I need to calculate the natural frequency of a 19mm Dia x 1.6wall x 720mm long Fibreglass Tube. I am trying to calculate the critical speed of of this member as it is developing vibrations at around 80km/h (wind speed). I would to see if the critical speed is close to this 80km/h.
If it is I will need to see what can be done to design out this problem, ie increase thickness, stiffness, length etc dampening etc...
