Abstract Motion resistance of tyres directly contribute to the operational costs of all vehicles. Advances in the design and simulation of large off-road vehicles (construction, mining, agriculture etc.) have increased the need for accurate models of large off-road tyres. Vehicle OEMs use coast down and drawbar pull tests to determine the motion resistance of tyres used. Drum test rigs and motion resistance test trailers can also be used to determine motion resistance. Most research on motion resistance to date have been conducted on passenger car tyres with on-road truck tyres coming into focus. Motion resistance studies on agricultural tyres traversing over deformable terrain have been conducted in the past. However as more off-road vehicle are being used on-road OEMs of off-road vehicle are infesting in motion resistance measurements on non-deformable terrain. This paper compares different methods used to measure the motion resistance of a large lug tyre, as used in agricultural applications, on non-deformable terrain. Some basic considerations that need to be taken into account are the very low longitudinal forces that need to be measured compared to the large vertical load carried by the tyre and tyre operating conditions.

大型凸耳轮胎的运动阻力测量

摘要 轮胎的运动阻力直接影响所有车辆的运营成本。大型越野车辆（建筑、采矿、农业等）设计和仿真的进步增加了对大型越野轮胎的精确模型的需求。车辆 OEM 使用滑行和牵引杆拉力测试来确定所用轮胎的运动阻力。滚筒测试台和运动阻力测试拖车也可用于确定运动阻力。迄今为止，大多数关于运动阻力的研究都是在乘用车轮胎上进行的，公路卡车轮胎成为焦点。过去曾对农用轮胎穿越可变形地形进行运动阻力研究。然而，随着越来越多的越野车被用于公路上，越野车的原始设备制造商正在对不可变形地形上的运动阻力测量产生影响。本文比较了用于测量农业应用中在不可变形地形上使用的大型轮式轮胎的运动阻力的不同方法。需要考虑的一些基本考虑因素是，与轮胎和轮胎运行条件所承载的大垂直载荷相比，需要测量的纵向力非常低。
