摘要
垂直轴风力机相对于水平轴风力机而言具有诸多优点.基于轮轨式垂直轴风力机工作原理,进行总体结构设计.车轮发电平台是轮轨式垂直轴风力中的重要部件,主要起发电和转向作用.设计一种车轮直接带动各小型发电机的分布式车轮发电平台结构,使驱动发电机转动的车轮始终与发电机处于同一个摆动平台.该车轮发电平台可随着运行轨道曲率变化而不断自适应地转动,具有各发电机机械转动能被平稳输入的优点.设计防倾覆装置安装于风力发电小车底板上,可调整其与轨道之间的间隙,保证风力机运行时不发生倾覆.运用有限元技术对车轮发电平台受力关键零件进行静力学强度分析,验证设计的结构满足强度要求.
Compared with horizontal axis wind turbine,vertical axis wind turbine has many advantages.Based on the working principle of wheel rail vertical axis wind turbine,the overall structure design is carried out.Wheel power generation platform is an important part of wheel rail type vertical axis wind power,which mainly plays the role of power generation and steering.A distributed wheel power generation platform structure is designed,in which the wheel directly drives each small generator,so that the wheel driving the generator to rotate is always on the same swing platform with the generator.The wheel generator platform can rotate adaptively with the change of the curvature of the running track,and has the advantage that the mechanical rotation energy of each generator can be input smoothly.The anti-overturning device is designed to be installed on the bottom plate of the trolley,which can adjust the effective clearance between the device and the track to ensure that the wind turbine will not overturn during the operation.The static strength analysis of the key parts of the bogie is carried out by using the finite element technology to verify that the designed structure meets the strength requirements.
