从受扭圆轴M—φ图的相互换算公式出发,利用Nadai公式,推导出大直径受扭圆轴经弹塑性状态后的残余剪应力计算公式,计算简便、准确,在理论上较好地解决了这一问题,并弥补了各种实测法的不足。
Starting from the mutual conversion formula of M-φ diagram of torsional circular axis, the formula of residual shear stress of large diameter torsional circular shaft after deduction of elastic-plastic state is deduced by Nadai formula. The calculation is simple and accurate and theoretically better Solve this problem, and make up for the lack of various measurement methods.
