Abstract:

Under understanding the necessity of the weight reduction without decrease in strength properties of a construction part the authors have tried to declare the methodology of the parts’ construction on the example of the brake calliper piston. Taking commonly used high strength aluminium wrought alloy of the 6xxx-serie the behaviour of the piston under plain compression load was investigated separately for elastic and plastic deformation. After that it was compared with the results for carbon steel C10. Under definition of the maximal allowed parameter’s value for elastic and minimal allowed parameter’s value for plastic deformations, represented by factor of safety (FoS) and yield stress respectively, the sensitivity maps of the proposed piston constructions were calculated. Opposite to the total topology optimization the outer geometry of the original piston was unchanged. The results of the study have shown that the changing of the inner geometry can be done in a certain range without any significant strength decrease of the construction part but not arbitrary.
