Owing to the test of fatigue life,possesses a rather big difficulty and its testing data have the characteristics of strong scatterence and if a prediction is made from using grey-forecasting model GM(1,1,thus its prediction value would get a rather big error compared with the real result,This paper hereby put forward a kind of new method to simulate the test.let the data be firstly processed into logarithmic series so as to reduce the scatterence of data,and then carry out the prediction by the use of grey-forecasting model.

由于疲劳寿命试验具有难度较大，其实验数据具有分散性强的特点，如果直接用灰色预测模型（GM（1，1））作预测，其预测值与真实结果的误差较大。在此提出一种试验仿真的新方法。首先将数据处理成对数序列，以降低其数据分散性；然后再用灰色预测模型进行预测。
