摘要

针对大转矩叠片联轴器承受载荷较大、开展疲劳寿命试验存在困难且成本较高的问题，开展大转矩叠片联轴器等效试验件设计，使其满足通用联轴器试验设备条件，降低试验成本；建立叠片联轴器等效设计原则，并基于等效对称循环应力，提出了一种大转矩叠片联轴器等效试验件设计方法。通过理论计算和有限元仿真分析，对比验证了该设计方法的准确性和可行性。

Abstract

It is difficult and costly to carry out fatigue life test for high-torque laminated couplings due to its large load. Therefore

the equivalent test piece is designed for high-torque laminated couplings to meet the requirements of universal coupling test equipment and reduce the test cost. The equivalent design principle of a laminated coupling is established

and a design method for equivalent test pieces of a high-torque laminated coupling is proposed based on equivalent symmetric cyclic stress. The accuracy and feasibility of the design method are verified by theoretical calculation and finite element simulation analysis.
