Abstract
Machine-Room-Less Elevator has the structure where a drive system is supported by the rail. So, the vibration generated at the time of an elevator run becomes easy to be transmitted to hoistway enclosure from a rail. For this reason, it needs to be cautious of the problem of generating noise in the room that adjoins by vibration from a hoistway. Then, the simulation technology for predicting the noise caused by vibration generated by elevator run was developed. Furthermore, this simulation performed optimization examination of a suppressing vibration design of elevator structure, and the effect was checked by examination.
