| Abstract: | In order to accurately predict the acceleration performance of a tracked vehicle, the process of its starting acceleration was simulated by using an iterative correction algorithm. By identifying multiple discrete states in the process and by switching these states, the rotational speeds and the torques of the transmission components, and the time histories in speeds, accelerations and displacements of the vehicle are obtained. The simulation results tallies with the experimental data, showing that the above simulation is reasonable and effective by means of the discrete state switching method. |
