Renewable energy resources are becoming more important to meet growing energy demands while reducing pollutants in the environment. In the current market, wind turbines are primarily restricted to rural use due to the large size, noise creation, and physical appearance. However, wind turbines possess the ability to run at any time of the day. Horizontal axis wind turbines remain the most widely used, but there is significant room for improvement in vertical axis wind turbines. While vertical axis wind turbines are not reaching the same level of efficiency of horizontal axis wind turbines, there are significant benefits to researching improvements. One of the main benefits is to make use of vertical axis wind turbines in urban settings. In order to improve the efficiency of the vertical axis wind turbine, a biological approach was taken to design blades that mimic the shape of maple seeds and triplaris samara seeds. This approach was taken because due to its geometrical properties, typically extra lift is generated. The results obtained through FEA simulations were consistent with the expected results for the application that was considered. The results obtained provide valuable insight for engineers to iterate and design optimum wind turbine blades taking advantage of biological phenomena applied to conventional airfoils. The purpose of this paper is to provide structural analysis details into the design of a vertical axis wind turbine blades that mimic the geometry of maple and triplaris samaras seeds.

生物启发的小型风力涡轮机叶片的结构分析

可再生能源在满足不断增长的能源需求的同时，减少环境中的污染物变得越来越重要。在当前市场中，由于大尺寸，噪声产生和外观，风力涡轮机主要限于农村使用。但是，风力涡轮机具有一天中任何时候运行的能力。水平轴风力涡轮机仍然是最广泛使用的，但是垂直轴风力涡轮机还有很大的改进空间。尽管垂直轴风力涡轮机的效率未达到水平轴风力涡轮机的同等水平，但是研究改进具有明显的好处。主要优点之一是在城市环境中使用垂直轴风力涡轮机。为了提高垂直轴风力发电机的效率，采用生物学方法来设计叶片，该叶片模仿了枫树种子和三叶草种子的形状。之所以采用这种方法，是因为由于其几何特性，通常会产生额外的升力。通过FEA仿真获得的结果与所考虑的应用程序的预期结果一致。获得的结果为工程师利用传统机翼上的生物现象进行迭代和设计最佳风力涡轮机叶片提供了宝贵的见识。本文的目的是在模拟枫木和三叶草种子几何形状的垂直轴风力涡轮机叶片的设计中提供结构分析细节。通常会产生额外的提升。通过FEA仿真获得的结果与所考虑的应用程序的预期结果一致。获得的结果为工程师利用传统机翼上的生物现象进行迭代和设计最佳风力涡轮机叶片提供了宝贵的见识。本文的目的是在模拟枫木和三叶草种子几何形状的垂直轴风力涡轮机叶片的设计中提供结构分析细节。通常会产生额外的提升。通过FEA仿真获得的结果与所考虑的应用程序的预期结果一致。获得的结果为工程师利用传统机翼上的生物现象进行迭代和设计最佳风力涡轮机叶片提供了宝贵的见识。本文的目的是在模拟枫木和三叶草种子几何形状的垂直轴风力涡轮机叶片的设计中提供结构分析细节。获得的结果为工程师利用传统机翼上的生物现象进行迭代和设计最佳风力涡轮机叶片提供了宝贵的见识。本文的目的是在模拟枫木和三叶草种子几何形状的垂直轴风力涡轮机叶片的设计中提供结构分析细节。获得的结果为工程师利用传统机翼上的生物现象进行迭代和设计最佳风力涡轮机叶片提供了宝贵的见识。本文的目的是在模拟枫木和三叶草种子几何形状的垂直轴风力涡轮机叶片的设计中提供结构分析细节。
