摘要
采用功率流的分析方法,对反共振机-楼板耦合系统的振动传递及功率流进行了分析。通过理论计算和分析,揭示了质量μ,机器-基础频率比α,隔振器阻尼损耗因子η1以及综合阻尼损耗因子η2等主要因素对反共振机-楼板耦合系统减振降噪性能的影响规律。
In this paper,vibration transmission and vibrational power flow in the coupled system of antiresonant vibration machine mounted on flexible floor are studied from the viewpoint of power flow.Through the theoretical calculation and analysis,the influencing law of the main factors of the system such as the mass ratio μ ,the machine foundation frequency ratio α ,the isolator damping loss factor η 1 and the combined damping loss factor η 2 upon performance of the coupled system of antiresonant vibration machine mounted on flexible floor in reducing vibration and noise were revealed.
