Planetary Pinion System Simulation
In this project, I conducted FEA analysis and acquired the max stress, pinionshaft slope and the endurance of the system. Base on the results, I modified the system so that the endurance of the pinion increased by 30% and the slope of the pinion shaft decreased by 10%
• The assembly was built in NX.
• The assembly was meshed in Hypermesh with simplified pinion .
• With loads and constraints applied, the model is imported to Abaqus and the simulation was conducted.
• Made comments on the design in terms of stress analysis, fatigue analysis and pinionshaft slope analysis, and then modified the system by changing material and design parameters
Skills: UG NX, Hypermesh, Abaqus, Femfat, Material Mechanics, GD&T, Gear Simplication
 |  Step1:NX ModelingA planetary pinion system is built in NX. To simplify the structure and analyse the pinions, the ring gear and the sun gear are omit in the second picture. |  Step2: Hypermesh ModelingAnalyzing loading and boundary conditions, then established CAE mesh work in HyperMesh.Export inp.file to Abaqus simulation. |
|---|---|---|
 |  |  Step 3: Abaqus AnalysisConduct the stress analysis and fatigue analysis; acquire the slope of the pinion shaft by analyzing the data.file. Modify the system so that the endurance of the pinion increases by 30% and the slope of the pinion shaft decreases by 10% |
