Materials Screen Exciter Beam Fatigue Assessment

Nebo Project Engineers (BlueScope Steel, Port Kembla, NSW, Australia)

Nebo Project Engineers required fatigue assessment and design modification of a materials screen exciter beam for BlueScope Steel (Port Kembla). Avesta Consulting performed dynamic structural analysis and fatigue assessment to verify strength and fatigue life of the exciter beam components in accordance with standards AS 3990 and AS 4100 considering cyclic loading data.

What we did:

  • Performed static structural and harmonic response FEA of proposed replacement exciter beam design.
  • Determined fatigue life of exciter beam components considering cyclic loading data.
  • Modified design of stiffeners to achieve design life requirements.

Outcome:

Avesta Consulting verified structural integrity of the proposed exciter beam and modified the stiffener design to achieve fatigue life requirements.
