| 摘 要： | 基于虚拟样机仿真,建立大型风力发电机转子三维模型,应用Nastran仿真系统对转子圆锥支撑方式和筋支撑方式结构进行强度和刚度分析,并对转子支架结构以铸铁件代替焊接件进行可行性分析,仿真分析结果表明:圆锥支撑形方式比筋支撑方式的应力和位移小;转子支架用铸铁件形式比焊接件形式的应力、位移都小些.仿真结果对转子结构优化具有指导意义.

| Abstract: | Based on virtual prototyping simulation,three dimension model(solid model) of the rotor with a large type wind power generator is built,and virtual prototyping model of the rotor is established by a 3-D modeling software and Pro/Engineer.The solid model and virtual prototype model of circular cone brace type and muscle brace type structure are built.The analysis results of stress and displacement by using MSC.NASTRAN are presented.And the feasibility analysis of cast iron and weldment stock generation of rotor support structure is made.Based on results of simulation,this study provides guidana for optimizating the rotor of wind power generator. |
