摘　　要：研究了铣削电主轴可靠性试验载荷谱的编制方法,调研和收集了国产170XD30铣削电主轴典型铣削工艺和数据。通过对相关切削数据的分析和计算,整理出了该电主轴载荷谱的样本数据,绘制了铣削电主轴载荷的相对铣削时间分布点图和累计相对铣削时间分布点图,初定总体分布模型并进行了参数估计。运用K-S检验法进行分布拟合检验,建立了国产170XD30铣削电主轴载荷谱的分布模型和五级试验加载谱。This paper researches how to establish the load spectrum for motorized spindle reliability test, which ba- ses on investigating and collecting the milling technology and data of the domestic 170XD30 milling motorized spin- dle. Firstly, the sample data of the motorized spindle＇s load spectrum was sorted out after analyzing and calculating the relative milling data. In addition, the frequency distribution point map and cumulative frequency distribution point map of the milling motorized spindle＇s load were drawn and the overall distribution model and parameter esti- mation were initially determined. Finally, it conducted a test of distribution fit by using K-S test method, builted the distribution model and the five-test load spectrum of the milling motorized spindle.
