摘要
采用基于磁场和摩擦吸附原理的纸基蜂窝芯零件夹持方法,以某型号飞机方向舵蜂窝芯零件为对象,研究了区域划分单元的形式以及在确定的铣削条件下Z向变形与蜂窝芯高度的关系,利用实验测试和有限元方法对专用装夹平台进行了设计分析,确定了夹持点的位置以及夹持点的反力,最后给出了设计方案。
Rudder part was studied as an example using the clamping method based on the magnetic field and friction-clamping principle. The element forming of region segmentation and the relationship between Z direction deformation and honeycomb height were analyzed under the certain high-speed milling condition. With regard to the rudder part, a special structural design for clamping device was fulfilled based on test and finite element analysis. As a result, clamping position and the reaction force of the position were determined and the structure function was given in detail.
