基于有限元分析的双联叉专用夹具设计

Design of special fixture in duplex fork based on finite element analysis

文中通过分析双联叉的加工工艺,利用有限元网格划分软件对双联叉进行网格划分,并用软件ANSYS分析双联叉在夹紧力作用于不同作用点时双联叉孔的变形量,从而确定最佳定位方式,有效减少孔的变形,提高双联叉的加工精度。结合三维CAD来优化设计双联叉夹具,确保准确性,缩短夹具设计周期。

With the analyses the process of a duplex fork, the mesh was generated by finite element meshing software. The deformations of duplex fork holes at different working points under the fixture forces were calculated using ANSYS. The optimal position point was determined. The deformation of holes could be reduced effectively. The machining precision of the duplex fork was improved. The design of the duplex fork clamp was optimized designed to ensure the accuracy. The design cycle of fixture was reduced.
