  Hi , I've been working on a reaserch, however am facing problem with the application of a cyclic loads on ANSYS. I am a beginner in ANSYS I appreciate any help
  
  thank you .

  hello thabtisalma
  
  what module you are using in static structure.
  
  when you click the force or moment
  
  there is option for 1) constant load
  
  2) tabular load
  
  3) function you can provide F=10*sin(w*time)

  Are you trying to analyze the structure for fatigue failure?
  
  Or are you trying to analyze the dynamic response of the structure to a periodic forcing function?

  i want to analyse the structure for fatigue failure and study the lifetime of wind turbine blade

  Read this post about the Fatigue Tool that is included in ANSYS.
  
  You want to be able to load the wind turbine blade in the extreme loads. Is the load always between zero and a positive deflection, or does the blade vibrate between positive and negative deflections?

  So if you apply the maximum load of 500 from your graph, and the minimum load is zero, that is a Ratio of 0 and you can put that in the Fatigue Tool to estimate life if you have the fatigue properties for the material in Engineering Data.
