冲压筋改变了板的固有频率和振型 ,从而能显著改变其振动和噪声特性 .用遗传算法来优化平板冲压筋尺寸 ,以最大程度地减小总的噪声辐射功率 .考虑了宽带激励下的声响应 。
The effect of rib stiffening causes the redistribution of natural frequencies and mode shapes of the plate,so as to alter its noise and vibration character. Genetic algorithm is used as a tool for sound radiation minimization problems for determining the optimal dimensions of the stamped rib in a plate. Acoustic response under broad-band excitation is considered. Radiated sound power is calculated using a boundary element method, in conjunction with a finite element solver.
