VIBRATION CONTROL ANALYSIS SYSTEM UTILIZING A MECHANICAL DYNAMICS MODEL

Speedy and accurate positioning is important for mechatronics products. It is necessary for optimum design to consider mechanical vibration and control. Control designs with mechanical vibrations have two problems: One is a difficulty to input suitable vibration characteristics, the other is an increase in the degree of an equation. Vibration characteristics influence system stability and collocation. This paper describes the analysis system for vibration control using FEM analysis. Mechanical vibrations are analyzed by FEM easily. This analysis system reads modal parameters from FEM output file and control block diagrams are input in dialogue. The analysis results are frequency response, step response and root locus. So it is possible to achieve optimum design for control with a mechanical system having multi-degrees of freedom.
