Návrh tvarově optimalizovaného podélníku pro lehký tandemový jednonápravový přívěs

Abstract

This bachelor thesis deals with the design of different shapes of longitudinal members for the TVK10M trailer and their strength analysis. The aim is to verify the existing solutions and propose alternatives with regard to weight and strength. The calculations have been carried out using the finite element method in Simcenter 3D. Five designs with different geometries and wall thicknesses are presented, for which the stress and deflection variation was monitored. The results show that a significant weight reduction can be achieved without compromising the mechanical properties. The best results are achieved by the "accordion"variant with a weight reduction of 44,26 % compared to the original design.
