针对现有各种托辊旋转阻力测试方法中,难以进行在不同托辊负载和转速下测试,在测试精度以及应用便捷性方面存在的问题,设计了一种基于普通车床的托辊旋转阻力测试装置。该装置由托辊卡具、压力传感器、放大器和USB数据采集卡组成,在Labview软件支持下,使用普通笔记本就可以进行测试。对该测试装置的测试方法和测试数据误差进行了分析和实际检测,分析认为用正反转测试方法可显著降低数据误差;实际测试数据表明该测试装置的实验数据误差小,重复性好。

Aiming at the problems existing in the existing rotation resistance test methods of rollers, it is difficult to test under different load and rotation speed of rollers, and the problems of testing accuracy and convenience of application are analyzed. A rotation resistance test based on common lathe is designed Device. The device consists of roller clamps, pressure sensors, amplifiers and USB data acquisition card, with Labview software support, the use of ordinary notebook can be tested. The test method and the test data error of the test device are analyzed and actually tested. The analysis shows that the data error can be significantly reduced by using the forward and reverse test method. The actual test data shows that the experimental data of the test device has small error and good repeatability.
