Optimalizace nosného rámu malého vozidla

Abstract

This thesis deals with the analysis and optimization of the frame structure of a small vehicle, using the finite element method (FEM). The aim of the thesis is to evaluate the existing structural solution, namely torsional stiffness, natural frequencies and mechanical resistance to loading, and to propose an optimized solution, with emphasis on maintaining the minimum weight without compromising the resulting stiffness and durability of the frame. The thesis includes a theoretical analysis of the frame structures, a description of the loads acting on the frame during normal operation and a review of the computational methods used in its design and analysis. The practical part is divided into two parts, which include the analysis of the original frame and the optimized frame. These parts are devoted to the creation of FEM models, their analysis of static and dynamic loads and the comparison of the results with each other.
