考虑履带张力的履带车辆牵引力-滑转率分析与试验验证

Analysis and Verification of Traction Force-track Slip Ratio with Track Tension Taken into Consideration

为了研究履带车辆在砂土路面的通过性能,在接地压力试验的基础上,建立了考虑履带张力的接地压力分布模型。根据该接地压力分布模型以及履带与地面之间的相互作用规律,分析计算了考虑履带张力时履带车辆牵引力-滑转率的关系。最后,进行了履带车辆砂土路牵引力试验。结果表明:考虑履带张力的牵引力-滑转率计算结果与试验结果更加一致,为研究履带车辆在砂土路面的通过特性奠定了一定的基础。

In order to study the trafficability of tracked vehicle on sandy road,a ground pressure distribution model is built on the basis of ground pressure distribution and the influence of track tension on the ground pressure and the relationship between traction force and slip ratio are analyzed. Finally,a traction force experiment is carried out and the results show that the relationship between traction force and slip ration,which takes the influence of traction force into account is in accordance with the experiment data and lays a foundation for the trafficability of tracked vehicle on sandy road.
