摘　　要：动车组侧墙板是铁路车辆的关键组成部件,通常由高强度合金材料制成,受焊接和成型工艺影响,动车侧墙板与理论模型存在偏差。因此,当动车组侧墙板制成后,进行严格的质量检测是至关重要的。为了将腻子喷涂机应用于侧墙板制造过程中,改善侧墙板喷涂过后表面的平整度,设计了一种动车组侧墙板轮廓扫描装置。基于先进的激光测量技术,结合高精度的传感器与数据处理系统,能够快速准确地获取侧墙板表面的三维轮廓信息。相对于传统的测量装置,不受复杂曲面形态的限制。由于扫描装置在运行中不可避免地会产生振动,对数据采集过程会产生影响,利用加速度传感器,获取装置在扫描运行过程中的振动数据。通过对振动数据的分析,确定装置的主要振动模式,并进一步优化了相机的布局,较大程度降低了振动对数据采集产生的影响。The side wall panel of EMU is the key component of railway rolling stock,which is usually made of high strength alloy material.Affected by welding and molding process,the side wall panel of the motor car is deviated from the theoretical model.Therefore,when the side wall panel of the EMU is made,it is very important to carry out strict quality inspection.In order to improve the surface flatness of side wall panel after spraying with putty sprayer,a profile scanning device for side wall panel of EMU is designed in this paper.The device is based on advanced laser measurement technology,combined with high-precision sensor and data processing system,and can quickly and accurately obtain the three-dimensional contour information of the surface of the side wall panel.Compared with the traditional measuring device,the device is not limited by the shape of complex surface.Because the scanning device will inevitably produce vibration during operation,the process of data acquisition will be affected.In this paper,the acceleration sensor will be used to obtain the vibration data of the device during scanning operation.Through the analysis of the vibration data,the main vibration mode of the device is determined,and the layout of the camera is further optimized,so as to greatly reduce the impact of vibration on data acquisition.
