【摘要】：當(dāng)前風(fēng)機(jī)葉片模塊設(shè)計(jì)過程復(fù)雜,性能低下,為此設(shè)計(jì)激光數(shù)控加工逆向工程風(fēng)機(jī)葉片模塊。通過簡(jiǎn)化設(shè)計(jì)方法對(duì)外形設(shè)計(jì)的基本參數(shù)進(jìn)行確定,獲取風(fēng)速和相應(yīng)參數(shù)之間的關(guān)系,依據(jù)風(fēng)機(jī)葉片結(jié)構(gòu)要求,通過葛勞渥方法完成初步的氣動(dòng)性能分析與調(diào)整,實(shí)現(xiàn)激光數(shù)控加工逆向工程風(fēng)機(jī)葉片模塊外形的設(shè)計(jì)。確定葉片的初始參數(shù),令風(fēng)機(jī)葉片各截面葉素的輸出功率最大。實(shí)驗(yàn)結(jié)果表明,所設(shè)計(jì)風(fēng)機(jī)葉片模塊壓力分布均勻,升力高,滿足設(shè)計(jì)要求。
[Abstract]:At present, the design process of fan blade module is complicated and the performance is low. For this reason, laser numerical control machining fan blade module is designed. The basic parameters of shape design are determined by simplified design method. The relationship between the wind speed and the corresponding parameters is obtained. According to the structural requirements of the fan blade, the preliminary aerodynamic performance analysis and adjustment are completed by the Grawwood method. The design of the shape of the blade module of reverse engineering fan is realized by laser NC machining. The initial parameters of the blade are determined, and the output power of the blade element of each section of the fan blade is maximum. The experimental results show that the pressure distribution of the fan blade module is uniform. High lift to meet the design requirements.
