| Abstract: | According to appraisal method of automotive ride comfort, a random input dynamic simulation program for five DOF's vehicle model is developed, using Matlab toolbox. Through simulation, the maximum root mean square value of weighted acceleration and the root mean square value of total weighted acceleration of given points are obtained directly. The simulation results coincide well with that of random input running test. So the method is proved to be correct, which can be applied to the design of vehicle suspension system parameter and the assessment of vehicle ride comfort. |
