pitch center measurment

pitch center measurment

(OP)
Hi all,

I have a simple vehicle multibody model and I need to identificate some parameters from measurments on a real vehicle. I need to know the pitch center. How could I measure the pich center position? I'm thinking to use a 6dof inertial platform but I don't know how to accomplish it.

Thanks!

RE: pitch center measurment

First define what you mean by pitch centre. If you mean, for example, the approximate point about which the vehicle pivots when going over small bumps at a given speed, then just use your platform to identify the point with zero z translation during the event.

 

Cheers

Hi Greg,

thanks for your prompt reply. The pitch center I mean is the one you described. Unfortunately I don't have any platform, I can just drive the vehicle on the road. Is anything I could for estimating it on road driving?

Cheers

Pietro
