Structural Performance Analysis of Electric Vehicle Strut Bar under Static Loading Condition Using Finite Element Method

抄録

Electric vehicles (EVs) revolutionized the automotive industry, necessitating revolutionary structural integrity and performance solutions. In this Paper, A strut bar is required in electric vehicles to improve both driving stability and safety. This study investigated the crucial function of strut bars in improving the structural behaviour of EVs, where there was a scarcity of data on the relationship between the geometry of the EV strut bar and its structural performance under static loading. The data was required as a reference for improving the design of similar components. This had the potential to impair driving dynamics and safety. The purpose of this research was to investigate the structural performance of strut bars in EVs under static loading circumstances. Begin optimising the strut bar design by identifying the load using vector analysis, then define the geometrical specifications based on the BMW i3 baseline component. After that, choose AISI 1018 as the material, create a 3D geometrical model in CATIA V5, and then perform FEA static analysis in the same software to evaluate structural performance. This provided a thorough understanding of their structural behaviour, boundary condition and magnitude load distribution. The maximum von Mises stress, denoted as σmax, is 138 MPa, with a corresponding maximum deformation, ∂max, of 0.531 mm. The maximum stress location is determined, and the safety factor is calculated as 370/138, yielding a value of 2.68. The study's findings can be used as a useful benchmark for establishing safe load limits for electric vehicles. The research validates the structural performances of the EV strut bar. This knowledge enables engineers to create EV strut bar designs that are unique in terms of shape and positioning within the vehicle. The findings serve as a critical benchmark for determining safe load limits for electric vehicles.
