摘要
针对自增强圆筒中的残余应力在温度影响下的松弛现象,运用灰色理论建立了稳态温度场作用下自增强残余应力的灰色预测模型。该模型的计算结果和实验结果吻合良好,为自增强残余应力松弛的数据处理提供了一种新的方法。
The residual stress relaxation of the autofrettaged tube in homogeneous temperature field is studied. A gray prediction model of autofrettage residual stress in homogeneous temperature field is developed based on grey theory. The calculated results by means of the model are in excellent agreement with the experimental ones. A new method for the data processing of autofrettage residual stress relaxation has been provided.
