Analysis of the Bus Chassis with Finite Element Method through MATLAB and Abaqus Software

It is possible to analyze trusses and frames manually and using relations to the extent that the geometric conditions and loading of the problem are simple to a great extent and the number of elements and members of the truss or frame does not exceed a small number. But in real problems, loading and dimensions are complex and the number of elements is large. For this reason, the solution of such problems is done by numerical solution and with the help of the theory of finite element methods. In this research, the stress and displacement of a frame, which is a schematic of one of the chassis walls of a bus, where the driving forces are installed, is analyzed. To accurately solve the problem, coding in MATLAB has been used (in order to reduce errors and increase speed). Also, problem modeling has been done in Abaqus software. Finally, the results of MATLAB code and Abaqus analytical solution confirm each other well.
