Optimal Design Method of Superstructure Vibration by Database Method (2nd Report) -Coupled Vibration Between Local Vibrating Body and Superstructure-

摘要

In vibration design of resonant avoidance to fore and aft vibration of superstructure, it is an important technology to estimate accurate natural frequency and to avoid it from resonant zone of blade or cylinder frequency in case of resonance. In this second report, authors investigated coupled vibration effect of local vibrating body such as funnel or dodger upon natural frequency of superstructure.
