摘要
针对航空发动机高涡转子过盈止口装配过程缺少规范化操作方法的现状,利用有限元分析软件ANSYS对装配过程进行仿真,通过计算高涡转子过盈止口装配过程中机件温度、变形及配合止口摩擦力等,给出高涡转子装配过程中机件冷却时间、压紧力、保持时间等装配参数,规范高涡转子过盈止口装配流程.
Abstract
To address the current situation of the lack of standardized operating methods for the assembly process of high-pressure turbine rotor interference-fit rabbets in aero-engine,the assembly process was simulated by using ANSYS analysis software.By calculating the temperature,deformation and frictional force of mating rabbets during the assembly process of high-pressure turbine rotor interference-fit rabbets,the assembly parameters such as cooling time,clamping force,and holding time for the components in the assembly process were determined,thus standardizing the assembly process of high-pressure turbine rotor interference-fit rabbets.
