With development of the hydro-electrical in china, the scale of the hydropower station is becoming bigger and bigger, at the same time the hydro-electric generating set also trends large-scale, high-capacity and high-parameter. At this point the vibration problems of hydro-electric generating set has become more prominent, it requires not only found them and solve them in the course of the operation, but also avoid them in the design process.

随着我国水电事业的快速发展，水电站的规模越来越大，同时水轮发电机组也向着高水头、大容量、高参数的方向发展，此时机组的振动问题也日益突出，这不仅要求在运行过程中发现问题，解决问题，更要在设计过程中杜绝问题。
