To this problem, on the basis of the work property and characteristics of the water turbine ' s blade. the finite element mechanics model of blade vibration characteristic is described with the eight - node three - dimensional nonconforming and all parts of blade damp are analysised, the calculating model of blade damp is built, the tackling method of blade damp in calculating of dynamic stress is presented
本文根據水輪機葉片的特點和工作性質，採用空間八結點非協調等參單元描述水輪機葉片運動特性的有限元力學模型，詳細分析了水輪機葉片阻尼各組成部分，並建立了葉片阻尼的計算模型，提出了葉片阻尼在動應力計算中的處理方法。 -
In fact, the outlet flow of vane in the hydroelectric set is non - uniform flow for a variety of possible reasons. the flow is unsteady flow relative to vane and blade, and it is the main factor that affect self - excited vibration and dynamic characteristic of guide vane and hydraulic - turbine, which affect directly the power set to run safely and stably
非均勻來流相對于導葉、葉片必然是一種非定常流。這種非定常流造成導葉和轉輪葉片的激振，是產生導葉和葉片動應力，改變它們頻率的最主要因素，而導葉和葉片的動力特性直接影響水輪機的穩定性。
