摘要


本文基于能量观点对振动主动控制系统进行了统计能量分析。首次推导出振动主动控制系统的统计能量关系式和耦合振子间耦合损耗因子的表达式,并通过实例研究了控制反馈系数对系统耦合损耗因子的影响,分析了阻尼对系统输入功率、子系统间传递功率流以及各子系统振动能量的影响。


Abstract

The statistical energy analysis (SEA) method was used to study the active vibration control characteristic of the system. The formulas of the statistical energy of the system and the coupling loss factor (CLF) was derived and the relationship between CLF and the active feedback coefficient was studied. The characteristics of the input power flow, the transfer power flow and the system vibration energy under different damping coefficients were studied in detail. The results are important to engineering problems and the development of SEA method.
