摘要

为了探索一套分析升阻组合式垂直轴风力机(LD-VAWT)结构的方法，根据相应的标准和小型垂直轴风力机通用设计要求，设计了小型LD-VAWT。采用有限元方法对一种小型LD-VAWT主要部件的静力性能和模态进行了计算和分析。得到了相应的应力和位移轮廓，并得到了主要零件的一阶六阶振型振动轮廓。结果表明，在额定转速工况下，LD-VAWT的主要结构部件满足设计要求。此外，在模拟中，所有主要部件在运行过程中均未发生共振。根据本研究的分析和仿真结果，制作了LD-VAWT样机，并稳定运行。所采用的方法可为垂直轴风力机的静力学性能和模态分析提供参考。

Static Mechanical Properties and Modal Analysis of a Kind of Lift-Drag Combined-Type Vertical Axis Wind Turbine

In order to explore a set of methods to analyze the structure of Lift-Drag Combined-Type Vertical Axis Wind Turbine (LD-VAWT), a small LD-VAWT was designed according to the corresponding Standards and General Design Requirements for small vertical axis wind turbines. The finite element method was used to calculate and analyze the static mechanical properties and modalities of main parts of a kind of small-scale LD-VAWT. The contours of corresponding stress and displacement were obtained, and first six-order mode vibration profiles of main parts were also obtained. The results show that the main structure parts of LD-VAWT meet the design requirements in the working condition of the rated speed. Furthermore, the resonances of all main parts did not occur during operation in the simulations. The prototype LD-VAWT was made based on the analysis and simulation results in this study and operated steadily. The methods used in this study can be used as a reference for the static mechanical properties and modal analysis of vertical axis wind turbine.

期刊介绍： This comprehensive journal provides the latest information on rotating machines and machine elements. This technology has become essential to many industrial processes, including gas-, steam-, water-, or wind-driven turbines at power generation systems, and in food processing, automobile and airplane engines, heating, refrigeration, air conditioning, and chemical or petroleum refining. In spite of the importance of rotating machinery and the huge financial resources involved in the industry, only a few publications distribute research and development information on the prime movers. This journal is the first source to combine the technology, as it applies to all of these specialties, previously scattered throughout literature.
