in a piston pump the flow pulsation depends by the number of pistons. A single piston pump has a much more irregular flow than a 5...

I don't know why but in internet it's easy...
as I wrote some posts ago, Shigley and Juvinall in their books discuss about the Wohler curve construction.
You can easily refer to...
In the graph the terms means:
- FLESSIONE = BENDING
- TORSIONE = TORSION (this was easy to understand :p)
- SFORZO NORMALE = AXIAL LOAD
These graphs are for GJS 600 and they are the standard curves:
- Wohler standard specimen Ã˜7.5 mm
- 50% safe accuracy
- polished surfaces
Great!!!!!!!!!!!!!!!! It works
I'm not so dumb as I thought :p
I will try to post the image from my personal pc later.
In the meantime I want to correct an inaccuracy I wrote in my previuos post: the specimens used by Wohler during his tests were Ã˜7.5 mm and not...
The problem is that now I'm writing from the office pc and the company provider blocks some internet sites...among which photobucket :mad:
thanks for your help :D
As I understood, the only way for posting files is through a hosting site.

Hi Kaka and welcome to this great forum!
What you are looking for is rather difficult (or impossible:cool:) to find: the fatigue limit depends by...
Hello JoeS and welcome to the forum!
I quote bdeuell answer.
The problem is rather simple: if you know the mechanism geometry it is simple to...
Hello vysang and welcome to the forum,
if the shaft rotates it is subject to fatigue loads even if the load appears static...unless it is loaded...
I think the FEA simulation is not necessary. :)
It is suffice a white paper sheet, a pen and the levers theory
is always a pleasure to read your posts! :)
I agree with you about the freehand sketch.
I'm a bit younger than you: I attended...
I had quick sight to the photos.
Here there is the hydraulic cylinder
You can see two red cables, one for the flow...
Hi to all,
sorry for my temporary absence :rolleyes:
As Lochnagar has already replied, the hydraulic circuit moves a hydraulic cylinder that...
