Thanks again for the replies and clarifications. We can't have a ramp of any significance here, other than slight slope to shed storm runoff. The barrier will be about 1/3 of the wheel height, so as you suggested some energy will go into lifting the rear of truck. I think we're sorted...
Thanks so much for the great replies everyone. To respond directly:
Thanks mate. Yes - I agree about trying several approaches and enveloping results. Quick question - I'd like to be able to justify the assumptions you've made of 3km/h and 150mm deflection - are those figures from some...
Looking at impact loading on a barrier where mining trucks reverse up and dump their load over the edge into hoppers. Big loads, big wheels, but the speeds are low because they're slowing down to a stop - they know the edge is there. Not like an accidental veering off a road on a highway...
