| Abstract: | The eight DOF car ride dynamics model is established.Lagrange equation of eight DOF car model is also derived.A simulation model of car ride is established by using simulation software Matlab/Simulink.At different speeds the vertical acceleration signal of the driver's seat,co-pilot seat and left rear seat are simulated.Simulation results in frequency domain are obtained,and compared with experimental results. |
