following questions
how to analysis fixed botton wind turbine ?
how to consider TMDI effect during analysis under wind and seismic load in turbsim or seismic module ?

Dear @Muhammad.Irfan,

Just a few comments:

  • The Seismic functionality of FAST v7 has not yet been migrated over to FAST v8 or OpenFAST.
  • The Structural Control (TMD) functionality is available in FAST v8 and OpenFAST, but not in FAST v7
  • The version of FAST v7 that supports Seismic functionality can consider a fixed-bottom monopile; FAST v8 and OpenFAST can consider other fixed-bottom offshore systems like tripods and jackets.

Best regards,

Mr jason thanks for your reply
i have some more questions regarding fixed botton ,it is not possible if we do not consider monopile or triople either jackets to check the seismic behaviour of wind turbine tower with nacelle?

4

can we also consider mechanical inerter or fluid inerter mechanism with TMD in fast or openfast to minimize the vibration of the wind turbine ?

Dear @Muhammad.Irfan,

I’m not sure I understand your question about fixed-bottom systems; please clarify.

The Structural Control (StC) submodel of ServoDyn within OpenFAST considers tuned-mass dampers (TMDs) and tuned liquid column dampers (TLCD). I’m not familiar with the details of how these differ from inerters, but inerters are not directly considered within StC. See the StC documentation for more information: 4.2.12. Structural Control (SrvD) — OpenFAST v3.5.1 documentation.

Best regards,

thanks sir for making clear about all this
