| Abstract: | In this paper, combined with the problem faced by the development of one Extended-Range Electric SUV,through theoretical analysis, suspension K&C analysis, vehicle handling analysis, rear suspension kinematic multi-objective optimization and so on, the K characteristics of rear suspension are optimized, the solution is put forward, on the condition of ensuring the chassis parts reuse. The design prototype car is made. Based on the subjective evaluation conclusions of the prototype car, the chassis performance problems are well solved. This is a good foundation for chassis performance improvement next step. |
