Optimization of Leaf-spring Suspension Parameters Based on Ride Comfort Simulation

Multi-body dynamic model of a vehicle with leaf spring was established,and roughness of the the road surface was reconstructed with road surface spectrum.The total root mean square acceleration was taken as the evaluation index for optimization of the ride comfort of the vehicle,and the parameters of the suspension,stiffness and damping coefficient,were optimized.Roadway test was performed to verify the presented method,which provided references for the design of suspension under the consideration of ride conmfort optimization of the vehicle.
