Study on the Ride Comfort of the Rhombic Car

Abstract

In order to study the dynamics of rhombic car performance, the mathematical model of the ride comfort was deduced. Through the establishment of fifteen degrees of freedom simulation model, the dynamic performance of rhombic car was analyzed under different speed and different road surface. The mathematical model's correctness of the ride comfort was verified according to testing the prototype of the rhombic car, the error was about 7% by comparing the experimental and simulation data, and the overall trend is consistent. So, the mathematical model was correct. The fifteen degrees of freedom simulation model can used to the further study on dynamics of rhombic car performance, which has great significance in engineering.
