damage analysis: cast iron properties

damage analysis: cast iron properties

(OP)
Hi guys

I have instrumented a tractor with strain gauges for measuring the loads of whole vehicle. The vehicle driveline is made up of cast iron. Whereas I have to analyse the structural damage of vehicle driveline to find the worst condition, do you know the cast iron sn curve slope? In  literature I have found different values, but I haven't understood what is the right value I have to use to perform this analysis. Thank you

RE: damage analysis: cast iron properties

FYI - I used to work for CaseIH. From what the tractor test engineers told me some of the worst loads for tractor structures in general come from using front-end loaders and snagging "immovable" items with a 3pt mounted ripper. I imagine that some of the front 3pt mounted tillage tools used in Europe would also case some large loads.

What does the manufacturer say they make the components from?

I'd drill a small shallow test hole in a few of the components.  If chips are dust, then I'd say there is essentially no ductility. If real chips, even short ones are formed, then the material has some ductility, and values for one of the ductile or SG irons might be close.

Did you happen to work on the hitch pump hydraulics of a 1586?

I discovered a problem with them.
