## bladed开发计划与进展
|
||
|
||
|
||
### turbine challenges
|
||
|
||
- growth
|
||
- challenge in structures aerodynamics stabilities
|
||
- 固定式 - 行架式 - floating
|
||
- 计算数增加,时间增长、工况复杂
|
||
- 浮式平台多种形式
|
||
|
||
### bladed4
|
||
100+ industrial customers
|
||
|
||
long flexible blades
|
||
|
||
|
||
|
||
|
||
### deep stall
|
||
|
||
叶片的高频振动,instability
|
||
|
||
SIV-1 stall induced vibration
|
||
攻角在-150-150,也会引起vibration SIV-2 ,存在两个问题 :1没有气动数据,没有unsteady 模型
|
||
|
||
|
||
IAG dynamic stall model
|
||
|
||
IAG在Cl Cd Cm上都更准确 13%,21%, 24%厚度
|
||
|
||
IEA 15MW DLC 6.3
|
||
BEM + no DS BEM + BL model 都出现叶片抖动
|
||
BEM + IAG model 不抖动,但是也出现停顿
|
||
|
||
|
||
|
||
|
||
### bladed5
|
||
|
||
flexible turbine assembly tree
|
||
superelement ()
|
||
|
||
model imbalance
|
||
- add 模块之间的offset
|
||
|
||
|
||
better support of early blade design process
|
||
independent meshes between aerodynamic and structure
|
||
|
||
基于api前处理和后处理
|
||
|
||
|
||
### bladed 5 new features
|
||
|
||
- yaw bear model
|
||
|
||
- add sensors to simulation
|
||
