摘　　要：磨削工艺参数的优化是提高生产率、改进工件质量和降低成本的重要手段。通过多元非线性回归分析建立高速飞行器天线罩(系复杂曲面薄壁回转体零件)加工形状精度的数学模型,根据最优化原理,针对传统优化方法的不足,将遗传模拟退火混合优化策略(GASA)用于实现以加工最大生产率和形状精度为目标的多目标优化,得出了最优的磨削工艺参数组合方案。根据优化后的结果设计并完成了相关的工艺实验,通过分析比较及实际应用,验证了该方法的有效性、正确性和实用性。The optimization of grinding parameters was a vital way to raise productivity, improve quality and decrease cost of work piece. The mathematical model of profile accuracy for rotary part on high-speed aircraft （large sculptured surfaces） is established by multivariate nonlinear regression analysis. According to the optimality principle aiming at the shortage of traditional methods, the compounded optimization strategy of genetic algorithm and simulated anneal （GASA） is used for multiple-objective optimization composing of max productivity and shape accuracy, and the optimum combination of grinding parameters is educed. Experiments were performed according to optimize result. The effectiveness and practicability of this method is validated by analy sis and ap p licat ion.
