摘要
为了解决由于测量条件限制而产生的接触力难于测量的问题,利用近年发展起来的反分析法,并结合计算机模拟技术,给出了一种解决结构受到强冲击载荷时测量冲击力的通用方法。并将该方法应用到对压力管道耐撞性侧向冲击实验中冲击力的校核,给出了该冲击系统的传递函数h(t)。在实验测量值的基础上,得出了较为精确的冲击力时程曲线,从而验证了该方法的实用性。
The impact force time history of structures subjected to intense dynamic loading is one of the most important parameters measured. It is difficult to measure the contact force directly. In order to overcome the difficulties, the inverse analysis has been developed during recent years. This paper presents the application of the inverse analysis to the dynamic response test of pressure pipeline subjected to intense dynamic loading laterally. The transfer function h(t) is given by using computer simulation. The experimental data is justified, and more accuracy impact force history is obtained.
