According to Rahman, Tamin and Kurdi [5], the highest stress point can be identified for the components by performing stress analysis, which is essential for predicting the life of fatigue life of components. In this research, finite element analysis of the grain trailer body is carried out. In static structural analysis performed on the trailer, static forces created by the trailer body and cargo are applied to the chassis. The development of analysis software and its integration into computer analysis now makes it possible to constrain the model with boundary conditions resembling the physical situation in which it is constrained. The arrow is validated using the analytical formula. As the highest stress point is the starting point for fatigue failure. According to Kassahun [6], the responses of vehicle structural components to static and dynamic loads are very important to produce good quality vehicles with longer service life, higher strength, low resistance. weight and low cost. In this research, this is achieved by studying the structural response of the trailer body, changing the axle placement distribution to see its effect on the trailer towing eye loading in terms of stresses, deformations and deflections. Analysis of key structural components of the trailer chassis, which are affected by high values ​​of stress and strain due to static loading conditions, is identified. Wang and Rauch [7] conducted research on fatigue analysis and design optimization of a trailer hitch using the finite method. element method via Ansys software. The study involved testing the trailer hitch to comply with legal legislation and customer specifications. The failure locations were identified in the middle of the article...... its study, such that the manufacturing cost could be reduced without compromising the fatigue life. FEA and experimental fatigue tests were carried out to study the static and fatigue behavior of the connections. FEA analyzed the effect of weld parameters and local geometry at the cracking zone on the stress gradient and stress concentration. Twelve specimens of the three designs were experimentally tested for fatigue resistance. Harris and Naworocki [12] The finite element method has become an important tool for analyzing vehicle structures and has proven extremely valuable to the heavy vehicle industry. Finite element analysis was used. and has proven to be a very valuable verification tool in various aspects of heavy vehicle design by Karaoglu and Kuraly [9] and Hoberg [13] to successfully reduce the curb mass of the heavy-duty truck industry.
