Abstract

In the installation of the elevator, work performs to correct the bending of the rail in order to suppress the lateral vibration of the car due to the irregularity of the guide rail. In this work, each rail bracket is adjusted so that the cutting edge of the rail is in the specified horizontal position with respect to the piano wire. However, since the rail is bent at the joint, irregularities remain even if the brackets are lined up in a straight line. Such a method cannot suppress the lateral vibration of the car and may worsen it. In this research, we proposed a method of optimizing the rail shape to minimize the vibration of the car based on a rail behavior model in that adjustment process and a car vibration model, and verified the effect by experiments using an actual elevator. As a result, we were able to suppress lateral vibration by 35% in a short working time.
