摘要

摘要: 共振转换器是舰船推进轴系纵向减振的有效装置,其对内部液压油脉动压力的滤波作用是实现其减振功能的技术条件。对共振转换器的各构成元件进行模化,基于平面波理论建立其传递矩阵形式的动特性方程,结合边界条件,推导出液压油脉动压力的传递函数。通过对其幅值谱分析可知,共振转换器在分支固有频率处出现反共振现象,可有效衰减液压油脉动压力,相当于对特定频率的脉动压力进行过滤。共振转换器的反共振峰值与分支最小阻抗密切相关,减小分支最小阻抗可提高共振转换器的滤波效果。单导管单容腔式共振转换器的滤波频带狭窄,为改善其滤波性能,提出3种变式结构的共振转换器。

Abstract: A resonance changer is an effective device expected to be used for the longitudinal vibration control of marine propulsion shafting. The work focuses on the filtering characteristic of a resonance changer. With the modular modeling conception, the transfer matrix equations describing the dynamic behavior of components of a resonance changer are deduced. In conjunction with boundary conditions, the fluctuating pressure transfer function of internal hydraulic oil is derived. By analyzing the amplitude spectrum, it shows that the resonance changer emerges anti-resonance phenomenon at the natural frequency of a branch, which can be used for amplitude attenuation of fluctuating pressure. This amounts to filter the fluctuating pressure of a certain frequency. The anti-resonance amplitude is closed with the minimum impedance of a branch, and the measure of decreasing the minimum impedance of a branch can improve the filtering effect of a resonance changer. Since the filtering frequency band of a resonance changer with a single pipe and a single chamber is too narrow, three modified resonance changers are presented.
