Noise-reduction of the sliding guide is one of the major problems in the elevator system. This paper regards the cause of these noise phenomenon as self-excited vibration. Firstly, a prototype is made to evaluate the sliding guide in the elevator system which shows self-excited vibration caused by the asymmetry matrix of the system. Secondly, a simplified vibration model is introduced, and the radius of gyration and the position of the gravitational center are selected to suppress vibration using the existing stability criteria. Finally, the effect of vibration suppression is confirmed through several experiments changing these parameters, and the stability conditions of these parameters are quantified. The result of this study provides design method for suppressing vibration of the sliding guide in the elevator system.
