7、的目的是設(shè)計一種簡單的成本較低同時效率較高的垂直軸攻角可變的風(fēng)力發(fā)電機(jī)，嘗試通過利用計算機(jī)輔助設(shè)計和分析，減少項目開發(fā)的成本和時間。1.1風(fēng)力發(fā)電現(xiàn)狀介紹現(xiàn)在風(fēng)力發(fā)電應(yīng)用還是比較多的，有很多大型的風(fēng)電場，風(fēng)力發(fā)電是一種制作比較簡單，制作成本和維護(hù)成本較高的發(fā)電方式，它的優(yōu)點是綠色環(huán)保，理想的綠色能源。目前主流風(fēng)輪有三種：14青島理工大學(xué)大學(xué)生科技創(chuàng)新項目右圖是水平軸大型風(fēng)力發(fā)電機(jī)，翼型的扇葉有效提高風(fēng)能利用效率，主要用于大型風(fēng)電場，常年風(fēng)力較大而且風(fēng)向不變，這種風(fēng)力發(fā)電機(jī)效率較高維護(hù)成本低。右圖是一種比較常見的垂直
8、軸升力型風(fēng)力發(fā)電機(jī)，適合家庭使用，需要風(fēng)力較大，風(fēng)速高時效率是最高的，結(jié)構(gòu)簡單維護(hù)成本低，低風(fēng)速時優(yōu)勢不明顯，翼型加工較困難。總的來說是非常好的設(shè)計。右圖是垂直軸阻力型風(fēng)力發(fā)電機(jī)，結(jié)構(gòu)簡單制作容易而且維護(hù)成本低，缺點是效率較低，弧面回程時受阻力，降低了風(fēng)輪的風(fēng)能利用率。1.1各種創(chuàng)新型風(fēng)力發(fā)電在尾部裝上對風(fēng)裝置的水平軸發(fā)電機(jī)也有非常高的效率，但它也有自己的缺
