摘要
提出了一种全新的测量轮对外形尺寸的方案,即采用车轴基准探尺测定轮对的轴线,以并联式机构和旋转测头作为传感器的执行机构,扫描轮辋断面的轮廓线,由此计算出轮对的相关外形参数。分析了该机构中各单一因素对测量误差的影响,得出了误差补偿的依据。借助虚拟仪器的思想,结合计算机控制,完成了测量系统的电气部分设计。通过电涡流传感器非接触式扫描测量试验,进一步证明了该测量系统的可行性。
A completely new measuring scheme is put forward. The axis probe is applied to determine the center line of wheelset axis.As the excetution unit of the sensor, the parellel unit and rotating probe scan the whole wheel tyre profile so as to calculate the relevantprofile parameter of the wheelset. Influences of the single factors in the unit on measurement tolerances are analyzed, which is the basis fortolerance compensation. Through the idea of virtual instrument and with computer control, the design of the electric part of the measuringsystem is finished. The non-contact scanning experiment with eddy current sensor further proves the feasibility of this measuring system.
