摘要
设计了一种带平衡摇臂悬架且具备变轮距变地隙功能的移动平台(VII-HPC)。在传统分析的基础上,针对平台的变地隙、变轮距和变姿态工况进行了研究,总结出质心高度变化趋势、侧滑和侧翻、纵滑和纵翻的计算公式、边界条件和相应曲线,并对横向行驶变姿态工况下平台的稳定性作了分析和评价,同时通过对采用平衡摇臂悬架结构的平台与普通拖拉机的稳定性对比仿真,验证了其稳定性。
The VII-HPC power platform with the balance rocker suspension,variable ground clearance and variable wheel track was designed to meet special needs in the hilly regions.Variations of ground clearance,wheel track,and attitude of the VII-HPC power platform were studied by employing traditional approaches.The formula,boundary conditions and the corresponding curves on centroid height changing trends,sideslip and rollover,longitudinal slip and turning were summarized.Its stability was verified better than the ordinary tractor by simulation analysis.
