摘　　要：以水轮机过流部件的动水压力为切入点,根据振动理论和层流理论,对其振动模型和振动成因作了分析研究。并对宝鸡峡林家村水电站2#水轮机振动测量数据作了统计规律的分析,找出了该电站水轮机发生不允许振动＂区间＂和振动＂源＂,得出了可供科学运行借鉴的参考意见。Taking the hydrodynamic pressure at hydraulic turbine transition parts as the studying point and according to the vibration theory and laminar flow theory, the vibration model and its vibration causes are analyzed and studied hero, and the vibration data measured at 2# hydraulic turbine in Linjiacun Hydropower Station of Baojixia are also analyzed, at the same time, the interval of not-allowed vibration in the running of the hydraulic turbine and its vibration source are found out. At last, some suggestions are proposed which could be taken as the references to tackle similar problems.
