Abstract

Vehicle chassis structure design is an important part of vehicle design. In this paper, the structure design of vehicle chassis is systematically studied from three aspects: theory and method, design and analysis, optimization algorithm and simulation. In terms of load analysis and chassis structure analysis, an effective analysis method is proposed. A reasonable modeling method is proposed in terms of the establishment of constraints and ob jective functions. In the selection of optimization algorithm and optimization strategy, two optimization methods, evolutionary algorithm and simulation, are adopted. Through the selection of chassis structure design parameters and the definition of variables, several groups of chassis structure design schemes are generated and evaluated. Through performance analysis and verification, the superiority of the selected scheme is verified. Finally, the optimization algorithm and simulation method of chassis structure based on evolutionary algorithm and simulation are proposed, which provides an effective technical means for vehicle chassis structure design.
