摘　　要：针对传统人工轨道检测方法工作强度大、检测效率低、成本高的缺点,利用三维数字化检测技术,设计了一种基于结构光技术的轨道检测平台,能够简单快捷地测量多个轨道相关参数。采用空间解析几何法对结构设计的合理性进行验算分析。对平台进行了力学平衡性分析,并给出了外推力的有效值。使用Creo Parametric 2.0软件建立了整体机构的三维模型,并将模型导入到虚拟样机仿真软件ADAMS中,对模型进行动力学仿真分析,给出了平台在不同外力作用下的受力情况,验证了计算分析的正确性。The disadvantages of high labor intensity,low detection efficiency and huge cost exist in using the traditional detection method.This paper uses three-dimensional degital detection technology to design a track detection platform based on structured light technology.This platform can be used to easily and quickly measure the relevant parameters of the rail.The rationality of the structure design is analyzed and calculated based on the space analytic geometry method.The mechanical balance of the platform is analyzed and the effective values of the external thrust are given out.The three-dimensional model of the whole mechanism is established by use of Creo Parametric 2.0 software and the model is imported into virtual prototype simulation software ADAMS to make the dynamic simulation and analysis.The stress situation of the detection platform is given and the correctness of the calculation is verified.
