摘要
永磁推进电机是一种新型船舶动力装置。为满足其隔振和抗冲击等使用需求,本文开展了新型复合隔振装置研制,建立了隔振系统高频隔振性能对比分析模型,分析了系统设计参数对隔振效果的影响。基于分析结果提出了气囊隔振装置与硬弹性材料结合的新型复合隔振装置方案。研制出样机并进行了系列试验考核,结果表明其隔振效果、抗冲击性能、可靠性和轴系匹配性等均满足指标要求。研究成果也可应用于各类新型推进电机。
Permanent magnet propulsion motor is one of the most important power plants onboard new naval vessels.To meet the stringent vibration and shock isolation requirements,a novel compound mounting system(CMS)was developed.The high-frequency vibration isolation comparison models of mounting systems were established.The influence of system parameters on isolation performance was analyzed.Based on analysis results,a CMS comprising of air springs combined with hard elastic material was presented.A full-scale CMS prototype was manufactured and tested by a series of experiments.Test results showed that the isolation efficiency,anti-shock performance,reliability and compatibility with shafting of the CMS satisfied all the requirements.The CMS offers an effective solution for high-frequency vibration and shock isolation for the permanent magnet propulsion motor.Its application can be extended to other marine propulsion motors.
