| 摘 要： | 研究刚性矩形框内板状结构的流固耦合影响。基于粘性流理论推导出多层叠层板状结构和刚性矩形框内的流体动压近似理论解析表达式。得到系统的附加质量系数、附加刚度系数和附加阻尼系数。结果表明流体的耦合系数与板间距相关：附加质量系数与板间距的大小成正比；附加刚度和附加阻尼系数与板间距的立方成反比。

| Abstract: | The fluid coupling effects of plate-type structure in a rigid rectangular tube were studied. An analytical investigation of fluid pressures for parallel plates and plate in a rigid rectangular tube were presented. The added mass, added stiffness and added damping coefficients were obtained. The analytical results show that these coefficients are greatly influenced by gap spacing: the added mass coefficient has direct ratio with gap spacing while the other two coefficients have inverse ratios with the cube value of gap spacing. |
