2.The truck model is based on the H20-44 truck design loadings included in the American Association of State Highway and Transportation Officials (AASHTO) specifications [18],its total mass is approximately
19 tons.This truck has been used by other authors,e.g.[19,5].Mechanical properties are summarized in Table 1,eigenmodes and eigenfrequencies of the truck model are shown in Fig.2.
Linear behaviour for suspensions and tyres is assumed,although nonlinear suspensions or wheels could be also employed without any additional complication in this framework.Models of this type with linear suspensions and tyres are widely used in the literature (e.g.[8,20]) and are considered to represent vehicles with sufficient precision in vehicle–bridge interaction problems.In this work vehicles are considered in normal running conditions,hence suspension system nonlinearities are not taken into account.The methodology could be also easily extended to other kind of vehicles:trucks with more than two axles,cars,articulated lorries,etc.

2,卡车车型是基于H20-44卡车的设计荷载,其列入（美国）国家公路和运输官员协会（AASHTO）规范中[18],它的总质量大约是19吨.这种卡车已被其他作者所采用,例如文献[19,5].机械性能归纳在表1中,卡车车型的本征模式和本征频率示于图2.假设悬架和轮胎为线性行为,不过非线性悬架或车轮也可以采用而不至于在这个框架中有任何额外的复杂性.这种采用线性悬架和轮胎的车型被广泛用于在文献中（例如,文献[8,20]）,并且被认为是代表了在车辆－桥粱相互作用问题中具有足够精度的车型.在本研究,车辆是在正常运行条件下加以考虑的,因此,悬架系统的非线性不加以考虑.该方法还可以容易地扩展到其他类型的车辆：两轴以上的卡车、轿车,铰接式卡车等.
