| 摘 要： | 对脉冲激励下的双振子系统进行了瞬态统计能量分析,推导出了上升时间和峰值能量的数学表达式.在此基础之上,文中对系统进行了仿真研究,研究结果表明:峰值能量随着内损耗因子的增大而减小,随着耦合刚度的减小而减小;上升时间随着内损耗因子和耦合刚度的增大而减小.

| Abstract: | Transient statistic energy analysis for transient(TSEA) vibration of a two-oscillator system was presented.Mathematical expressions of the rise time and the peak energy were derived.Numerical modeling of the system was also made.It showed that the peak energy decrease as the internal loss factor increase and the coupling stiffness decrease,the rise time decease as the internal loss factor and the coupling loss factor increase. |

| Keywords: | transient response transient statistical energy analysis rise time peak energy |
