摘要:
动力稳定性是细长杆件的一种重要性能，结合精细传递矩阵理论，建立了在轴向冲击荷载作用下受压杆件动力稳定分析的精细传递矩阵式，并对冲击荷载的参数进行了分析，研究其对受压杆件动力稳定性能的影响．算例表明：受压杆件的动力稳定性可以通过结构的位移响应曲线是否存在反规律现象来确定．算例还表明结构的动力稳定性不仅与冲击荷载的幅值有关，还有荷载的振动频率有关；荷载频率与结构自振频率之间的差异影响着受压杆件动力稳定承载力的大小．
Abstract:
Dynamic stability is an important property of slender bars. In this paper, a transfer matrix is developed for dynamic stability analysis of slender bars subjected to axial impact loading based on the theory of precise transfer matrix method, and the parameters of impact loading are analyzed, and the effect on the properties of dynamic stability of compression bar is studied. Examples showed that it can determine whether or not the dynamic instability of compression bar has happened by the displacement response curves there is against the law phenomenon, and the dynamic stability of compression bar is not only associated with the amplitude of shock load, but also with the vibration frequency of the load. The differences between the natural frequency of loading and the vibration frequency of structures have some effects on the size of bearing capacity of dynamic stability of compressive bar
