一引 言 用X射线法测量圆筒残余应力沿层深分布,一般采用逐次剥层法。利用外剥层法测量圆筒、圆柱应力分布的方法国内外都有介绍,这种方法的缺点是,在剥层时由于车削加工使外表面附加了应力,因此每次车削后都必须进行电解抛光以除掉加工层,不但耗时费工,深度也不易掌握。米谷 茂发展了的Schaal方法是内表面膛削,用照相法测量内表面残余应力,此方法可用来测量孔部周围切线方向的应力,但不宜用来测
I. INTRODUCTION X-ray measurement of residual stress along the cylinder depth distribution, the general method of successive delamination. The method of measuring the stress distribution of the cylinder and the cylinder by the method of exfoliation is introduced at home and abroad. The disadvantage of this method is that the stress must be applied to the outer surface after turning because of the turning process. Therefore, electrolysis must be performed after each turning Polishing to remove the processing layer, not only time-consuming, depth is not easy to grasp. Mitani developed Schaal method is the internal surface of the bore, the inner surface of the photographic method of measuring residual stress, this method can be used to measure the stress around the hole tangential direction, but not suitable for testing
