舰船行星齿轮减速箱的阻尼特性
|
摘要
大功率行星齿轮减速箱是船舶轮机系统的重要设备之一,由于减速箱在工作中承受的载荷大,且转速高、工作环境复杂,因此,舰船行星齿轮减速箱往往会出现噪声、振动和失稳等问题,影响舰船的正常运行。阻尼特性是弹性材料的一种特性,基于阻尼特性进行机械结构设计具有改善振动与噪声等优点,本文首先针对舰船行星齿轮的阻尼系统进行了阻尼建模,然后基于Ansys和Hypermesh等软件进行了行星齿轮减速箱的建模和有限元仿真,对改善行星齿轮减速箱的振动噪声等性能有重要的作用。
High-power planetary gear reducer is one of the most important equipments in marine engine system. Because of its heavy load, high speed and complex working environment, the noise, vibration and instability of planetary gear reducer often occur in ships, which affect the normal operation of ships. Damping characteristic is one of the characteristics of elastic material. Mechanical structure design based on damping characteristic has the advantages of improving vibration and noise. Firstly, the damping model of ship planetary gear damping system is established. Then, based on ANSYS and Hypermesh software, the modeling and finite element simulation of planetary gear reducer are carried out to improve the vibration and noise of planetary gear reducer. Performance plays an important role.
