Yup, don't need any IEDs, just put a kitten in the road in front of it.

Oh leaf springs, where art thou?

then don't forking do that! what the hell man. breaking your toys on purpose?

They are under all four corners of my rig.

Bit of an understatement.

That appears to be a prototype of the Force Protection Cougar, which actually has a pretty impressive service record when encountering IEDs. In 2004 there were 300 IED attacks on Cougars without any fatalities, which led the Pentagon to step up their orders. This one:

Was not only hit, it managed to drive back to base on three tires and that rim.

This one didn't make it back to base, but the crew survived with injuries so minor they were at work the next day:

All of this might make it sound like I'm shilling for FPV, but I'm not. I'm just saying that vehicle was designed with one very specific purpose in mind - keeping people alive after an IED attack - and it's apparently pretty good at it.

I wouldn't be surprised if the bolts holding the rear springs were not tightened properly, and finally snapped.
 
2012-09-22 09:13:35 PM  
Anti-Lock brakes would help, but obviously a design change is in order here.
 
2012-09-22 09:30:26 PM  
I think I see the problem.

This is why you have a highly trained R&D department. They get paid to brake things as they test the operational limits of the tested item.

I think those WERE anti-lock brakes.

It seems unlikely that you could do something like that without a weak bolt in the suspension or something like that. I mean, the Mythbusters tried to actually accomplish that exact feat by critically weakening parts of the car and barely managed it.

It was a prototype. You can see the track wheel on the far side of the vehicle that was measuring distance and acceleration. It looks like a small training wheel running alongside the vehicle during both runs.
 
2012-09-22 11:16:04 PM  
To be fair, the brakes did stop it.

You are correct

Seriously, fark driving those things in full gear.

That's some fine fused brake cylinders there, Lou.

yup axle broke loose. better get the duct tape.

Meh. A couple of bungee cords, and good as new.

never would have happened if they used self-sealing stem bolts.

EnviroDude: This is why you have a highly trained R&D department. They get paid to brake things as they test the operational limits of the tested item.


That's what I was thinking. Shiat is going to break, no matter how well engineered. And given that our military is the world's largest collection of experts at breaking shiat, it's good to know ahead of time exactly how much abuse the equipment can take.

Yeah, but consider the weight difference...a 1 ton automobile as opposed to a 14.5ton+ MRAP. That's a hell of a lot more force on those connections.

Holy crap! And why do we keep pouring more billions into Military spending? To buy this POS? I bet they are really expensive too.
 
2012-09-23 04:38:34 AM  
Ooouuuuch! But hey, better that they find the weaknesses in testing than in combat. Wish they'd had these back in the day when I was in Iraq (2003). Hell, we were lucky to get decent body armor and sandbags to line the duce-and-a-halfs back then.

/yeah, get off my lawn :P

rev. dave: Holy crap! And why do we keep pouring more billions into Military spending? To buy this POS? I bet they are really expensive too.


And you think this crap doesn't happen in testing with commercial vehicles? There is a reason it's called *DEVELOPMENT*, not "magically shiat out a finished product on the first pass."

And every effort to eliminate development and replace it with navel gazing and computer design generally leads to a spectacular failure on release and having to do all of the development you were trying to negate by being overly analytical.

I was thinking of the ones that the back didn't fall off.
 
2012-09-23 08:47:21 AM  
Nobody is curious why only the back wheels locked up? Or why the front didn't dive under heavy breaking? Looks to me like they're throwing it in park, or engaging the parking brake.
 
2012-09-23 08:55:25 AM  
See the importance of proper spelling, kiddies? The driver was supposed to hit the brakes, but he hit the breaks

Spelling nazis only want what's best for you..

Misha80: Nobody is curious why only the back wheels locked up? Or why the front didn't dive under heavy breaking? Looks to me like they're throwing it in park, or engaging the parking brake.


The front didn't dive because suspension carrying ten tons of armor doesn't have a lot of travel. And the back wheels locked up because there is far more weight on the front wheels. In any car or truck at speed the front wheels do 80% of the braking. The rear wheels have far less weight on them and will lock far more easily. It's the same on a bike. Using the front brake will slow you down. Using the back brake will lock the wheel.

GAT_00: It seems unlikely that you could do something like that without a weak bolt in the suspension or something like that.


The reason for tests like this is to find exactly that.
Wrecking something intentionally is a good way to identify its weaknesses.
 
2012-09-23 09:20:17 AM  
To be fair, I didn't see a lot of background on that test. Were these vehicles the type out there now or was this engineering test footage? When I first saw it was on an airstrip I thought it was Top gear related.

Also, if those were the same vehicles that Lsherm posted I would say they did a fine job on the IED portion of the test.

Speaking of Top Gear and military type vehicles:

Probably should have quit after the first test...

No, you keep testing until shiat like this doesn't happen anymore

Good ol' 550 cord, between that and 100mph tape you can fix anything.

If you want the fix to last, use more zip ties.
