The side frame primarily provides structural integrity to the bogie assembly, distributing loads between the vehicle body and wheelsets while maintaining proper wheel alignment and supporting suspension components.
Side frames undergo non-destructive testing including magnetic particle inspection for surface cracks, ultrasonic testing for internal flaws, dimensional verification of critical interfaces, and visual inspection for corrosion or damage.
Minor repairs following approved welding procedures are possible for certain defects, but significant cracks, deformation, or wear beyond specified limits typically require replacement to maintain structural integrity and safety.
