I think that vehicles should be more prone to flipping in beamng. For example, the ford explorer would flip if you swerved on the highway, or just tapped it while at high speed. In slalom tests, large vehicles go onto two wheels. The roamer is very hard to flip.
The Roamer is hard to flip because cars tend to be somewhat difficult to flip. The first/second gen Explorer was a bit of an exception due to the rear track width not being wide enough to accommodate the higher center of gravity on an SUV, since it basically used Ranger suspension parts. The Roamer has a wider track width due to it being a full-size SUV rather than a mid-size like the Explorer, and it is in turn harder to flip. The Roamer is still fairly tip-happy if you're on a bumpy road, but if any car can manage to flip on a perfectly flat surface then that is definitely unrealistic. If you want a Roamer that you can easily flip, then mess with crank up tire friction and ride height, add some more weight to the roof, and soften the suspension.
Not every car is supposed to flip that easily and i know that. And isnt the roamer based on an exlporer? Its not about hollywood stuff, its real life. Did you see that road rage video with the biker, the honda accord, and the chevy avalanche? The accord driver hits the rear quarter panel of the avalanche, and it slides, then just goes over and over.
The Roamer isn't based on anything in particular, but it's closest to the Ford Expedition, Chevy Tahoe, and GMC Yukon in terms of its class. The Roamer is full-size, the Explorer is mid-size. First of all, it was an Sentra and an Escalade EXT. Secondly, if you recreated that crash with the Roamer (or any other top-heavy vehicle), it would likely behave in a very similar way. That crash was way different than a sharp turn or a slalom.
http://igcd.net/game.php?id=1000010344 This site shows what cars the beamng cars are based off of. The shorter roamer is an explorer. I also raised the roamer, decreased the track width, gave it positive camber, and bigger tires. It still would not roll, even though it was lifting a wheel.
Why're you using off-road tires? Those tires have even less contact to the pavement than normal road tires, try using grippier tires.
It's not an explorer, that site is a third party site and can say whatever they want. In terms of weight, IIRC it's inbetween the Explorer and Expedition.
I've just made a much cleaner looking config using the 2x4 Roamer XT. I've removed all sway bars, rear shock absorbers & installed lifted Roamer coilovers. I'm not sure what the difference is from normal lifted ones to the Roamer specific. For wheels I chose the Okudai PR02 wheels with racing tires installed but I'm pretty sure any wheel is good as long as race or grip-all compounds are installed. Note that I lowered air pressure in the tires but that might not be necessary
weird. I've been doing research, and it turns out it was tire blowouts that caused rollovers in ford explorers, so I think the tire pressure is the cause. --- Post updated --- Removing the shocks, slightly lifting and stiffining it, removing the swaybars and decreasing tire pressure is enough to get it onto two wheels, and if you slide it, it will start to hop then flip
I read this last night and did a bit of experimenting. It's definitely possible to roll the Roamer without changing tire compound. Reducing track width, removing sway bar, stiffening rear suspension, lowering tire PSI, and slightly increasing center of gravity by adding some weights to simulate the shitty explorer definitely makes it a bit sketchy on the runway on JRI.
Removing the shocks, slightly lifting it, removing the swaybars and decreasing t thats exactly what i did, and it rolls very easy, without help from other cars.
Another thing to take into account, not only did the Explorers have a bad batch of tires that caused blowouts from people panicking and not keeping the thing going correctly, but that range of Explorers, like mentioned, used all ranger parts including front twin I Beam suspension. Front twin I Beam suspension causes massive wheel camber changes with wheel travel. This coupled with a ton of grip from soft front sway bars designed for off road use meant that the Explorer was just a bit wobbly... but steered aggressively enough (which it wasn't designed for) would end up with a roll over. The Roamer, on the other hand, I believe uses twin A arm front suspension. This allows for much more control of weight transfer in the vehicle than a twin I Beam does. If you went and slapped some twin I Beams on the Roamer... I bet you would get pretty close (or at least much closer) to the wobbliness you are looking for.
In general, one thing that BeamNG cannot properly simulate is that in real life when a vehicle lands sideways on loose ground it will dig in somewhat... greatly raising tyre resistance and as such brake force and as such the tendency of the upper part of the car to overtake the lower part resulting in a rollover. This isnt the case here however as we speak about asphalt. There are several factors that affect the outcome of a possible rollover situation: Center of mass. The higher it is, the easier it is to make that mass assist a beginning rollover by pulling downwards. On the other hand, having a low center of mass - for example due a a pretty heavy battery pack - can greatly reduce the risk of a rollover as the mass wanting to force the vehicle into a rollover isnt much higher than the tyres: General weight distribution of the vehicle. The more heavy it is on the side of the loaded wheels the higher the risk of the sliding turning into a rollover. You should distribute a load as evenly as possible. Suspension quality and global stiffness: Softer offroad suspensions will make the vehicle lean in more while harder racing suspensions will make it lean in less. Tyre quality with it being a two edged sword: Having crappy tyres means they will generate less resistance to sliding, making it less likely to start a rollover. On the other hand, crappy tires will make you slide for longer meaning that your changes of sliding into something bad increase significantly. Not to mention that good tyres make it far less likely to slide out in the first place and will kill more velocity than poor ones while they have still ground contact. Worn or even damaged suspension components can greatly increase the probablity and severity of rollovers and other suspension related accidents.
by the way, I wasn't talking about using a rollover sled, i was talking about a roll caused by swerving. A roll caused by only the car
also tire temperatures and road temperatures affects how much the tires have grip on the road and affecting the rollover
I know I'm a bit late, but... Watching this snippet in the video, you can see the car bounce on the uneven ground, digging in the tires & throwing dirt in the air. Why didn't it flip In my opinion, BeamNG is already quite realistic as is, the only thing I would really like to see from ground simulation, is to have some "noise" in dirt/grass material, so the FFB won't feel like the car is driving on ice, as a more-or-less proper ground deformation will probably not come to the game anytime soon, if ever, on the current engine (Go to 6:23 if it doesn't put you there)
If you watch some of the Moose tests, you will notice that SUVs easily flip insdead of slipping. Even sedans would lift a wheel. So making cars easiler to flip is a step towards realism.
