摘要

研发了一种立式筒状结构联轴器扭转刚度试验台，并研究了测试台的补偿模型。通过分析卧式试验台与立式试验台的误差成因，证明了立式结构的优越性；进行了扭转刚度测试台的误差分析与补偿实验，发现立式扭转刚度测试台具有刚度高、易补偿的特点，并依据这些特点建立了时域补偿模型；利用时域信号的错位对齐，使得力矩与角度在同一时刻呈线性关系，并通过最小二乘法拟合了转矩与角位移数据。试验验证结果表明，通过时域补偿模型对测试数据进行补偿，测试台可以达到较高的测试精度，满足联轴器扭转刚度测试的要求。

Abstract

A torsional stiffness test bench for vertical cylindrical couplings is developed and a compensation model for the test bench is investigated. The study illustrates the superiority of the vertical structure by analyzing the causes of errors between horizontal and vertical test benches. In this experiment

the steel bar is mounted on a torsional stiffness test bench for error analysis and compensation. The vertical torsional stiffness test bench is found to have the characteristics of high stiffness and easy compensation through experiment

and a time-domain compensation model is established based on these characteristics. The torque and angle are linearized at the same moment using the misalignment of the time-domain signal

and the torque and angular displacement data are fitted by the least squares method. It is experimentally verified that by compensating the test data through the time-domain compensation model

the test bench can achieve high testing accuracy and meet the requirements of coupling torsional stiffness testing.
