| Abstract The vehicle chassis structure is the foundation on which the different parts of the car are mounted and it is a combination of longitudinal and transverse elements. When the vehicle moves along the road, its chassis begins to vibrate under the effect of various dynamic forces, which may cause the resonance phenomenon in the chassis and suffer large fluctuations, resulting in excessive bending and failure of the chassis. In this research, the aim is to analyze the limited components of the chassis structure of a single-passenger desert Vehicle under static and dynamic loads. First, the chassis structure of a desert single-seater vehicle was modeled by Solid works 2016 software, and then it was transferred to Abaqus CAE 2108 finite element software and the loads applied to the chassis structure, both static and dynamic, which include the weight of the chassis components, braking and turning were determined and the model was analyzed under specific boundary conditions and under the influence of the above loads. The obtained results indicated that the safety factor coefficient in the states of static bending and twisting, braking and turning with maximum acceleration is 1, 0.97, 0.93 and 0.86 respectively, which indicates a relative safety factor coefficient. The bottom is especially in turning modes. Also, the maximum stress on the chassis is higher than the durability limit stress; therefore, it was concluded that the chassis has a limited life and it is necessary to strengthen and optimize the chassis. |
