B Through theoretical and experimental studies, the paper investigats the relationships between hammer geometer and stress waveform generated by the hammer. After the mechanical meanings of linear model used by others are demonstrated, a simple expression of rigidity of an equivalent spring for direct impact between a hammer and a rod is obtained. Based on the above work, a mathematical model and numerical method for the impact of the hammer with progressively changing cross-section on the rod are presented.

2应用理论分析和实验研究相结合的方法，探讨了冲击应力波波形和冲锤形状尺寸之间的关系；阐明了冲锤与杆撞击局部变形的线性模型的物理意义，继而分析讨论了冲锤端头曲率半径与撞击弹簧刚度的关系；在此基础上，提出了连续变截面冲锤与杆撞击的数学模型和计算方法。
