| Abstract: | Based on a seven DOF mathematic model of a mini car, some function expressions in relation to centroid acceleration, relatively dynamic load, dynamic spring deflection and root mean square value of acceleration were derived according to the energy method. The corresponding simulation programs were written by means of Matlab software, and some tests were carried out in a proving ground. The test findings indicate that the simulation results tally with the testing curves, which proves the correctness of the simulation analysis and its referential value for the future development. |
