摘要
为进一步降低热动力鱼雷噪声,文中提出了一种多激励源激励下的动力及推进系统有限元简化建模和振动响应分析方法。首先建立了包含各隔振环节的有限元模型,对轴系前后隔振环、动力装置整机隔振圈和联轴器进行建模简化,通过有限元静力仿真确定各个方向的静刚度;分别提取动力装置、推进轴系和推进器等激励源对模型的激励力,并将其施加到有限元模型中;最后基于模态叠加法求得壳体表面的结构振动响应。文中结论可指导鱼雷隔振设计,并为进一步的隔振参数优化提供参考。
To reduce the noise of a thermal power torpedo, a method for simplified finite element modeling and vibration response analysis of its power and propulsion system excited by multiple excitation sources is proposed. The finite element model including each vibration isolating link is established. Simplified modeling of the front and rear vibration isolating rings of shafting, the vibration isolating rings of whole power plant and the coupl er is carried out, and the static stiffness in each direction is determined by finite element static simulation. Then, the exciting forces of engine, propu lsion shafting system and propeller on the model are extracted and applied to the finite element model. The structural vibration response of the shell surface is obtained based on the modal superposition method. This study may provide a reference for design of torpedo vibration isolation and further optimization of vibration isolation parameters.
