⚙️ Ansys Tutorial: Random Vibrations Analysis | Stress, Displacement & Fatigue (Sigma Criteria)

Ansys Tutorial: Random Vibrations Analysis | Stress, Displacement & Fatigue (Sigma Criteria) In this tutorial, we’ll perform a Random Vibration Analysis of a four-deck rack using ANSYS Mechanical. You’ll learn how to set up *modal and random vibration systems*, apply a *PSD base excitation*, and evaluate results in terms of stress, displacement, and fatigue life using the *1σ, 2σ, and 3σ criteria*. We’ll cover every step — from geometry creation in SpaceClaim and shared topology setup, to modal analysis, PSD input definition, and fatigue evaluation based on Steinberg theory. 📌 What You’ll Learn: ✅Geometry and mesh setup in ANSYS SpaceClaim ✅Coupling modal analysis with random vibration ✅Applying PSD acceleration as base excitation ✅Evaluating deformation and stress using sigma criteria 📺 Subscribe for more tutorials on ANSYS and COMSOL Multiphysics simulations. 🌐 Explore More: 🔗 https://arminhashemi.org/ 🛠️ Need Help with a Project? 📩 https://arminhashemi.org/order-project/ 📸 Follow Me on Instagram:   / caewitharminhashemi   💼 Connect on LinkedIn:   / cae-with-armin   💡 Keywords: #Randomvibrationanalysis, #ANSYStutorial, #modalanalysis, #PSDacceleration, #fatiguelife, #sigmacriteria, #mechanicalvibration 0:00 4:42 Introduction 4:43 11:42 Geometry 11:43 14:02 Modal analysis 14:03 15:36 Results: Mode Shapes 15:37 17:02 Random Analysis 17:03 19:00 Boundary Conditions 19:01 19:99 Displacement & Stress 20:00 22:24 PSD Response 22:25 24:38 Fatigue Analysis
