Haul roads are designed to bear dynamic truckloads generated during haulage. Current road design methods consider static truckloads, which are lower than dynamic loads. They are also unreliable for designing roads for ultra-large trucks. This paper introduces a methodology for designing roads using dynamic loads for any haul truck. A 3D rigid multi-body dynamic virtual model of CAT 797F was built, verified and validated in MSC.ADAMS to model truck tire dynamic forces generated during haulage. Maximum dynamic forces were 2.86 times static force at rated payload. Industrial useable models that capture truck dynamics are proposed to improve road structural design.

拖运道路旨在承受拖运过程中产生的动态卡车负荷。当前的道路设计方法考虑静态卡车负载，其低于动态负载。它们对于设计超大型卡车的道路也不可靠。本文介绍了一种用于任何运输卡车的利用动态载荷设计道路的方法。在MSC.ADAMS中建立，验证和验证了CAT 797F的3D刚性多体动态虚拟模型，以模拟运输过程中产生的卡车轮胎动态力。在额定有效载荷下，最大动态力是静态力的2.86倍。提出了捕获卡车动力学的工业可用模型，以改善道路结构设计。
