Hi all, I’m attempting to measure dynamic loads on the pins and bushes at the indicated location on an excavator marked in blue. I’m thinking of installing a pressure transducer in-between the hydraulic hoses at the location marked in green. The data will be transmitted to the cloud. With...

Also, I hear what you're all saying about the pin being too short to consider bending, however that brings me further away from my goal of matching the FEA to the manual calcs. I would be properly convinced if i could see a reliable reference that says bending theory can only be applied to L/d...

Hi Nereth1, You're right. Shear stress will increase faster with a decreasing cross sectional area. Thanks for that. For the record, my calculated Von Mises stress is 369 MPa. This has been taken by assuming a point where both bending and transverse shear stress are at a maximum. The mentioned...

Hi JGard1985 Thanks for the helpful response. Although the issue still remains, I've taken your suggestions on board. The max stress reduced slightly after refining the mesh and achieved convergence to approx. +-5%. Although i agree the pin is short to consider it in a bending type model...

I am attempting to replace a 38kg solid pin with a hollow 16kg pin - ambitious, I know, but that’s what we’re here for. The pin is in double shear and has an estimated load of 140T, or 1,373.4kN. FEA “FEA Boundary Conditions.JPG” shows the layout of my FEA Analysis in SolidWorks Simulation...
