ATV的履带车辆动态特性研究

摘要

The coupling effect of ground, track and wheels of track vehicles was studied. The external factors influencing the dynamic characteristics of the track vehicles were analyzed. Taking a real track-vehicle as an example, the simulation model for dynamic performance analysis was established by means of ATV software. The dynamic characteristics of the track vehicle were studied under the condition of different ground topography, vehicle speed and initial track’s tension. This work has provided a basis for track-vehicle design and optimization.%针对履带车辆的特点，研究地面-履带-负重轮系统的耦合作用关系，分析了影响履带车辆动态特性的外部因素；借助于ATV软件，依据某履带车辆的具体结构尺寸，建立了履带车辆动力学分析仿真模型；研究了不同的地面地貌、车辆行驶速度及履带预张紧力条件下履带车辆动态特性的变化情况，分析了履带车辆动态特性变化与地面地貌、车辆行驶速度及履带预张紧力的内在关系规律，为履带车辆的设计和优化提供了依据。
