The Structural Analysis Engineer will work closely with design and validation teams to evaluate structural integrity, predict component performance and service life, and provide actionable recommendations that influence product design.

Duties & Responsibilities:

• Perform structural analysis and simulation to evaluate structural integrity, response, performance, durability, and service life of cooling and aftertreatment components and systems.

• Perform FEA involving:

  • Static structural analysis
  • Vibration and modal/dynamic analysis
  • Transient dynamic analysis
  • Boundary nonlinearities
  • Material nonlinearities
  • Fracture analysis
  • Fatigue and fatigue-life prediction
  • Bolted-joint analysis
  • Welded-structure analysis

• Analyze complex structural behavior associated with engine and machine vibration and forced response.

• Interpret simulation results and provide design and development teams with clear technical conclusions and actionable recommendations.

• Support New Product Introduction (NPI) and Current Product Improvement (CPI) activities.

• Collaborate closely with Cooling and Aftertreatment Design Engineering teams.

• Partner with test and validation teams to correlate analytical predictions with physical test results.

• Investigate structural failures and performance concerns and recommend appropriate design improvements.

• Continuously improve structural analysis methods, processes, modeling techniques, and simulation accuracy.

• Prepare and communicate technical analysis results, conclusions, and recommendations to engineering stakeholders.

Education & Experience

• Bachelor’s degree in Mechanical Engineering or a related engineering discipline with approximately 5–7 years of relevant experience, OR
• Master’s degree in Mechanical Engineering or a related engineering discipline with approximately 2–4 years of relevant experience, OR
• PhD in Mechanical Engineering or a related engineering discipline with approximately 1–2 years of relevant experience.
• Industrial experience performing structural analysis/FEA, preferably involving static and/or dynamic structural analysis.

Required Technical Skills

• Strong understanding of structural mechanics and dynamics.

• Strong understanding of material properties and material behavior.

• Knowledge of fatigue and durability fundamentals.

• Hands-on structural simulation experience involving several of the following:

  • Static analysis
  • Modal/vibration analysis
  • Transient dynamics
  • Nonlinear analysis
  • Material nonlinearities
  • Contact/boundary nonlinearities
  • Fracture
  • Fatigue-life analysis
  • Bolted joints
  • Welded structures

• Strong hands-on experience with ABAQUS.

• Strong hands-on experience with HyperMesh.

• Ability to develop FE models, define appropriate loads and boundary conditions, evaluate results, and translate findings into engineering recommendations.

• Ability to understand complex structural behavior and troubleshoot simulation/modeling issues.

Preferred Technical Skills

• Experience with machine dynamic simulation.
• Experience analyzing engine, heavy-equipment, automotive, off-highway, or other mechanically dynamic systems.
• Experience with nonmetallic structural simulation.
• Experience developing or implementing user-defined material behavior/models.
• Experience with component interaction and contact modeling.
• Experience with machine and structural design and validation.
• Experience correlating FEA results with physical testing.
