方向舵纸基蜂窝芯零件夹持方法研究

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。

Study on rudder clamping method of paper honeycomb

Rudder part was studied as an example using the new 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 structure design for clamping device was fulfilled based on experiment testing and finite element analyzing. As the result, clamping position and the reaction force of the position were determined and the structure function was given in detail.
