本文对埧內式水电站重力埧(空心重力埧)的自振特性进行了初步的理論分析与实驗研究。文中根据能量法原理,导出了埧內式水电站重力埧的順河向第一自振頻率的理論计算公式,並經过模型試驗的印証,理論与实驗基本符合。本文並就埧內式水电站空心重力埧与实体重力埧的自振特性,通过实驗进行了比較。
This paper conducts preliminary theoretical analysis and experimental research on the natural vibration characteristics of the gravity enthalpy (hollow gravity enthalpy) of the Raney-type hydropower station. According to the principle of energy law, the theoretical calculation formula of the first free-running frequency of the gravity enthalpy of the Raney-type hydropower station is derived, and verified by the model test, the theory and experiment are basically consistent. This paper also compares the natural vibration characteristics of the hollow gravity enthalpy and the solid gravity enthalpy of the Yannai-type hydropower station through experiments.
