Hi, excuse my bad English.
I would give me your opinion on an issue: I want to model one quarter of vehicle. The tire manufacturer provides Kz (vertical tire stiffness) for different pressures and camber angles, but does so for a given speed (125 Kph).
Kz varies linearly with speed (something like: Kz=a*V+b, b>0) and Kz increases if the speed is increased (a>0) but what I can know how much ¿? There any way to make a rough estimate. Knowing the type of tire, size or something else might be able to determine about this variation? I wonder if there is any way of knowing about what is the slope of that line knowing, for example, the dimensions of the tire or the type of tire (radial).
If the graphics are deflecction (m.m) vs. Load (Kg), is not entirely correct to obtain the vertical tire stiffness of calculating the slope of the line (Load*9.81/deflecction). The force that causes a certain deflection is the weight + the effect of centripetal force, not just weight. What do you think about this
Thank you very much
