摘要
针对传统履带式移动平台转向滑动摩擦阻力大的问题,提出一种新型履带式移动机构及其平台—高效转向履带及其平台。为了研究高效平台的转向性能,分析与比较高效平台与等同条件的传统平台的转向滑动摩擦阻力矩以及驱动效率。基于ADAMS和Matlab软件,分别建立高效平台和传统平台的虚拟样机,包含平台多体动力学模型和电机模型,并利用上述两种样机在平面上进行中心转向和B/2转向的仿真分析。仿真结果表明,在相同转向条件下,高效平台比传统平台的转向驱动力矩减小约30%。因此,高效平台能够减小传统平台的转向滑动摩擦阻力矩,从而改善传统平台的转向性能。
For the problem of traditional tracked mobile platform＇s large steering friction resistance force, it proposes a new tracked mobile mechanism In order to study the steering perfornance of the efficient platform, analyzes and compares the steering friction resistance moment and drives efficiency of efficient platform and traditional platform on the same condition. Based on ADAMS and Matlab, a virtual prototype with the models of multi-dynamics and motors was established. It accomplished the simulation analysis of zero turning radius and B/2 turning radius on plane by utilizing the two prototypes. The results of simulation indicate that, efficient platform＇s steering drive moment reduced about 30% compared with traditional platform on the same steering condition. Therefore, the efficient platform can reduce traditional platform＇s steering friction resistance moment and improve the steering performance of traditional tracked mobile platform.
