摘要
研究双级隔振系统参数变化对隔振效果的影响,通过双级隔振器的隔振率分析,采用数值计算比较和理论分析确定了两种情况下隔振率与系统特征参数的关系,并对积极隔振的各种情形提出了特征参数的选取原则和物理参数的确定方法,并得出了频率比在各种情况下与隔振率的关系。为隔振器的设计提供理论根据。
The influence of parameter charge of double-stage arrester on isolation effect is researched in the paper. By the analysis of the vibration isolation rate of double-stage vibration arrester, the relation between the vibration isolation rate and characteristic parameters is determined in the two conditions. In the light of all situations of active vibration arresters, the choice principle of characteristic parameters and definition method of physical parameters are put forward. The relation of frequency ratio in different situation and isolation rate is required, which supplies theoretical basis for the design of arrester.
