摘　　要：高速履带车辆具有良好的通过性,车辆在起伏路面或者坏路面上行驶时,平顺性会急剧下降,影响行进间射击命中率和乘员舒适性。油气悬挂与传统的扭杆弹簧悬挂相比,具有良好的非线性特性,可以改善车辆平顺性。基于拉格朗日动力学建立了高速履带车辆动力学模型,并且在多体动力学软件Recur Dyn中建立了整车模型,对高速履带车辆油气悬挂平顺性进行了仿真分析。High-speed tracked vehicle possesses the excellent passing ability,but the ride comfort and round hitting probability deteriorate rapidly when the vehicle is running on a fluctuant road.Hydro-pneumatic suspension owns better nolinear characters compared with traditional torsion rod suspension,which can improve vehicle’s ride comfort.High-speed tracked vehicle dynamical model is established based on Lagrangian mechanics.A simulation model is built on RecurDyn,and the ride comfort is simulated and analyzed.
