Simulation and experimental research on vehicle ride comfort and suspension parameters optimisation

With the development of vehicle technology and the improvement of living standards, people's ride comfort requirements for vehicle are also increasing. Especially for commercial passenger vehicles, the ride comfort is related to physical and mental health of passengers. Since the suspension is a major chassis system that affects the ride comfort of vehicle, so for how to make the vehicle to maintain good ride in a variety of driving conditions, the design and improvement of suspension are essential. The research content of this paper is simulating and optimizing the suspension parameters based on kinetic model of vehicle. First, a kinetic model of vehicle for minibus system is established. Then, test verification is carried out for the ride comfort of vehicle model. The results show that the established vehicle model can be used for simulation and optimization of front and rear suspension systems through the application of genetic algorithm.
