摘　　要：为了测试弹性车轮轮对的轮轨力,根据70%低地板轻轨车辆转向架的一系悬挂结构,开发了一种新的轮轨力测量技术:在一系圆锥橡胶弹簧的钢质下支柱粘贴2组应变片,通过合理布点和组桥消除了垂向力和横向力测量电桥之间的相互干扰,从而直接测得作用在轴箱弹簧上的垂向力和横向力。使用这种方法测试了70%低地板轻轨车辆的刚性轮对和独立轮对的轮轨垂向力和轮轴横向力。In order to measure the wheel/rail forces on wheel set with rubber-layer wheels, a new measurement technology is developed according to the structure of primary suspension. The strain gauges are pasted on the steel spindle of cylindrical laminated rubber spring, then and the gauges bridge outputs of the vertical and lateral forces are completely irrelevant through special arranging bridge of stain gauges. This approach is ap-plied in the measurement of the vertical and lateral forces on stiffness wheel sets and independently rotating wheel sets of a new 70% low-floor tram.
