摘要

摘要: 合理控制推进轴系振动可有效降低水下航行器结构噪声辐射。文中考虑非线性作用力、平行不对中和转轴质量偏心的耦合因素, 建立轴系匀速运动过程的横向振动微分方程, 仿真分析了平行不对中量对轴系非线性振动特性的影响, 并根据数值计算结果制定平行不对中量的工艺控制标准。研究表明, 平行不对中、非线性作用力和质量偏心的耦合作用, 导致轴系产生混沌与分岔等非线性动力学行为, 复杂的振动特性决定了应用现有理论控制轴系非线性振动十分困难, 而采用制定轴系参数工艺控制标准的方法可有效抑制轴系非线性振动。文中研究可为控制水下航行器推进轴系振动和噪声辐射提供参考。

Abstract: Reasonable control of propulsion shafting vibration can effectively reduce the structural noise radiation of an undersea vehicle. In this study, a differential equation of shafting transverse vibration in uniform motion process is established considering the coupling of nonlinear force, parallel misalignment and eccentric mass of rotating shaft. The influence of parallel misalignment amount on the shafting nonlinear vibration characteristics is analyzed via simulation. And the process control standard of the parallel misalignment amount is proposed according to the numerical calculation results. It is shown that: the coupling effect of parallel misalignment, nonlinear force and eccentric mass leads to the nonlinear dynamic behaviors of the shafting, such as chaos and bifurcation; the existing control theory is not applicable to the control of shafting nonlinear vibration due to the complex nonlinear vibration characteristics, while establishing the process control standard of the shafting parameters can achieve the purpose of restraining the nonlinear vibration. This work may provide a new method for controlling the propulsion shafting vibration and noise radiation of an undersea vehicle.
