悬架变动对水陆两栖车性能的影响

为了提高我国两栖车的航速,采用收起车轮的方法实现减阻提速。通过降低悬架系统,提高横臂摆动的范围来增大车轮收起的幅度,达到最大程度降低水对车轮的阻力的目的。利用AD-AMS对悬架和整车建模仿真,分析悬架降低前后性能。对比仿真结果可知:悬架系统降低后的两栖车抗侧倾和抗制动点头、加速抬头的能力下降,行驶平顺性有所提高。

Effects of Suspension Change on Performance of Amphibious Vehicle

For the purpose of increasing the speed of an amphibious vehicle,its wheels are retracted and the resistance is reduced.The scope of retraction is increased by lowering down its suspension and expanding the pendular scope of its horizontal arms so as to reduce the resistance effect of water on its wheels as greatly as possible.We use the ADAMS software to model and simulate the vehicle and its suspension and analyze the performance of the vehicle before and after the lowering of its suspension.The simulation results show that after the lowering of its suspension,the vehicle′s capability of anti-leaning to its side,anti-rolling and anti-pitching decreases,and its riding smoothness increases.
