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
