Exponential tracking control of an electro-pneumatic servo motor
(Strojniski Vestnik/Journal of Mechanical Engineering, 2008)
According to the fundamental importance of the tracking theory on technical systems, the main goal of this paper is a further development of the theory and the application of the tracking, especially to the practical ...
Safe Operation of Welded Structure with Cracks at Elevated Temperature
(Strojniski Vestnik/Journal of Mechanical Engineering, 2008)
The fatigue crack growth rate parameters and conditions for abrupt fracture of thick joint in steel at room and operating temperature were analysed. Fatigue cracks generated from sharp weld defects are initial cracks that ...
Optimization of the Unloading Bridge Working Cycle
(Strojniski Vestnik/Journal of Mechanical Engineering, 2009)
This paper presents one of the possible ways of optimization of unloading bridge working cycle i.e. minimization of: energy consumption, material dissipation during the grab discharging, rope incline angle etc. Optimization ...
Improved solution approach for aerodynamics loads of helicopter rotor blade in forward flight
(Strojniski Vestnik/Journal of Mechanical Engineering, 2008)
This paper presents the numerical model developed for rotor blade aerodynamics loads calculation. The model is unsteady and fully three-dimensional. Helicopter blade is assumed to be rigid, and its motion during rotation ...
Analysis of the Sailplane Final Approaches Performed by Cosine-Law Speed Variations
(Strojniski Vestnik/Journal of Mechanical Engineering, 2010)
High lift-to-drag ratios of the contemporary sailplanes make them the most energy efficient flying vehicles. On the other hand, this capability may become their serious disadvantage during the landing, if their aerodynamic ...
The Possibility for FMEA Method Improvement and Its Implementation into Bus Life Cycle
(Strojniski Vestnik/Journal of Mechanical Engineering, 2010)
This paper shows the way FMEA method (Failure Modes and Effects Analysis), which is widely used in motor vehicles industry, can be improved and later used during certain stages of vehicle life cycle. This is illustrated ...
Determination of a Light Helicopter Flight Performance at the Preliminary Design Stage
(Strojniski Vestnik/Journal of Mechanical Engineering, 2010)
Promising solutions for the problem of the extensively time-consuming modern urban transportation has been found in the use of light and very light helicopters. This paper presents a part of the preliminary design methodology, ...

(Strojniski Vestnik/Journal of Mechanical Engineering, 2010)
According to the fundamental importance of the tracking theory on technical systems, the main goal of this paper is further development of the theory and the application of tracking, especially on the practical tracking ...
Investigations of combustion process in stove fired on biomass
(Assoc. of Mechanical Eng. and Technicians of Slovenia, 2005)
The aim of the investigation was to make some reconstructions on the existing stove used for cooking and baking and to obtain the combined cooker-boiler which will fulfill the demands of European standard EN 12815. ...
Dynamic Response of Mobile Elevating Work Platform under Wind Excitation
(Strojniski Vestnik/Journal of Mechanical Engineering, 2009)
This paper deals with the possibility of aerodynamic instability occurrence in the mobile elevating work platform (MEWP) structure. The vibrations of the structure excited by the von Karman street and the movement induced ...
