基于统计能量分析理论,研究了相关输入形式下保守和非保守耦合振子的能量平衡方程,讨论了相关输入形式下保守和非保守耦合板结构的能量分布和功率流情况,并推导了板结构的能量平衡方程式及相关功率项的计算式,在此基础上进行了实验验证。研究结果表明,用考虑了输入形式之间相关性的修正的统计能量分析方法预测的保守和非保守耦合板结构响应结果,与实验测量结果之间的一致性优于用经典的统计能量分析法预测的振动响应。
Based on the theory of statistical energy analysis, the energy balance equations of the conservative and non-conservative coupled oscillator under the relevant input form are studied. The energy distribution and power flow of the conservative and non-conservative coupled plate structures under the relevant input form are discussed. Energy balance equation and related power terms of the formula, on this basis, the experimental verification. The results show that the agreement between the experimental results and the conservative and non-conservative coupled plates predicted by the modified statistical energy analysis method, which takes into account the correlation between the input forms, is better than the classical statistical energy analysis Predicted vibration response.
