算例： 1 正常发电工况： - 均匀风 - 没有变桨、偏航、转速调整 对比结果 功率、叶片变形量、什么什么载荷？ q 叶片、塔架的振型如何看？ 风速 8m/s 转速不知 1、Bladed、FAST 15MW模型直接对比结果 2、V0.5软件与fast 15mw对比 3、气动改用AeroDyn ED对比 V4.0 vs V3.5 新增 .fst - seast ElastoDyn - 增加ptfmxyIner - 增加YAW-FRICTION AD 15 - 删去 AFAeroMod - 删去 FrozenWake - 增加NacelleDrag - 增加BEM_Mod 潜在问题： 1 刚度、模态曲线是否一致 bladed 模态振型导出 bladed 模态与fast一致后，计算结果如何 2 气动结果差异 ## 测试过程 - 采用v3.5气动数据情况下，多体计算结果与FAST一致 - 采用v4.0气动数据情况下，多体计算结果与FAST一致 fast bladed 载荷对比 叶片载荷 | fast | | | | | ------------- | ---------------------------------------------------- | --------------------------------- | ------ | | Spn1MLxb1 | Blade 1 local edgewise moment at span station 1 | About the local xb1-axis | (kN-m) | | Spn1MLyb1 | Blade 1 local flapwise moment at span station 1 | About the local yb1-axis | (kN-m) | | Spn1MLzb1 | Blade 1 local pitching moment at span station 1 | About the local zb1-axis | (kN-m) | | | | | | | Spn1FLxb1 | Blade 1 local flapwise shear force at span station 1 | Directed along the local xb1-axis | (kN) | | Spn1FLyb1 | Blade 1 local edgewise shear force at span station 1 | Directed along the local yb1-axis | (kN) | | Spn1FLzb1 | Blade 1 local axial force at span station 1 | Directed along the local zb1-axis | (kN) | | | | | | | bladed | | | | | Bladed 1 Mx | Principal axes | | (N-m) | | Bladed 1 My | Principal axes | | (N-m) | | Bladed 1 Mxyz | Principal axes | | (N-m) | | | | | | | Bladed 1 Fx | Principal axes | | (kN) | | Bladed 1 Fy | Principal axes | | (kN) | | Bladed 1 Fxyz | Principal axes | | (kN) |
