| 摘 要： | 对液性塑料心轴进行了有限元建模和分析，提出了一种优化设计薄壁套筒结构参数的方法。在ANSYS平台上建立了液性塑料心轴的轴对称分析模型，并分析了工件夹紧变形对加工精度的影响，定量地描述了套筒结构参数对心轴性能的影响规律。继而提出了一种优化薄壁套筒参数的方法。运用该方法对一个液塑心轴进行优化设计，使得工件的夹紧变形由7．46um减小到0．88um，同时套筒的最大应力由280．1MPa减小到204．7MPa，提高了液塑心轴的使用性能。

| Abstract: | Finite element method is utilized for hydraulic expanding mandrel design and an optimization method is presented for designing the thin-walled sleeve.An axisymmetric model of the mandrel is built in ANSYS,through which we discover the relation between the parameters of the thin-walled sleeve and the performance of the mandrel.As the clamping deformation of the workpiece has great influence on the machining accuracy,an optimization method is developed.A mandrel is optimized by using this method,decreasing th... |
