Development of electric vehicle (EV)-bus chassis with reverse engineering method using static analysis

This research aims to simulate structural steel 400 (SS400) material as an alternative for the electric bus's chassis structure. The kind of is low carbon steel. SS400 produced from one largest mills in Indonesia, considered a local material. used increase total domestic content cars Indonesia could be improved. Generally, reverse engineering method R260 ladder frame type vehicles. However, this fulfill vehicle (EV)-bus with method. After model was successfully created using finite element software, statics analysis carried out von Mises stress and simulation results' deflection. meshing process structure such way assume global contact. Loading evenly over two main beam frames totaling 14,200 kg. elasticity modulus tensile strength values are 190 GPa 480 MPa. Furthermore, support placed mounting position front rear wheel leaf springs at front, overhang, wheelbase distance 2,380 mm, 3,290 6,000 mm. resulting approach two-overhang model. results showed that obtained maximum value 75.8 MPa, deflection 2.568 lowest safety factor 3.2. Meanwhile, through theoretical calculations, occurred 72.33 MPa 2.594. There no significant difference between
