Bridge Crane Structure Active Vibration Control Technology Applications

The article is based on the basic theory of vibration active control and practical engineering knowledge of crane ,researching on the effective control on vibration of main girder of 20/5t purpose double- girder overhead traveling crane under the condition of sudden rise or drop of cargo .The effect of result is proved effective with simulation software programmed on the platform of Matlab .The fact demonstrates that the excessive vibration of girder can be restricted by using theory of vibration active control .The aim of article is to show that by use of the technology of vibration active control can solve the problem of excessive vibration of metal structure.
