摘要
为更好分析及准确判断船用齿轮箱故障,以某江海直达货船推进轴系为研究对象,建立带齿轮副推进轴系的扭转振动模型,运用齿轮副时变啮合刚度理论计算方法,分析齿轮副在故障态下啮合刚度的变化,拓展传统推进轴系瞬态响应计算。基于有限元分析与信号处理软件得到考虑时变啮合刚度时正常态与故障态下带齿轮箱推进轴系瞬态响应频谱,并分析频谱中故障频率的成分与特点,为完整推进轴系齿轮副故障分析提供依据。
In order to locate and analyze gearbox faliure, the propulsion shaft of a river/cargo ship, the propulsion shaft of a river/coastal cargo ship was taken as a research object and the torsional vibration model of propulsion shaft with gearbox was established. By theoretically calculating the time-varying meshing stiffness of gear pairs and analyzing the variation of meshing stiffness while the gear pair is in failure, a widened method for calculating transient response of marine propulsion shaft was proposed. Based on the finite element analysis and signal processing, the spectrum of transient response was obtained, where the influence of time-varying meshing stiffness was considered. The characteristics of the fault frequency were analysed. It provides the basis for simulation and analysis of gear pair fault in propulsion shaft system.
