회전하는 멀티 패킷 블레이드 시스템의 과도특성

초록

Multi-packet blade systems usually undergo multiple nozzle excitation s during operation. For the design of multi-packet blade systems undergoing multiple nozzle excitation s, transient characteristics around an operating frequency and resonance frequencies should be identified. In this study the equations of motion of multi -packet blade systems undergoes multiple nozzle excitation s are derived. The reliability of the derived equations is verified by obtaining responses at resonance frequencies. Then, using the model, the effects of sys tem parameters on the transient characteristics of the system are investigated.
