bladed軟件學(xué)習(xí)筆記

1、近來(lái)學(xué)習(xí)一下bladed軟件，版本號(hào)為3.81。在此做做學(xué)習(xí)筆記吧，如碰到同道 中人，也可以討論共勉。Bladed的功能就不說(shuō)了，簡(jiǎn)要記下基本界面的組成。GH Bladed軟件主界面如下圖所示：主要的設(shè)置和計(jì)算功能分為13個(gè)部分。除后三項(xiàng)為計(jì)算分析相關(guān)外，均為參數(shù)設(shè)置部分。參數(shù)設(shè)置又分為風(fēng)機(jī)參數(shù)（前 8項(xiàng)）和外部環(huán)境參數(shù)（Wind, SeaState）二部分。軟件的基本工作流程：通過調(diào)用、自定義或修改模型參數(shù)后，通過計(jì)算選項(xiàng) 選擇計(jì)算內(nèi)容計(jì)算，后通過數(shù)據(jù)觀察分析功能查看計(jì)算結(jié)果并進(jìn)行數(shù)據(jù)處理。選項(xiàng) 1: BladesBlades主要定義葉片的外部幾何尺寸，重量分布及剛度。主要的參數(shù)有：長(zhǎng) 度、

2、弦長(zhǎng)（各剖面）、扭角、厚度、質(zhì)量因素和剛度因素。Blade Planform; iZhord, Pil :h axis CbLack axic （叮曰雪門入 m臺(tái)已靠弓m hrtd）Fta-diug （irj9 口即利 Slilfr ptt as Log GraphG-uph jArfcmarEApplOKCineol選項(xiàng) 2： AerofoilAerofoil定義了葉片翼型，并可通過對(duì)翼型的定義，確定任意攻角下也葉片 氣動(dòng)系數(shù)（升力系數(shù)，阻力系數(shù)等）Blades和Aerofoil兩個(gè)選項(xiàng)共同定義了全部的葉片參數(shù)。葉片的性能主要 依賴于翼型、弦長(zhǎng)和扭角分布這幾個(gè)關(guān)鍵參數(shù)。Name demons
