双合环应力分析（Ⅱ）──环体电测验证

Stress Analysis of Dual Semi-ring(Ⅱ) ──Check of Ring Body With Electrical Strain Gage Test

通过三副双合环电测数据验证，实测应变与计算结果相一致，另外，在结构上，凹槽处转角半径取Ｒ＝１ｍｍ，经四副双合环的爆破实验，证实是可行的。

For three pairs of dual semi--ring, data of strain test by electric strain gage arein accord with that of calculation. In addtion, through bursting tests of four pairs of dual semiring it is proved that taking the radius of fillet for channel R=1 mm is feasible.
