摘　　要：针对双车体铰接履带车非结构地形的通过要求,提出一种可实现前后车体俯仰、侧翻、转向的铰接机构。该机构与其他同类铰接机构最大的区别在于前后车体的俯仰运动相互独立,提高整车在地面上的稳定性。在动力学分析的基础上,讨论了铰接履带车的越壕能力。利用多体动力学仿真软件建立了虚拟样机,通过仿真对比了单体履带车和文中所提机构连接的铰接双体履带车辆的越壕能力,并对越壕过程中的履带张紧力、驱动力矩和质心变化等参数进行了对比分析。By considering the crossing requirements of uneven terrain for articulated tracked vehicles,an articulated mechanism to realize the pitching,rolling and turning between front vehicle unit and rear one was proposed.The most distinct difference between this mechanism and the other similar articulated mechanisms is the pitching motion between the front and the rear units is independent,which improves the stability of the vehicle on the ground.Based on dynamics analysis,trench crossing capability of articulated tracked vehicles was discussed.The multi-body dynamics analysis software is used to model a virtual prototype,the simulation was done to compare the trench crossing capabilities of ordinary tracked vehicles with the articulated tracked vehicles in this paper.The comparative analysis of the parameters related trench crossing,such as bushing tension,driving torque,center of mass motion,has been carried at the end.
