摘要

针对高速膜盘联轴器工作过程中受到载荷突变影响，引起膜盘疲劳破坏和断裂失效的问题，对可冗余膜盘联轴器结构和动态性能进行了研究。首先，设计了可冗余膜盘联轴器整体结构；其次，建立了膜盘的有限元分析模型，计算得到了满足设计需求的膜盘最佳厚度；然后，对膜盘联轴器的冗余结构进行强度分析，证明了冗余结构的安全系数，并可以实现转矩的传递；最后，对膜盘联轴器的动态性能进行了研究，得到了频率响应曲线。研究结果可为该领域的机械传动装置结构分析提供有效依据。

Abstract

Aiming at the problem of the diaphragm coupling is affected by snap loads which lead to diaphragm fatigue broken and fracture failure， the structural and dynamic performance of the redundant diaphragm coupling are carried out. The overall structure of the redundant diaphragm coupling is designed， and the finite element analysis model of diaphragm disk is established， the optimum thickness of the diaphragm meets the design requirement is obtained by calculating. Then， the safety factor of the redundant structure is verified based on the strength analysis of redundant structure of diaphragm coupling， and the transmission of the torque can be realized. Finally， the frequency response curve is obtained based on the dynamic performance research of the diaphragm coupling. The results can provide the effective basis for the analysis of mechanical transmission devices in this field.
