轮轨水平力连续测试技术的研究

Study on a progression technique for measuring lateral wheel/rail interaction force

根据轮轨相互作用的特点和轨道系统约束条件 ,提出了轮轨水平力和垂直力连续测试原理 ,并以钢轨作为传感元件 ,提出了轮轨水平力连续测试方法 ,通过有限元分析、试验室和现场试验 ,验证了连续测试原理和测试方法的正确性与可行性。

Based on the wheel/rail interaction characteristics and the restriction condition of track, this paper proposes a progression test principle for measuring vertical and lateral wheel/rail interaction force. The progression test method for measuring lateral wheel/rail interaction force is given when rail is served as the sensor. Analysis with FEM and some tests in laboratory and in situ has been carried out to validate the feasibility of this inspection system.
