摘要
轨道车辆生产过程中在车厢底座铺设铝蜂窝板前,需对车厢车体底座面形进行测量,以便确定支撑点处橡胶垫的高度。由于底座的挠曲变形,各支撑点的高差是不同的,需要根据测量值进行整体拟合。在获得车体底座支撑点高差测量数据的基础上,提出了一种适用于轨道车辆的铝蜂窝板铺设的三点平面算法,该算法通过计算测量点到基准面的距离确定每个铝蜂窝板安装座的补偿高度,算法使用的数据基于轨道车辆智能化多曲面调整装置。该算法应用于轨道车辆生产过程的实践表明,算法能够按铝蜂窝板长度自动分段,确定支撑点处橡胶垫块的最佳厚度,使铝蜂窝板铺设平整、接缝处高差最小,算法稳健、可靠。
Before laying aluminum honeycomb panels on the carriage base in the production process of rail vehicles,it is necessary to test the surface shape of the carriage body base in order to determine the height of the rubber pad at the supporting point.Due to the deflection and deformation of the carriage base,the height difference of each supporting point is different,and the overall fitting needs to be carried out according to the measured value.On the basis of obtaining the measurement data of the height difference of the supporting points of the car body base,a three-point plane algorithm suitable for the laying of aluminum honeycomb panels of rail vehicles is proposed,in which the compensation height of the honeycomb panel mounting seat can be determined.The data used by the algorithm is based on the intelligent multi-surface adjustment device of the rail vehicle.By the practice of applying the algorithm to the production process of rail vehicles,it is shown that the algorithm can automatically segment the aluminum honeycomb panels according to the length,determine the optimal thickness of the rubber pads at the support points,so that the aluminum honeycomb panels are laid flat and the height difference at the joints is minimized robustly and reliably.
