用 X 射线应力分析仪对强力旋压薄壁圆筒残余应力沿壁厚层深的分布规律进行了测定与分析.文中给出的 X 射线法测定圆筒产品三向残余应力分布计算公式,经实际应用验证是正确可行的,测试结果与其它四种方法的测试结果比较是相符的。最后对该产品中残余应力的形成机理进行了探讨.
X-ray stress analyzer was used to measure and analyze the distribution of the residual stress along the wall thickness of the thin-walled cylinder under strong spinning.The X-ray method is used to determine the three-dimensional residual stress distribution of cylindrical products, and the practical application Verification is correct and feasible. The test results are in good agreement with the test results of the other four methods. Finally, the formation mechanism of residual stress in this product was discussed.
