| Abstract: | This paper researches how to establish the load spectrum for motorized spindle reliability test,which bases on investigating and collecting the milling technology and data of the domestic 170XD30 milling motorized spindle.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 estimation 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. |
