About the Job

Requirements

  • Be in the final year of study (BAC+5) and seek a six-month internship.
  • Have knowledge of vibration analysis, structural dynamics, signal processing, FFT, modal analysis, instrumentation, and finite-element simulation.
  • Have proficiency in MATLAB, Python, and ANSYS or an equivalent tool.

Responsibilities

  • Inventory the existing configurations of test-bench structures.
  • Identify dynamic loads generated by engines and gearboxes.
  • Create a vibration map of the structures.
  • Determine natural frequencies and mode shapes.
  • Identify resonance risks with test excitation frequencies.
  • Propose improvements to increase the dynamic robustness of the installations.
  • Review structural dynamics, natural modes and frequencies, forced vibrations, resonance, experimental modal analysis, and FFT and frequency-analysis methods.
  • Define a measurement chain using tri-axis accelerometers, a data-acquisition unit, an instrumented impact hammer if available, a tachometer, and vibration-analysis software.
  • Develop a measurement plan for the structure.
  • Conduct impact tests to identify natural frequencies, determine damping, and construct frequency response functions.
  • Conduct operational measurements under different conditions, including engine speed, torque, gearbox type, and carried mass.
  • Analyze frequency spectra.
  • Build a simplified finite-element model using ANSYS, Nastran, or Abaqus.
  • Correlate the simulation with test results and update the model.
  • Study solutions including adding stiffeners, increasing stiffness, modifying ground connections, adding vibration isolators, and optimizing masses.
  • Evaluate potential gains.

Desired Qualifications

  • Knowledge of LMS TestLab, Dewesoft, or BK Connect.
