Optimization of availability and maintenance costs in case of mechanical problems on rolling stock

Project tasks:

• Failure-cause analyses
• FE analyses as a basis for strength verifications and service life estimations
• Crack propagation calculations
• Multi-body simulations as a basis for system understanding (dynamics, kinematics, loads)
• Clearance and gauge analyses
• Design of repair solutions
• Independent expert assessment
