摘　　要：针对传统铁路轨道检测效率低、精度差、数据不可存储等缺点,设计了一种激光检测平台。该检测平台具有模块化、结构简单、调节效率高、适应性强等优点,解决了激光检测平台在铁轨上行走时,激光光面相对于轨道轴线垂直调节困难的问题。利用Solidworks2013软件对机构进行设计与建模,采用D-H法对机构执行端的空间位置进行了正逆解计算。使用Adams对虚拟样机进行运动学仿真分析,结合解析法,求出机构的工作空间。进行了物理样机的现场试验,结果表明检测平台满足轨道检测的最佳距离和垂直调节要求。A platform of laser detection was designed aiming at the defect of the traditional railway track detection such as low efficiency, poor accuracy, data cannot be stored, which has the advantages of modularization, simple structure, high regulation efficiency, strong adaptability, overcoming the vertical adjustment difficulty of the laser relative to the rail surface with the laser detection platform in the walk on the rail. The structure of the mechanism was designed and modeled by solidworks2013 software. The D-H method is used to calculate the positive and inverse solution of the spatial position of the execution end. Adams is used to obtain the kinematics simulation of the virtual prototype, Combining with the mathematical analysis method, figure out the working space of the mechanism. The physical prototype test result shows that the mechanism can meet the requirements of the optimal distance and vertical adjustment.
