摘要 本文研究了与弹性梁有两点接触的运动刚体对梁激励时的响应,以悬臂梁为例进行了数值计算及实验研究.发现运动质量在梁上运动时,梁呈非周期振动;而且,最先产生响应的位置大约在梁的中部,而不是在质量作用点或梁端部.实验验证了计算结果. The response of the beams activated by moving rigid body has been studied, and the numerical solution and experiment results are obtained in the case of cantilever beam. What is interesting is the vibration of the beam is non-periodical, and the location of the first displacement response of the beam is not at the terminal of the beam or at the point of the mass activated, but about at the middle of the beam.
