  • 摘要: 基于结构动力学优化设计理论,研究了潜艇典型舱段双层圆柱壳舷间高传递损失复合托板结构。通过初步优化,得到隔振效果最优的刚性阻振质量块的最优截面尺寸和布设位置,并将最优参数的刚性阻振质量块等效为相同截面惯性矩的球扁钢。在满足舱段总重量及危险截面结构强度的约束条件下,以舱段非耐压壳体全频域内的平均振动加速度级为目标函数,对高传递损失复合托板的开孔半径和托板角度进行动力学优化设计,得到最优振动特性的复合托板形式。由优化结果得到,在中、高频段内,高传递损失复合托板有明显的降噪作用,舱段非耐压壳体全频域内的平均振动加速度级降低了1.66 dB。
    Abstract: On the basis of the structural dynamic optimization design theory,this paper investigates the structure of the composite pedestal of a typical submarine double cylinder shell with high transmission loss. To achieve the optimum vibration reduction,the exact sectional dimensions and positions of the rigid vibration isolation mass is first determined through preliminary optimization. Next,the rigid vibration isolation mass is equated with a bulb flat with the same section moment of inertia. By considering the restriction of the gross weight and the structural strength of dangerous sections,the structural dynamic optimization formula is established. Basically,the objective function minimizes the average vibration acceleration of the non-pressure hull for all frequencies,and the design variables such as the hole radius and the pedestal degree are carefully chosen. Results show that the composite pedestal with high transmission loss considerably reduces the vibration noise in the medium-high frequency range,where the average vibration acceleration of the non-pressure hull is decreased by 1.66 dB.
