Kerb-strike

(OP)
Dear all,

   We would like to know the terminology "Kerb-strike".

 Can you help me in understanding the terminology "Kerb-strike"?

RE: Kerb-strike

Hitting the curb at the side of the road with your tire??

RE: Kerb-strike

A kerb (also spelled curb) is a raised edge of a road.  Here is a picture:



A curb strike is when a vehicle tire contacts the curb.  The angle, velocity, acceleration, stiffnesses, etc. determine the force transmitted into the vehicle.  This is a standard load case for vehicle dynamics.

RE: Kerb-strike

Yes, some dialects of English spell it "Kerb".  Corypad's picture tells the story.

RE: Kerb-strike

Important parameters are the forward and lateral speed of the car, the load condition of the car, and the strike angle, and the geometry of the kerb.

Your OEM will have their own tests and possibly equivalent pendulum rig tests, and I believe at least some legislatures have similar tests.

Failure criterion tend to be pretty subjective.

There's basically two types - high speed durability type events, where the car is intended to be entirely undamaged after many such impacts, and the maximum load case type events where significant damage and losss of function is acceptable from as few as three repetitions.

Thanks to Everyone...

I am quite clear with kerb(Curb)-strike.If I have further queries in this regard, I will get back to this forum...

  I was under the impression that Cory is an expert in Bolted connection and Greg in NVH. They know more than that and have multi-skills as it is required in mechanical engineering..Thanks again for your time...

RE: Kerb-strike

That's my /old/ job. Now I do computer based modelling of things like ride and handling... and estimating loads for suspension design.

RE: Kerb-strike

You can click on any member's name to learn more about them.  You can see from my description that I work for an automobile manufacturer, which exposes me to forces/stresses for components.  I just completed a project where curb strike fractured a control arm and stabilizer bar.  Bolted joints is just one area of specialization for me.
