Study on the Proper Performance of Lift Buffers in Revised JIS A 4306 Using Non-linear Damping Characteristic

Japanese regulatory requirement was revised in 2016. Some important safety requirements were upgraded to ensure the safety of the lift passengers. The car and counterweight buffers play an important role in a safety system. This study has been conducted for an appropriate performance of the car and counterweight buffers to satisfy the revised JIS 4306. In this paper, the analytical results using a time response analysis is shown based on the non-linear damping effect.
