摘要
疲劳失效一般在工作初期不会体现,而工作一定时间后才出现断裂失效,因此它成为存在许多交变应力场合下的致命隐患。风机旋转的工作状态决定其中存在交变载荷,使得如蓄能器抱箍等随风机旋转的部件存在疲劳断裂的现象,本文针对风机安全工作对蓄能器抱箍疲劳寿命的要求,采用Solidworks对蓄能器抱箍进行建模,并用ANSYS对其进行强度、变形及疲劳断裂的仿真分析,合理解释抱箍断裂的原因,并针对寿命要求给出相应建议。
Fatigue failure usually does not reflect at the beginning, but after a certain period of time fracture failure will appear. This makes the fatigue fracture the bidden danger in many alternating stress occasions. The rotation working state of the wind turbine determines the existence of alternating load. And this cause the wind turbine component such as the embrace hoop break appears fatigue fracture. Aiming at the safe work right for the wind turbine accumulator embrace hoop fatigue life requirements, accumulator embrace hoop is modeled with Solidworks in this paper. Then the strength, deformation, and fatigue fracture are simulated with ANSYS. A reasonable explanation of the reasons for the breaking hoop and the corresponding advices for the life requirements are given.
