利用新型三点接触式疲劳试验机对3组共60粒Si3 N4陶瓷球进行完全疲劳寿命试验，并将最大似然估计法处理试验数据得到的结果与拉应力寿命模型预测的结果进行比对，结果表明，两者的误差小于5％，用该模型预测Si3 N4陶瓷球的疲劳寿命可显著减少试验时间，降低成本。
利用新型三點接觸式疲勞試驗機對3組共60粒Si3 N4陶瓷毬進行完全疲勞壽命試驗，併將最大似然估計法處理試驗數據得到的結果與拉應力壽命模型預測的結果進行比對，結果錶明，兩者的誤差小于5％，用該模型預測Si3 N4陶瓷毬的疲勞壽命可顯著減少試驗時間，降低成本。

The complete fatigue test for three groups of 60 Si3 N4 ceramic balls are carried out by using a newly devel-oped fatigue test rig with three-point contact.The test data is processed by using maximum likelihood estimate,the re-sult obtained by test data is compared with result predicted by tensile stress life model,with the error less than 5%.The results show that the fatigue life of Si3 N4 ceramic balls predicted by the model can significantly reduce test time,man-power and material resources,which is especially suitable for life prediction of Si3 N4 ceramic balls with long life.
