Abstract
In order to relax the impact to the elevator system when the car or counter weight collides with the terminal, the buffers have been installed. In this research, the application examination of a small, cheap shock absorber utilizing plastic deformation to the elevator system is done. Moreover, it proposes the cylinder buckling type buffer as a plasticity shock absorber, and the static characteristic is confirmed by the FEM analysis and the examination. In addition, the buffer characteristic of this shock absorber is confirmed from the dynamic test with impact testing machine, and the utility is confirmed.
