Structure Optimization of Precision and Double Feed Honing Head

以高精度双进给中型珩磨头为研究对象,通过ANSYS软件对磨头体进行静力分析,运用控制变量尺寸优化方法,研究了结构优化在珩磨头中的应用。利用有限元法,在理论研究的基础上,首先运用Pro/E和有限元分析软件ANSYS建立了高精度双进给珩磨头的有限元模型,在此基础上,对磨头体进行了静力分析。通过等应力分布图,找出了待优化的参数,利用有限元分析得出各参数的最优尺寸,获得结构优化的改进方案,最后加以比较验证。在结构优化的同时减轻了自身重量,对提高珩磨头加工精度有重要影响。

h, whose research object is high-precision double feed medium honing head, studies the application of structure optimization in honing head by the static analysis of the grinding head with the aid of ANSYS software and by the size optimization of controlled variables. The finite element method is used here. On the basis of theoretical analysis, Pro/E and finite element analysis software ANSYS are used to establish the finite element model of high precision and double feed honing head. Static analysis is made for the assembly body of honing head after modeling. At first, variables to be optimized are found out by isostress distribution chart; then the optimal size of each variable is determined by means of finite-element analysis; at last, the improvement project of structural optimization is proposed and verified. Through the very structure optimization, the weight of the grinding head is reduced, which will hove a significant impact on the improvement of the machining precision of the honing head.
