摘要

为计算轨道车辆转臂式定位结构各向刚度，建立了转臂式定位结构的一系垂向、横向和纵向力学模型，同时利用受力关系、几何关系以及能量守恒推导了一系横向、垂向和纵向合成刚度的计算公式，并试验验证了各向合成刚度计算结果的准确性。结果表明，一系垂向和纵向合成刚度的试验与计算结果相吻合，一系横向合成刚度偏差较大，但通过改进工装可进一步提高试验精度。

Abstract

For calculating stiffness of rail vehicles tumbler locating structure, primary suspension vertical, horizontal and longitudinal dynamic model of tumbler locating were built, composed stiffness calculating formula of which was derived through balanceable force and moment, geometric distortion and conversion of energy and examined by test. The results showed that test results of primary vertical and longitudinal stiffness was consistent with design, yet test result of horizontal stiffness had greater error; furthermore, a better test method was put forward to improve testing precision.
