| 摘 要： | 因残余应力而引起加工变形是飞机整体结构件制造的难题之一。运用裂纹柔度法测量了铝合金预拉伸板7075T7351的内部残余应力，分析了内部残余应力的分布规律，并测出厚度为40mm的板长度方向最大残余拉应力为18．3Mpa，最大残余压应力为17．9Mpa。

| Abstract: | It has become one of the most difficult technical problems to solve the distortion of the integrated part caused by the residual stresses during the machining process. The residual stresses in the pre-stretched aluminum alloy plate 7075T7351 are measured by using the crack-compliance method, and the distribution regularity of the residual stresses is analyzed in detail. Furthermore, the measurement done shows that the maximum residual tensile stress of the aluminum alloy plate 40 mm thick is 18.3 Mpa in the direction of its length and its maximum residual compression stress is 17.9 Mpa. |
