摘要: 报道一种球杆低速碰撞问题的理论与实验研究结果.通过球杆碰撞实验,验证了Hertz接触理论,并表明低速碰撞问题的分析的确可以转化为常规的振动响应问题的分析.因此,利用MSC/NASTRAN及其特殊数据卡就可计算此类问题.计算结果与实验数据吻合很好.另外,通过这个比较基本的实验,澄清了用激光测振仪测量撞击的一些技术问题,从而为以后更复杂的结构撞击实验提供了经验和技术.

Abstract: The analytical and experimental investigations of low speed impact of a ball on a bar were reported. The impact tests, which were carried out by means of laser vibrometer, verified the Hertz contact theorem. It was also shown that, the analysis of low speed impact problem can really be reformulated as the analysis of conventional dynamic response problem. Hence, such kind of problems can be calculated by using MSC/NASTRAN program and its special data card. The agreement between the experimental and analytical results is very well. Furthermore, some technical problems related to the impact measurement by using laser vibratormeter were clarified through this relatively fundamental impact test, thus providing the further more complicated structural impact test with experience and technology.
