Abstract
As a problem about elevator, it is concerned that vibration generated in elevator traction machine transmits to the adjacent room through the beam of building. Therefore, base supports elevator traction machine with vibration isolator is installed to resolve the problem. However, many isolators are used for elevator traction machine base to guarantee much of safety in some cases. Hence, the purpose of this study is to select the most suitable vibration isolator and suggest the design of framed structure can provide a high damping effect. In previous study, some experimental devices in imitation of an actual machine were made. Furthermore, vibration experiment and consistency verification were carried out. Consequently, good simulation results were obtained. However, it was necessary to identify various parameters by making trial and error in the process of modeling. This paper proposes a systematic parameter identification method. Unknown parameter is spring constant of bolt joint. In addition, if dimensions of bolt were same, we verified the value of spring constant almost accorded in multiple models.
