Linearization Method and Vibration Analysis of a Constrained Multibody System Driven by Constant Generalized Speeds

일정 일반속력으로 구동되는 구속 다물체계의 선형화기법 및 진동해석

This paper presents a vibration analysis method for constrained mechanical systems driven by constant generalized speeds. Equilibrium positions are obtained first and vibration analysis are performed around the positions. The method developed in this paper employs partial velocity matrix to obtain a minimum number of differential equations. To verify the accuracy of the proposed algorithm, linear vibration analyses of two numerical examples are performed and the results are compared with results from a commercial program or previous literature.
