Rail Fatigue Rig

Rail Fatigue Rig is an automated system to measure and study the structural strength of bogie frames, its components for rolling stock, railway tracks and sleepers by creating progressive & localized structural damage from different directions at various cycles. These tests help to engineer and design better Railway Infrastructure.

Following factors affect the Fatigue Life;

• Cyclic Stress State
• Geometry
• Surface Quality
• Material Type                                                                
• Residual Stresses
• Size & Distribution of Internal Defects
• Magnitude & Direction of Loading
• Grain Size
• Environment
• Temperature

This system was developed for RDSO along with IIT-Kanpur
