The problem of sequential loading-unloading a wheel with a deformable rod protector (tire tread) is considered. The presence of a slip zone in the contact zone with the road surface leads to different restoring forces during the loading-unloading process and to the energy losses due to dry friction. Two different approaches to finding the total normal reaction acting on the wheel from the road surface are proposed. The energy losses in the tire-road mechanical system are estimated on the loading-unloading cycle.

使用杆保护器装卸车轮时的磁滞损耗

考虑了具有可变形的杆保护器（轮胎胎面）的车轮的顺序装卸问题。在与路面的接触区域中存在滑动区域会导致在装卸过程中产生不同的恢复力，并导致由于干摩擦而产生的能量损失。提出了两种不同的方法来查找从路面作用在车轮上的总法向反作用力。轮胎-道路机械系统中的能量损失是根据装卸周期估算的。
