摘　　要：建立联轴器动力学模型,并通过数值研究系统在不同激振频率比下的动力学特性,研究不同转速时不平衡激励力和不对中激励力共同作用情况,得到转速与不对中激振力关系以及轴系在不对中作用情况下响应情况,得到不对中量与响应的关系。Coupling dynamics model was built, and dynamic characteristics of different vibration frequency were got by numerical method. Coupling condition was also studied under different speed, unbalance excitation force, misalignment excitation force. It gained exciting force speed relationship and misalignment, compared to get the relationships of the misalignment of shaft in under the action of response under misalignment.
