本文以静挠度最小及第一阶固有频率最高为优化目标，用极小极大法对主轴作了多目标优化设计，推导出一些计算公式，同时考虑主轴端和切削点的静挠度，使优化结果符合实际工作情况。
In this paper, the minimum static deflection and the first natural frequency as the optimization objective, the minimum pole method for the multi-objective optimization design of the spindle, derived some of the formula, taking into account the spindle end and the cutting point of static deflection so that the optimization results In line with the actual work.
