Rotational autofrettage is one of the new and potential methods for strengthening thick-walled hollow circular disks/cylinders against internal pressure, thermal gradient, and rotational speed in service. The method makes use of the centrifugal force resulting from the high speed rotation of the disk/cylinder to induce plastic deformation at its inner side. On subsequent unloading of the centrifugal force, beneficial residual stresses are set up in the disk/cylinder. In this article, the method of rotational autofrettage employed in the disks is optimized. The rotational autofrettage is treated for an elastic–perfectly plastic axisymmetric disk incorporating Bauschinger effect. The best rotational speed is estimated to accomplish the procedure of rotational autofrettage in the disk such that the maximum stress level induced in the disk is minimized upon loading in service. To minimize the hoop/equivalent stress in the rotationally autofrettaged disk during loading in service, a one-dimensional optimization procedure, internal halving method is used.

旋转自动强化是加强厚壁空心圆盘/圆柱体抵抗内部压力，热梯度和使用中的旋转速度的一种新的潜在方法。该方法利用了由圆盘/圆柱体的高速旋转产生的离心力在其内侧引起塑性变形。在随后卸载离心力时，在盘/缸中建立起有利的残余应力。在本文中，优化了磁盘中使用的旋转自动强化方法。旋转自紧处理适用于结合了鲍辛格效应的弹性完全塑性轴对称圆盘。估计最佳旋转速度以完成磁盘中的旋转自动强化过程，以使磁盘在服务中加载时所产生的最大应力水平降至最低。为了最小化在使用中加载过程中旋转自动装填的磁盘中的环向/等效应力，使用了一维优化程序内部对分方法。
