| 摘 要： | 在已知转子工作时各种载荷引起的轴向松弛力和压紧力的前提下，本文提出综合考虑紧度裕度、强度裕度、装配关系等多因素的轴向预紧力确定准则，并由此建立了预紧力优化的数学模型，给出了５个目标函数以满足不同的设计要求。文中还介绍了根据本文的准则及方法开发的计算机程序及其应用实例

| Abstract: | Rotors with curvic couplings,which are separately prestressed from the front part and the rear part,are often applied to modern turboprop and turboshaft engines.It is very important but difficult to determine the values of preloads for a rotor.The prerequisite of the axial relaxed/pressed forces caused by variety of rotor loads in operation is available,the criteria to determine the axial preloads of rotors are proposed in this paper,which takes into account synthetically the factors,such as tightness margin,strength margin,assembling relationship and etc.Hence the optimiztion model of the axial preloads is established,and the corresponding solution is presented.The computer program is developed according to the presented criteria and method.Finally,an example is given. |
