A ride comfort of elevator system is one of the important factors to enhance the product value. Elevator lateral vibration is the main problem that affects ride comfort. In order to improve ride comfort, it is important to achieve an estimation and optimum design of the cage suspension system. In this paper, a time domain simulator for elevator lateral vibration is developed. We made detailed simulation models of roller guide system and slide guide system in order to evaluate ride comfort on the design stage. Comparing with the simulation results and experiment results, guide system behaviors under various conditions become clear. The simulation models are improved with these behaviors. Fine matching of simulation and experiment are confirmed with the improved models.
