摘要
当前风机叶片模块设计过程复杂,性能低下,为此设计激光数控加工逆向工程风机叶片模块。通过简化设计方法对外形设计的基本参数进行确定,获取风速和相应参数之间的关系,依据风机叶片结构要求,通过葛劳渥方法完成初步的气动性能分析与调整,实现激光数控加工逆向工程风机叶片模块外形的设计。确定叶片的初始参数,令风机叶片各截面叶素的输出功率最大。实验结果表明,所设计风机叶片模块压力分布均匀,升力高,满足设计要求。
Fan blades module design process is complex and in poor performance. Therefore,we design a new laser NC fan blade reverse engineering module. Simplified design method for shape design to determine the basic parameters,and obtain the relationship between the wind speed and corresponding parameters. According to the requirements of fan blades structure,complete a preliminary analysis of the aerodynamic performance and adjustment through Glauert method. Secure the output power is the largest in each section of the fan blades. The experimental results show that the design of fan blades module uniformed the pressure distribution,has high lift and can meet the design requirements.
