摘要
用动态光弹性法和有限元法研究了带有圆孔的平面直杆在冲击载荷作用下动态应力集中的优化问题。结果表明,在主孔下游引入辅助圆孔可减小动态应力集中系数。文中得到了动态应力集中系数随辅助孔直径的变化规律,同时得到了辅助孔的优化尺寸。
Minimizing the dynamic stress concentration around holes in strut subjected to impact loading was studied in the paper.It is indicated that the dynamic stress concentration factor (DSCF) around the main hole will be reduced by introducing an auxiliary hole at the downsteam location of the main hole.The variation of the DSCF with the diameter of the auxiliary hole has been presented and the optimum size of the auxiliary hole has been ob- tained.
