| 摘 要： | 基于一维波动力学理论, 从冲锤与杆间接撞击的原理出发, 分析了等径冲锤获取不同几何特征应力波的可行性。在此基础上, 提出了通过改变等径等质冲锤撞击端曲率半径获取不同形式应力波形的新方法, 并得到了实验的证实。

| Abstract: | Based on the theory of one-dimensional wave dynamics and the interaction between impact hammer and rod, the possibility of obtaining stress wave with equi-diameter harmmer of different geometries was analysed, and a new procedure was proposed to obtain dif ferent stress waves through modification of curvature radius of equi-diameter and equimass impact rod in this paper.The accuracy of this method was verified by experiments. |
