Laser-welded collision bumper for a rail car constructed of sheet steel: Computer model of construction and finite-element analysis of stress under collision loading
  • development of design for collision bumper of a rail car using novel sheet steel construction
  • implementation of laser-welded tab-and-slot joints
  • development goals:
  • reduction of fabrication costs
  • minimization of component weight
  • guaranty of load capacity under crash conditions
