摘要
用设计变量表示统计能量法参数,建立统计能量法方程解得结构各频段能量值,用能量值表示目标函数,基于此建立基于统计能量法声振优化设计模型.对一个由两子系统构成的结构进行优化设计表明,由于能量随频率变化的光滑性,基于统计能量法的模型很适于优化设计.
Optimization variables are used in the SEA parameter formulas. The substructure frequency band energy got from the SEA equation is used in the target function. The vibro-acoustic optimization model is setup up. A calculation example made up of two subsystems is given. The results reveal that the model is suitable for optimization because the vibration energy varies with the frequency smoothly.
