| 摘 要： | 就岩石动态应力－应变－应变率曲线测定中存在的严重振荡问题进行了讨论，提出了消除这一振荡的有效途径：改传统的矩形波加载为半周期正弦波加载。并就实现半周期正弦波加载的冲头结构进行了研究。

| Abstract: | The paper analysed the reasons for resuIting in a serious oscillation of rock dynamicstress-strain-strain rate curves obtained by SHPB subjected to the rectangular wave loading.In order to elimilate the oscillation,it is recommended that the traditional rectangular waveloading in rock SHPB experiments be replaced by the half single sine wave loading.Finally,the paper described a method of designing the impact rams geometries based on the expectedstress wave,and obtained the geometry of the impact rarn corresponding to a half single sinewave. |
