Abstract: Vehicle riding comfort is an important index of vehicle chassis performance.Seven-dof vehicle model and road input model are established, a calculation platform for vehicle riding comfort is developed with MATLAB. Based on the development of a light truck, the optimization design of the riding comfort index is completed with this calculation platform, and the calculation result is compared with experimental data and analyzed. The models and results of simulation are verified to be efficient and can be used for chassis development.
