I can't seem to find any COF number for rubber on aluminum or steel. All the tables I can find seem to ignore those two combinations.
Does anyone out there have any experience or a source that can help me answer this question? My application is a truck tire on a flooring plate in a factory and...
metman,
By positive slope relationship I meant that the higher the yield strength, the higher the hardness. In addition, there is a pretty strong correlation of this by the high R-squared value.
As for the selection of the 80ksi yield material, I can't seem to find a specific reason why that...
EdDanzer, could you please elaborate on the cast iron point you made? Why is this so? Because we do have experience with the current thickness and it hasn't been an issue. I am presuming that the plate is thick enough to avoid the denting and cracking problem you mention.
Based on what I...
Guys, I really do appreciate all the great ideas but NickE actually hit the nail on the head precisely with his analysis of the situation. The problem is price and availability or else I wouldn't be in this situation in the first place.
By the way, metengr, we have looked at some of the higher...
NickE, I was thinking along the same lines you suggested, looking at hardness, so I looked up various yield strength steels with published hardnesses and ran a quick-and-dirty regression analysis and found a positive slope with a 94% R-squared value. In a round-about way, I ended up answering...
EdDanzer, the application is the lower, front, bottom surface of a semi-trailer which gets bashed by tractors picking up the front of the trailer to engage to it's "kingpin". After picking it up the coupled vehicle goes down the road with a lot of sliding radially on every turn as well as the...
Thank you CWIC and metengr for your quick responses. I'm sorry but I guess I left out some details that were pertinent to my question.
The wear I'm talking about is of the "abrasion" and "sliding damage" nature. I am considering changing the material for my application from an 80 ksi yield...
Could someone offer me some advice on the "wear-ability" of steels of varying grades? (i.e. 80ksi vs. 50ksi vs. mild steel) Is there any correlation between yield strength and "wear-ability"? Thank you.
