  • Modeling of High Speed Elevator Traction Machine Base and Investigation of Vibration Isolator

抄録

In recent years, an elevator becomes larger capacity and higher speed to cope with high-rise building. For example, a large capacity elevator capable of taking up to 90 passengers or a high speed elevator having a maximum speed of over 1000 m / min can be cited. Along with this change, safety and comfort are regarded as more important. However, it is problem that vibration and noise occur in a machine room and neighboring rooms by vibration growing big because of traction machine getting bigger. Presently, base of supporting traction machine and against vibration devise was set to solve this problem, but the method of anti-vibration design has not been clarified. As a result, excessive design is causing cost problems. From such a background, the object is to propose a member configuration that is simple in configuration and can exhibit high vibration damping effect. In this study, I model an elevator actual machine to use modeling method of preceding study and examine the protection against vibration design. In this paper, we report improvement of accuracy by improving the modeling method used in the previous research, and propose the possibility of vibration reduction by changing the mass of the members of the traction machine base.
