摘　　要：为研究轨道车辆轮轨间的力学变化特征设计了一种轨道交通横向轮轨滚动振动实验台,包括Solidworks三维建模、机械结构设计、标准件选型、非标准件制造、工厂加工及装配应用。根据实际车轮和钢轨的几何尺寸和共振频率进行等比例缩小设计并进行模态分析与力学计算,设计轮轨模拟装置。在此基础上设计相应的轴重模拟装置、轴向驱动约束装置、轮轨角度调节装置、整体框架支撑装置,并在工厂进行制造与装配,经调试后进行轮轨横向蠕滑力特性曲线研究,发现轴重的增加可以抑制轮轨间的横向蠕滑进而减少轮轨损伤。A wheel-rail rolling vibration test rig was designed and manufactured for studying the mechanical changes in the wheel-rail system.The test rig includes Solidworks 3D modeling,mechanical structure design,selection of standard parts,manufacturing of non-standard parts,factory processing and assembly.The wheel-rail simulator was designed and analyzed based on the actual geometric dimensions and resonance frequencies of the wheel and rail.The corresponding axle load simulator,axial drive and constraint device,wheel-rail angle adjustment device,and overall frame support device were designed and manufactured in the factory.After the adjustment,the longitudinal creep sliding force characteristics curve of the wheel and rail was studied,and it was found that the increase in axle weight can suppress the lateral creep sliding between the wheel and rail and reduce wheel and rail damage.
