This paper focuses on using HyperMesh software to simulate and evaluate the structural strength of the 2012 Toyota Yaris, utilizing the OptiStruct solver with support from LS-Dyna for FEM modeling. The objective is to research and improve the structural design of this vehicle model and similar sedan types. The simulation process will yield strength assessment results through verification scenarios such as bending, torsion, cornering, and uphill driving under the influence of gravitational forces. According to the result, there are 2 cases among 4 tests that are used to test the structural strength of the chassis did not meet the allowable limit of the overall yield strength and displacement of components. Which is the test of torsional strength and the cornering situation test. From there, the solution that was chosen to solve the lack of strength in the 2 tests is replacing the initial material at the specific components with a stronger material to increase the overall strength and integrity.
