ANALYSIS OF THE CONTRIBUTION OF PROTECTIVE BELLOWS ON THE STABILITY OF ALUMINUM FRAMES USED IN PIVOTING JOINT
Апстракт
Numerical analysis of protective bellows attached to aluminum frames of pivoting joints is presented in this
research. Five aluminum frames connected by protective bellows are attached to the circular rod and have
been extracted from the original geometry of passenger bridge used on ocean cruisers. It was assumed that
the circular rod was fixed since the main emphasis in the analysis was on the displacements and stresses of
aluminium frames, not rods. The main load considered in the analysis was a force of 2,500 N (simulating the
mass of 250 kg) acting perpendicularly to three middle frames. Three frames were loaded since it had been
estimated that an average person can apply pressure (with his/her body) on a maximum of three frames at
once. The mass of 250 kg was used in calculations to ensure the value of safety factor =2.5. Since no data
were available about the type of contact between the rod and ends of frames, two approaches were used in
the analysis: firstly, contact w...as considered to be sliding without friction, and secondly contact was considered
to be sliding with friction with the value of friction coefficient =0.2. Values of displacements and stresses
obtained using finite element analyses (FEA) for both approaches and both positions of frames (firm 0 and
max. angle45) are shown and discussed.
