  Hi, I have a table of acceleration with frequency for sine vibration simulation... but there is a requirement that the table is for Q factor more than 15.
  May I know how does the Q factor affect the input for harmonic simulation? Thank you!

  For a damped harmonic oscillator, the measure of dampness an oscillator is is defined by the Q factor or Quality Factor (Q factor - Wikipedia). It is a dimensionless parameter.
  Higher Q indicates a lower rate of energy loss and the oscillations die out more slowly. A pendulum suspended from a high-quality bearing, oscillating in air, has a high Q, while a pendulum immersed in oil has a low one. Resonators with high-quality factors have low damping so that they ring or vibrate longer.

  thanks for your reply.
  So, if I change the input of damping ratio, it would change the Q factor, right?
  Thanks!

  Yes, it should.
