摘　　要：引入灰关联方法,分析了稳态温度场和交变压力对自增强残余应力松弛的影响情况.结果表明,在稳态温度场和交变压力的共同作用下,温度对自增强残余应力松弛的影响比交变压力的影响更大.According to the normal working conditions, two factors affecting the relaxation of autofrettage residual stress are analyzed with grey relational analysis method. The results show that, under cyclic pressure and homogeneous temperature field, temperature has more influence on the relaxation of autofrettage residual stress than cyclic pressure.
