Shaft Dimensioning FEM vs. Analytical

Shaft Dimensioning FEM vs. Analytical

Shaft Dimensioning FEM vs. Analytical

(OP)
Hi guys! I am trying to perform a simulation with two bearings in a FE simulation and want to calculate the shaft analytically as well. Do you have any resources on how to calculate this case? I have the FE Model already and want to apply torque at the end of it. Any help is much appreciated! Would it also be "easily" possible to do this calculation if the shaft expands (thermomechanics)?

Thanks!

RE: Shaft Dimensioning FEM vs. Analytical

Approach to shaft analysis is similar both in FEA and hand calculations. Loads (bending and torsion) are applied in places where gears are mounted while supports are placed where bearings are. In case of analytical strength evaluation this can be simplified to beam subjected to combined loading. All books about mechanics of materials have a chapter on that. Shafts are the most popular examples there. For FEA similar method can be used. Place boundary conditions (supports) where bearings should be and apply loads in place of gears. Thermal stresses can be evaluated easily using FEA. Unfortunately it's hard to find any valuable resources about FEA modeling of regular shafts.

Thanks a lot for your answer!

Do you have any internet resource that I could use as an example? I am basically trying to "reproduce" the reaction forces on the bearings that will then be used to dimension those using a bearing catalogue.

White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
White Paper - Model Based Engineering for Wire Harness Manufacturing
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
