FEM Analysis and optimization of middle class truck chassis ✍️ In the critical parts of the front chassis of a middle class truck, we have determined the cause of the possible component failure and, proposed the optimized solutions using FEM.For this purpose, based on the geometric 3D model provided by customer and the defined load variants, we create an FE model in which the component-related behavior of the front chassis can be determined. This FE model is used to calibrate the design variations such as the front chassis geometry, strength and life time.
