动力失稳判别准则在非自治系统中的推广

Extension of a discriminant criterion of non-autonomous system for dynamical instability

通过假设,将结构动力失稳能量判别准则推广到非自治系统中,总结出在非自治系统中,结构动力失稳的能量判别准则,以此可判断出结构在外部激振荷载作用下(如简谐荷载,脉冲荷载,地震波等)的动力稳定性。

Based on assumption, a discriminant criterion for structural dynamical instability is extended to non-autonomous system. Summarizes the energy judging criteria of structural dynimical instability in non-autonomous system. This criterion could be used to judge dynamical stability of structures under external excitation, such as impact loading, harmonic loading and random loading.
