摘要以动力装置安装基座为研究对象，通过理论解释粒子阻尼的减振特性，借助有限元和离散元等仿真工具，确定粒子阻尼的初步设计方案，并通过振动特性及振动能量分析优化其布置位置，并对粒子的材质、粒径、填充率、表面摩擦系数、表面恢复系数等参数进行优化，确定最终的设计方案。设计仿真计算的模型验证试验台，通过减振特性测试，从粒子的材质、粒径、填充率、安装位置等角度进行验证。结果表明：粒子阻尼具有明显的减振效果，优化设计方案预期效果，并得到有效验证。该方法为动力装置安装基座的减振增添了新的控制手段，为进一步提升船舶隐身性贡献力量。

Abstract：Taking the installation base of a power plant as the study object, the vibration reduction characteristics of particle damping were explored theoretically. The simulation tools, such as, finite element method (FEM) and discrete element method (DEM) were used to determine the preliminary design scheme of particle damping. Its arrangement location was optimized with vibration characteristics analysis and vibration energy analysis. Particle parameters including particle material, particle diameter, filling rate, surface friction coefficient and surface recovery coefficient, etc. were optimized to determine the final design scheme of particle damping. A model verification test platform was designed for simulation calculation. The simulation results were verified with vibration reduction characteristics tests from the point of view of particle material, particle diameter, filling rate and installation position, etc. Results showed that particle damping has obvious damping effect, and the expected effect of its optimized design scheme is verified effectively; this method provides a new control means for vibration reduction of power plant installation base, and makes contributions to the further improvement of ship stealth.

Key words： power plant base particle damping vibration reduction optimization design
