摘要
为明确三角履带机构和地面间的作用机理,以小型三角履带车为研究对象,对履带板、支重轮、地面间的受力情况进行研究,推导出履带板与地面接触的任意点位沉降量计算公式.基于贝克理论和多体动力学理论在ADAMS中建立虚拟样机,对匀速直线运动、加速直线运动和匀速爬坡运动3种工况进行动力学仿真,分析得出各工况下履带板与支重轮之间的作用力分布情况以及履带板与地面的接地压力变化规律并与理论值进行比较分析,证明虚拟样机模型的正确性和有效性,为各类三角履带产品研发、通过性能和牵引性能测试相关的实验研究以及结构优化设计提供重要基础数据.
In order to clarify the mechanism of action between the triangle track and the ground, the small triangle tracked vehicle is taken as the research object and the force between the track plate, the supporting wheel and the ground is studied in the paper. We derive the formulas for calculating the number of points and the settlement of the contact between the tracked plate and the ground. Based on Beck′s theory and multi-body dynamics theory, the virtual prototype is built in ADAMS to have dynamic simulation of such three working status as uniform linear, linear acceleration and speed climbing. The distribution of force between the track plate and the support wheel and the variation of the grounding pressure between the track plate and the ground are obtained and compared with the theoretical values. The effectiveness and correctness of virtual prototype model is proved and it could be importance reference for travel performance research and structural optimization designs.
