潮流能水轮机叶片实验原型快速制造方法研究

Rapid Manufacture Method for Tidal Stream Turbine Blade Testing Model

提出了采用三维CAD、反求技术和快速原型(rapid prototyping,RP)技术快速制造海洋潮流能开发利用的获能装置——潮流能水轮机叶片原型的方法。应用该方法制作了实验模型进行实验,结果显示,对比已有铸造模型水轮机,采用快速成形方法制造的模型在结构强度、精度上都能满足实验要求,并且可以通过模型实验对该方法建立的不同翼型水轮机进行优化选型。

A rapid manufacture method for blade of tidal stream turbine which is the energy capture device in exploitation of tidal stream energy was put forward using CAD, reverse technology and rapid prototyping technology. Testing models were manufactured using this method. Results show that models manufactured by RP technology can meet the requirements of hydrodynamics testing both on structure strength and precision, compared with the casting turbine models. And the models with different vane shades manufactured by RP technology can be optimized by model testing.
