Hi,

I am trying to perform a sine sweep analysis with a sweep rate of 4 oct/min. I have already done the modal analysis but I'm not sure how to setup the harmonic analysis with the sine sweep rate. I have the following test profile:

3.84 in./s - 5-24 Hz

1.53g - 24-100Hz

3.50g - 110-800Hz

10.0g - 800-2000Hz

Thrust Axis Only

Thank you for your help!

There isn't a sine-sweep analysis type in Ansys or even an easy way to specify harmonic acceleration vs frequency.  Each frequency range would be a separate harmonic analysis over that frequency range and the response would not take into account the sweep rate.
