摘要
本文阐述风机弹簧减震器的选型与校核计算。利用隔振效率得出当弹簧减震器的工作频率大于5倍的固有频率时,弹簧减震器的减震效果可以达到95.8%以上。通过简单的计算可以验证所选的弹簧减震器是否合理。如果验算未能达到预期要求,可以采取加大基座重量或增加弹簧减震器的数量以及选取较低弹簧减震器的刚性系数等措施来达到期望的减震效果。
In this paper,the selection and checking calculation of fan spring absorber are introduced. By using the vibration isolation efficiency,it is obtained that when the working frequency of the spring shock absorber is 5 times greater than the inherent frequency,the damping effect of spring absorber will reach more than 95.8%. According to simple calculations,it can be checked if the selected fan spring absorber is reasonable. If the calculation fails to meet the expected requirements,the desired damping effect can be achieved by adding the weight of the base or increasing the number of fan spring absorbers and choosing lower stiffness coefficient of the spring shock absorber.
