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. |
