Research on Theoretical Calculation Method of Natural Frequency of the Pendulum Wave Power Conversion Device

研究摆式波浪能转换装置固有圆频率的理论计算方法,主要探讨了船舶振动计算模型、铰接塔平台计算模型、纵摇体计算模型。通过理论计算得到不同方法下的固有圆频率,同时为了验证理论计算的正确和合理性,进行了水槽模拟试验,确定铰接塔平台计算模型是一种最佳的固有圆频率理论计算模型,为以后摆板设计提供重要依据。

Three calculation models are used to study on theoretical calculation method of the natural frequency of the pendulum wave energy conversion device,including the calculation model of ship vibration,the calculation model of articulated tower platform and the calculation model of pitch motion.Three natural frequencies are gotten using these three calculation models.Flume experiment is adopted to verify which results is right.Verification results demonstrate that the calculation model of articulated tower platform can be applied to calculate the natural frequency,which provides an important basis to the design of the pendulum system.
