摘　　要：动叶片围带间隙设计时,围带的间隙过大或过小对叶片的强度与振动有很大的影响,如果控制不好会造成致命的叶片事故,通过工程案例讨论了叶片围带间隙设计的重要性。There is a great influence on strength and vibration of the blades if shroud gap is too large or too small when designing Rotor blade shroud gap. Fatal accidents will happen if shroud gap is out of control.This paper will discuss the importance of the design of rotor blades' shroud gap through engineering cases.

关 键 词：叶片 围带间隙 有限元
