Create a constant acceleration motion

Create a constant acceleration motion

Create a constant acceleration motion

(OP)
Hello,

I am trying to recreate a rotor shaft model in order to find the natural frequencies. However, I want to model this rotor kit as if it was attached to a motor which is why I want to use a constant acceleration motion. How can I input this as a function?

RE: Create a constant acceleration motion

You don't say which package you are using. In Solver language you want something like

JOINT/201, REVOLUTE, I=2011, J=2013
MOTION/201, JOINT=201, FUNCTION=5*TIME*TIME

Which should give you an acceleration of 10 degrees or radians /sec/sec

You can build this in the function builder in View, hopefully (I don't use View)

Cheers

Greg Locock
