Cars in beamng don't have bump stops. All cars that I know in real life have bump stops. Will bump stops be added to cars in a future update?
Pretty sure they have physically simulated ones, just no visual models for them. They aren't really needed anyway as most of the suspension doesn't collide with the chassis.
yeah maybe no visuals. But the cars scrape the floor before the suspension stops traveling. --- Post updated --- Doesn't seem like it as cars scrape their bottom before the suspension stops compressing.
They don't stop it 100% after huge jumps, they are not made for extreme stuff. Have you even tested it with normal realistic conditions (bumpy roads and stuff)?
Take this example. This here is in the Vivace's base strut jbeam. You can clearly read that the comments (aka //) document a bump stop implementation. And yet:
Well... remember... on really hard hits, your also compressing the tires along with the suspension. This can cause you to bottom the car out even on flat ground if you compress the tires far enough. Bump stops or not, there's always a way to bottom out a car. Besides... while bump stops are partially to help with keeping a vehicle from bottoming out... what their main purpose is is to keep a vehicle from acquiring drivetrain, suspension, steering, or frame/unibody damage due to angles in components that they just weren't designed to handle. Mostly it has to do with driveshaft angles and shock/spring travel limits, but axles slamming into frame rails doesn't help either.
ik they don't help jumps but normal things seem to also behave is if the car has no bumpstops --- Post updated --- yup but I inflated the tires to 50 psi so there's like no tire compression and it still bottoms out
50 PSI is still far from "no tire compression" on some tires. If you could somehow increase the range to a massive value where the tires become solid and almost explode, then it might work, but the game doesn't let you go THAT far.
Remember... Like I said... while most times they do play a roll... they don't always stop the car from bottoming out... As you can see how low that side is compressed there? Even only an inch off the ground, he's not on the bump stops yet. You compress both sides that low you may as well be sitting on the oil pan.
Beamng already has bump stops, though they could be more polished in some regards. In real cars however, bump stops aren't hit very often, they're not being hit even if the car bottoms out on the ground, to allow the suspension to travel. fully. because car usually handle unpredictably when bump stop is to close to being reached or hit. It's really more of a redundancy to ensure the car doesn't break itself upon extreme impacts too hard. Bump stops also vary from car to car. If a car is hitting bump stops then it's by a bad suspension design and/or wear. Would be useful to know which car you personally experienced a bump stop event in, if at all.
Pretty much the only car I have ever hit the bump stops on is my Honda Beat. But that was in a left hand 90 degree corner going downhill into an uphill at about 40mph. But that is a very tiny car with a big heavy dude being pushed really hard. Like that was way beyond what it should have been subjected to. No other car have I ever managed to do it in.
bump stops are more noticeable in cars with higher and softer suspension, my India spec Renault Logan has bottomed out a few times, hitting the skidplate under the engine once too, and the bump stops are also noticeable when going over road undulations at highway speeds with a car full of passengers.....
that is a terribly designed suspension. Full load of cargo on highway should not result in such cheap behavior
It is a cheap car. I wouldn't expect any less. And it's the Logan mk1 from 2009, McPherson struts in the front and Torsion Bar on the rear..
Actually bump stops are part of spring system doing lot more than just stopping damage to suspension parts. When vehicle is at rest, you might already touch the bumpstops, which are quite progressive springs, but are used to add spring rate for cornering. In BeamNG there are bump stops, but for me they appear bit lacking in self damping properties as sometimes you get launched up into air because of them, one end of car kinda hops from certain kind of bumps, while in reality especially rubber bumpstops tend to have quite bit of damping build in them. This article gives quite ok primer for other functions of bump stops: https://www.motortrend.com/how-to/modp-1104-the-bump-stops-here/ When building vehicles in BeamNG, we have really good possibilities to use bumpstops to perfect the handling.
