Hello Eng-tips experts. Is there a short answer to why increasing axle stiffness at one axle will create more slip at that axle relative to the other axle? This question is related to how to get more oversteer/understeer ie suspension tuning/roll bar tuning.. Thanks!
Hello eng-tips experts. I'm using 3D rigid body dynamics software to model a few car designs. I wanted to check a fairly simple concept in transient state,
How camber affects overturning and slide out(loss of traction):
- M*a_y acts on CM to start lateral load transfer to outside tires
-...
Hello eng-tips. For vehicle suspension/dynamics design, how can I relate the concepts of flat ride and center of percussion?
Discusses COP at the rear axle:
Shows the bounce center, Olley:
Also, I need to get a Milliken or Gillespie book, which would be better suited for off-road dynamics?
Hello eng-tips experts. For starters: I have a complete, fairly high fidelity, RBD simulation model of an off-road race vehicle, in Maplesim. Currently the model sits with IFS and a rear 4-link, triple bypass and dual rate coilovers on ea corner, real Modelon fluid flows. After a month or so...
Will a vehicle rotate around its sprung center of mass while turning? I’m trying to nail down, without CAD, my inertia tensors for components like engine, body, fuel, in rigid body dynamics software. Something is telling me tire loads need to be considered.. thx
(EDIT: considering global and...
Hello. I'm working on modeling a coil spring in my Advanced Systems Modeling software. There is a damping constant value that needs to be set so that the spring will stop oscillating at some t.
(heres info on damping ratio https://en.wikipedia.org/wiki/Damping_ratio)
Suppose we take a...
