paper presents experimental verification of the active vibration control of a smart cantilever composite beam using a PID controller. In order to prevent negative occurrences in the derivative and integral terms in a PID controller, first-order low-pass filters are implemented in the derivative action and in the feedback of the integral action. The proposed application setup consists of a composite cantilever beam with a fiber-reinforced piezoelectric actuator and strain gage sensors. The beam is modeled using a finite element method based on third-order shear deformation theory. The experiment considers vibration control under periodic excitation and an initial static deflection. A control algorithm was implemented on a PIC32MX440F256H microcontroller. Experimental results corresponding to the proposed PID controller are compared with corresponding results using proportional (P) control, proportional-integral (PI) control and proportional-derivative (PD) control. Experimental results indicate that the proposed PID controller provides 8.93% more damping compared to a PD controller, 14.41% more damping compared to a PI controller and 19.04% more damping compared to a P controller in the case of vibration under periodic excitation. In the case of free vibration control, the proposed PID controller shows better performance (settling time 1.2 s) compared to the PD controller (settling time 1.5 s) and PI controller (settling time 2.5 s).

abstract = "This paper presents experimental verification of the active vibration control of a smart cantilever composite beam using a PID controller. In order to prevent negative occurrences in the derivative and integral terms in a PID controller, first-order low-pass filters are implemented in the derivative action and in the feedback of the integral action. The proposed application setup consists of a composite cantilever beam with a fiber-reinforced piezoelectric actuator and strain gage sensors. The beam is modeled using a finite element method based on third-order shear deformation theory. The experiment considers vibration control under periodic excitation and an initial static deflection. A control algorithm was implemented on a PIC32MX440F256H microcontroller. Experimental results corresponding to the proposed PID controller are compared with corresponding results using proportional (P) control, proportional-integral (PI) control and proportional-derivative (PD) control. Experimental results indicate that the proposed PID controller provides 8.93% more damping compared to a PD controller, 14.41% more damping compared to a PI controller and 19.04% more damping compared to a P controller in the case of vibration under periodic excitation. In the case of free vibration control, the proposed PID controller shows better performance (settling time 1.2 s) compared to the PD controller (settling time 1.5 s) and PI controller (settling time 2.5 s).",

AB  - U radu je prezentovan praktičan primer merenja i analize vibracija na helikopterskoj strukturi sa ciljem da se otkriju potencijalna oštećenja radnih elemenata. Sveobuhvatna metodologija merenja vibracija je predstavljena u ovom članku i sprovedena sa ciljem da se utvrdi ispravan rad rotirajućih komponenata. Poseban osvrt je dat na analizi uzdužnih i vertikalnih vibracija trupa helikoptera u frekventnom domenu za različite profile leta. Merenje i analiza vibracija na određenim lokacijama helikopterske strukture, rezultiralo je blagovremenim tehničkim pregledom odgovarajuće komponente i otkrivanjem njenog površinskog oštećenja. Praktična upotreba predložene metodologije merenja i analize je moguće implementirati na više vrsta letelica u cilju produženja životnog veka.
AB  - A practical example of the measurement and analysis of vibrations on helicopter structures in order to detect defects on operating elements is presented in this paper. A comprehensive methodology of vibration testing is presented in this article and implemented in order to determine the correct operation of rotating components. A particular attention is given to the analysis of longitudinal and vertical vibrations on the helicopter fuselage in the frequency domain for different flight profiles. The vibration measurement and analysis on specific locations on a helicopter structure resulted in a timely technical review of a relevant component and a disclosure of the damage on its surface. The proposed methodology of measurement and analysis can be implemented on different types of aircraft in order to extend their life expectancy. .
