Mode Shape Identification Using a High Speed Camera

Reference:  MODES2 (Acronym)

Student: İlyas Berkay Tural

Identification and measurement of the mode shapes of a beam structure usually requires advanced devices such as Laser Doppler Vibrometers, or advanced image processing techniques. In this project, a high speed video camera will be used for identification and measurement of the first mode shape of a cantilever beam. The high speed camera will be mounted and the beam video will be recorded during its forced vibration. The forcing will be realized with the shaker available in the department. The video data will be postprocessed in order to obtain the mode shape of the beam. The mode shape will be compared with theory for a uniform rectangular cantilever beam.

Work Description:

  • Study on mathematical modeling of thin beams with base excitation
  • Design and construction an experimental setup with the shaker, beam and high speed camera
  • Sine-sweep experiments with the shaker.
  • Postprocessing and image processing
  • Evaluation of results. Comparison with theory

Required Qualifications and Skills:

  • Should have taken ME 445 & ME 403 courses.
  • Interest in image processing
  • Eager to do experimental study
