摘要
从模态力的角度研究了叶片模态振型对汽流激振力的响应特性，阐明了模态力的物理意义。给出了自由叶片、成组叶片和整圈连接叶片模态力的表达式，计算并分析了６８０ｍｍ叶片的模态力。
From the view of modal force, the response characteristics of blade vibration mode shape to the stimuli force are studied. The physical concepts of modal force are described. The modal force calculation formulas of single blade, grouped blades and whole circle connected blades are given. An example of modal force calculation results of 680mm blade is provided.
