摘　　要：随着科技的发展,机械设备的安全性逐渐成为人们关注的焦点。破冰机的隔振系统决定其操作的安全性,因此,对振动破冰机的隔振效果进行了研究。首先介绍了破冰机的组成部分及主要参数,论述了机械系统的隔振原理。之后利用B&K测试软件对破冰机的激振部分与隔振部分的固有频率进行测试,排除共振情况。再进一步测试出破冰机的振动传递系数,求解出隔振率,证实了破冰机良好的隔振性能。另外,提出的测试方法对验证其他振动设备的隔振性能也具有一定的指导作用。With the development of science and technology,the security of mechanical equipment operation has become the focus of attention. Icebreaking machine vibration isolation system determines the safety of its operations; therefore,based on vibration icebreaking machine equipment,it studies the vibration isolation effect. It describes the parts of the ice-breaking machine and the main parameters ,discusses the principles of mechanical vibration isolation system,uses B＆K test software for the natural frequency of the exciting part and vibration isolation part,excludes resonance situation,further tests the icebreaking machine vibration transmission coefficient and solves the isolation rate,confirms that the ice-breaking machine has a good vibration isolation performance. In addition,the proposed test method also has a guiding role in verifying the vibration isolation effect of other vibration devices.
