Simulink model of Active Suspension

[Jones1987]

Hi, I've created the model for an active suspension, however my suspension working space, body accel and tyre load graphs, I'm not sure if they're correct.

If anyone could look at the model and tell me if I have gone wrong, I'd be grateful.

Thanks.

Values:
ks = 22000
kt = 192000
cs = 1500
mw = 45.5
mb = 350

to me the model looks passive as there is no controller input, just the road disturbance input. easier is to create equation models for a quarter car and get some matrix inputs and try it that way. what is your project about?

Hi,

It's a lab practice paper I requested, for an upcoming assignment. I just want the effects of the suspension from its ground input. My bad I shouldn't have really called it 'Active Suspension'.

I have created and played with this setup in Matlab, but Simulink is a whole different area for me. From what I can see, the setup seems right from the EOM. I'm just not sure if the Body accel and SWS scopes are in the right position, and if they are, are the results I'm obtaining correct?
