Planetary gears are used when an application requires high reduction ratio in a small space, which is a common scenario in many automotive applications, especially in heavy machinery applications (tractors, trucks, etc). In this application, two planetary gears were coupled to provide a 20:1 reduction ratio in a 80 kW/109 hp motor at 3000 rpm. The objective of this simulation is to verify the structural integrity of the system enclosure. This verification will evaluate the von Mises Stress and compare it with the Tensile Yield Strength for Aluminum 5083-H116, which is a common verification for yielding in ductile materials.

On this project the structural integrity of a Steel Stair (AISI 1020) was verified. The case studied was a steady 10kN load ( around 1Ton) applied in the imprinted face shown on the comments. The verification used the von Mises Stress to predict the bridge behavior due to the load.
