摘要
建立了柔性中间质量与刚性中间质量双层减振系统减振性能对比分析模型,分析了主要设计参数对减振效果的影响规律.设计了一种集成式、可调节双层减振模块,利用其结构形式灵活、设计承载能力范围广等特点,实现在紧凑结构空间的布置,相比传统柔性中间质量浮筏减振装置,尺寸质量大幅降低,同时具有较好的减振、姿态控制性能.基于某船舶动力装置研制样机并开展了减振效果与姿态控制精度试验,结果表明:相对传统浮筏减振装置,在质量减轻50%的条件下,模块化减振装置的减振效果可达到要求,并具有良好的姿态控制精度.
The vibration isolation effectiveness(VIE)performance comparison models of two-stage mounting system with flexible and rigid intermediate mass were established,and the influences of system parameters on isolation performance were analyzed.Based on analysis results,a novel integrated adjustable two-stage mounting module with flexible structure form and wide range of design bearing capacity was designed,which could be arranged in compact structure space and could greatly reduce the total size and weight of mounting device compared with that of traditional floating raft mounting system with flexible intermediate mass.Meanwhile,it exhibited great vibration attenuation and attitude control performance.Vibration isolation effectiveness and attitude control experiments were carried out based on a ship power plant prototype.Results show that the novel modularization mounting system meets the VIE index with 50%weight reduction compared with traditional floating raft mounting system,and presents good attitude control accuracy.
