This paper tests the influences of the machine vibration on the workshop structure by using the vibration testing method,and analyzes on the vibration regularity and reasons of the structure floor based on the testing result,which provides the reliable scientific foundation for the safety evaluation on the floor structure.

The present paper aims to introduce its author s testing and investigation of the impact of machine vibration on the building structure.

H_∞ control based on LMI for electromechanical vibration of a rolling mill main drive system;

The normal control of speed and current closed loop often lead to the phenomenon of electromechanical vibration and broken strip.

The output and quality of metal plate and strip are heavily affected by electromechanical vibration in rolling process.

A new method of real-time rotor eccentric load locating was proposed,which has solved the difficulty of real-time locating the rotor eccentric load accurately in high rotor speed,based on analyzing the rule and the cause of motor vibration,researching into the effect on motor vibration changing of eccentric loads with different weight and the quantitative analysis of motor vibration acceleration.

Because the wavelet packet decomposition is very sensitive to signal of the strange point, this characteristics can be used to follow the velocity signal of motor vibration.
