N Freedom Vibration Model

This applet can imitate a N freedom vibration model. You can used it to see the relations between  model parmeters and the modal parmeters. And you can used to imitate the vibration outputs on a certain excite  force.

Operation Steps
1. Input the freedom of model: N
2. Input the model parmeters: Mi, Ci, Ki,  i=1,2,....,N
3. Press "Get" to compute the modal parmeters
4. Select a excite point,
5. Select type of excite force,
6. Show the output in a certain point,
7. Show the transfer function in a certain point.
