Plate Bumpers after impact with pics?

I'd like to see a modern piston steel bumper in tests to see how close it is. Not the original old stuff, things improve over time.
And what do you mean, guidlines? I do not follow

 

What is this "ugly lower lip" you speak of? I don't think my taco looks ugly lol.

I mean, if they don't want cars to kill people if they strike them then they had better just get rid of cars or make better driving skills a requirement... I mean seriously, it's an unfortunate cost to automobiles existing. But getting hit by a car is going to almost always kill you (above a certain speed) unless they make the whole thing out of jello or something. lol

 

Still, you could use a steel gas piston bumper with this in mind. I don't see why it couldn't be done. As I said it is just another excuse to sell more cars lol

 

No, there is no crumple zone. Crumple zone is a unibody vehicle concept where energy is dispersed through the vehicle to protect the passenger compartment. That doesn't apply to full frame vehicles. Cans, "shocks", and whatever manufacturers put behind their bumpers since the Model T until today haven't done anything above 5 mph. Think about it. A two ton vehicle moving ten mph is a shit ton of force for any device to disperse. 1.3372e+4 ft lbs actually. That will smash it then transfer the energy to the frame or not smash it and immediately transfer the energy to the frame.

 

No.

 

This is the wrongest statement I have ever read on this forum... SMDH.... maybe it's time for you to watch some IIHS crash tests

 

I felt the same way. The issue is acceleration. The taco frame, like many others has weak points that bend allowing it to accordion and reduce high deceleration rates. Totaling a vehicle is far cheaper than health costs. Simple economics.

 

I'm disputing your seeming assertion that there is a magical crumple zone associated with any bumper system that can protect the vehicle from damage at anything other than a very, very, low speed impact. That's the topic, bumpers.

If you want to talk about high speed IIHS or NHTSA crash test ratings for occupant safety we can do that too. Maybe another thread though. Make up your mind.

 

We were talking about bumpers.

IIRC you were the one that tossed out a number based upon the entire weight of the vehicle, which brings the frame and all into the mix.

Pickup trucks manufactured in the last ten years have deformations in the frame to allow it to crumple.

I wouldn't be too surprised if the frame bends and the bumpers do not, especially in a multi vehicle chain reaction.

You can't jump back and forth like this without creating confusion.

Yes, it's a 5k plus lb vehicle. If I drive it into a solid block of stone at five miles per hour, I expect something to bend. If I drive it into sheet metal thinner than the bumper, I expect the bumper to win.

This is from the ARB site:

AIR BAG COMPATIBILITY
With an air bag equipped 4x4 it is essential that the vehicle's crush rate and air bag triggering is not altered when a bull bar is installed. To ensure compatibility, ARB assesses each vehicle's frontal crush characteristics and replicates the crush rate into the design of each air bag compatible bull bar and its mounting system. This method enables engineers to achieve maximum possible vehicle and passenger protection without affecting the crash pulse. ARB has invested heavily in vehicle crash barrier tests to validate the performance and compliance of its air bag compatible bull bars, and as a consequence, our bars offer a far greater level of protection than most standard brush guards and grille guards.

Please note that a few of the bumpers for older model vehicles are not air-bag compatible, refer to the Vehicle Application Guide for confirmation.

 

I’m unsure who I’m rooting for here. Can we just get back to pics of plate bumpers after impact?

 

I agree lmao, been awhile since we had any carnage

 

Have you sat down and created prototypes and tested things? You cannot say no unless you or someone else actually takes the time to test these things, and I'm not talking about tests done 30+ years ago.
So, basically get the steel plate bumper, weld reinforce your frame up a bit, and then keep it under 55 mph and don't goof around while driving.

 

You know, perhaps the fact that most other small vehicles have weaker/more plasticy crumpling fronts makes it easier for the plate bumper and frame to survive? As in, the tacoma's with steel bumpers are using the other car as the "crumple zone". lol. You can see in the photos that the other vehicles are basically destroyed while the taco's look unharmed, so it makes me lean towards this idea. The smaller cars are absorbing the impact, or at least most of it.

Hitting another strong full framed vehicle like a truck would probably cause actual damage. I would assume, so I guess it depends on which vehicle can "use the other as a crumple zone". So I guess if you get a plate bumper and you have to hit someone, hit the civic or the geo.

 

Intresting hypothesis, next step is to test it haha

 

Lol yes

 

Yeah see? So it looks like the plate bumper works as long as you hit a whimpy non-steel-plate bumper car.

 

Or a couple of cows

 

As with most things in life it is probably bullshit.

However I would trust it more in saving me from injury than one from a small shop. Some of them may be ok hold a winch, but wouldn't work too well hitting a deer.

Ugly as all get out, but rather have this:




than this: Do think the CBI is better looking, but the ARB simply has more material to absorb/deflect an impact. Don't think there are any crush cans on the CBI either.

 

Main reason I run one. When I lived in AZ I liked to run up to Colorado for vacation...always tend to hit the mountain roads in the wee hours of the morning...the amount of wildlife alongside of the road is staggering. One of the first years up there witnessing that...came home and bought my ARB. Though pretty much screwed with moose or elk. Need a much bigger truck for that!

Bought my used off CL, that was in a small fender bender...the guys insurance bought him a new one, so he sold the old one...it had a small dent, and one of the crush cans had a small crack...so put new crush cans on it as a precautionary measure.

It has been on there for 15 years...and haven't had to use it yet (knock on wood)...gets used more as a coffee table than anything when I am changing the oil and rotating the tires...like today, pulling my snow tires off here in a bit.
