Mode Shape Identification using a Displacement Sensor

Supervisor: Topaloğlu

Reference:  MODES1 (Acronym)

Student: Hayrettin Mert Yağız

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 low-cost device that identifies the mode shape of a beam will be constructed. The displacement sensor available in our department will move linearly over the beam surface with constant velocity, while the beam is being vibrated via a shaker. The motion of the sensor can be realized using a motorized lead screw or a similar mechanism. The identified 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 of the moving base for the displacement sensor.
  • Sine-sweep experiments with the shaker.
  • Postprocessing and evaluation of results. Comparison with theory

Required Qualifications and Skills:

  • Should have taken ME 445 & ME 403 courses.
  • Eager to design with electric motors and mechanisms
  • Eager to do experimental study
