Sure, but it's vacation time and I don't have any way to join him, that's why I'm asking here actually. Note : we haven't seen anything about the physics of deformable materials and surfaces.

Hi there! First of all, I do not have a clear homework statement or relevant equations to give but I still put this thread in here because it's related to school work and I've previously got a warning for not doing so. I'm a french student who is going to start his second year after high school...

Thanks to all of you, I now have my results right I do not see where to close the topic, so I'll let it like that (maybe I'll come back for a further step)

Oops That doesn't change anything actually

No I followed @jack action and saif

You both said the same thing, and yes, my bad, that's a misspelled variable Yes, I know, but because I will add other forces later, I keep it here for consistency I will admit front and rear brakes are the same, I don't want to bother myself with drum brakes I will multiply the pressure by...

I strongly agree with all of this All my numbers are in SI units, so kilograms, meters... Yes my car is very tiny, even by France standards Okay, that's the first source of error, I supposed the caliper to be put on the outside of the rim, and it seems very true that it's not realistic this...

Okay then If I input a pressure greater than 5 bar I always have the same graph because the tire slip Here with 50 bar With 5 bar and less I have : For 5 bar : For 4 bar : For 7 bar : For any value greater or equal to 7, the graph is exactly the same yes, it was 6, not 5, but that's not...

I think I will stop this topic after your answers about that, try to refocus, and refactorize my project a bit. I may come back in a new thread later for other questions, but I think we have already been too far from the initial subject of this thread.

I don't want to design any braking system, I only want to quickly model how the brakes make the car running decelerate, given as few inputs as possible. EDIT : I am realizing just now that, because I'm in an emergency braking case, the brakes are supposed to be at their maximum capacities, so...

These numbers are found by that (in loop): couple_freins = -2 * (pression_freins * surface_plaquette) * (rayon_frein / rayon_pneu) limite_glissement = -mu_sol * masse * g if abs(couple_freins) > abs(limite_glissement): F_eq = limite_glissement else: F_eq = couple_freins M_eq = masse...

For this force, I only want to take an approximation of reality, it's not the main point of my study. I would be happy with a bare approximation (if online data says 60 to 100 bar I would be quite happy with 80) It's just that 5 bars is not quite the same as 50 bars

Found online : I will call ##P_{bl}## the pressure in the brake line and ##S_{bp}## the surface area of the piston Question 1 : isn't the area of the piston = the area of one pad ? Then, I have ##F_B = 2 * P_{bl} * S_{bp}## I have to mention here that it's exactly what is was doing before but...

I haven't done any calculation for the pressure on the pads as until now, I was mistaken and assumed the pressure in brake lines is the same as the pressure of the pads on the disc. Now, I will have to calculate the pressure of the pads on the disc from the one in the brake line... Sorry for...

Okay, So the pressure in the brake line is not the one of the pad on the disc the There must be some "conversion" unit that makes the pressure on the pads so low
