摘　　要：在正弦振动波形的基础上,利用分段函数法构造出一种非正弦振动波形,导出振动的6个工艺参数,建立了工艺参数优化的数学物理模型,给出了设计变量、约束条件、目标函数。先进行了单目标函数的优化,分别求出了6个分目标函数在约束条件下的变化范围,再利用转化指标法对6个分目标函数进行加权整合,给出多目标函数的表达式并进行求解。Based on sinusoidal oscillation waveform, a non-sinusoidal oscillation waveform was structured with the paragraph-function method, its 6 technological parameters were derived, a mathematical physics model for optimizing the technical parameters was established. The design variables, constraint conditions and objective function are given in this paper. The single objective functions were optimized first. The variation range of the 6 single objective functions under the constraint conditons is found out, and then the 6 single objective functions are integrated into muti-objective function by using transformation index method. Finally, the expression of a muti-objective function is presented and solved.
