摘　　要：针对废钢破碎机存在的振动过大的问题,本文应用弹簧阻尼隔振技术进行隔振。根据隔振理论,采用弹簧阻尼隔振器,设计调谐比为3.74,阻尼比约为0.1,使破碎机传到主控室以及地基的振动速度的最大值由4.83 mm/s降至1.82 mm/s。两年的实际运转表明,该设计保证了操作工人的身体健康,提高了设备以及附属建筑结构的安全性,隔振效率比原设计提高30%以上,具有广阔的市场前景。We apply spring-damper vibration isolation technology to a steel scrap crusher for the issue of its excessive vibration. Based on vibration isolation theory, we design a spring-damper isolator with tuning ratio of 3. ？4 and damping ratio of 0. 1. It reduces the maximum vibration velocity to control cabin and foundation from 4.83 mm/s to i. 82 mm/s. Twoyear practical operation demonstrates that the design can guarantee the health of workers and enhance the safety of a crusher and outbuildings. Vibration isolation efficiency increases by 30%, as compared with the original design. The vibration isolation design therefore has broad market prospect.
