Lumped Mass Vibration/Controls Experiment

The vibrational and control system study of a multi-degree of freedom lumped mass apparatus is examined with this apparatus. This experiment requires LabVIEW software and a National Instruments DAQ system to record results.

Experiment Time: 1 Hour

This experiment and apparatus is designed to investigate:
  • Controls Experiments:
    1. The calculation of the system transfer function for a physical system in the 's' domain.
    2. The calculation of the system transfer function for a physical system in the time domain.
    3. Experimental verification of the transfer functions upon testing the system.
    4. Developing a control routine in LabVIEW to control the response of one of the blocks to a pre-described position or position function.
  • Vibrations Experiments:
    1. mass-spring unforced 1 DOF system response
    2. mass-spring-damper unforced 1 DOF system response
    3. mass-spring SHM forced 1 DOF system response
    4. mass-spring-damper SHM forced 1 DOF system response
    5. mass-spring 1 DOF step input system response
    6. mass-spring-damper 1 DOF step input system response
    7. mass-spring 2 DOF SHM forced system response w/ zero initial conditions
    8. mass-spring-single damper 2 DOF SHM forced system response w/ zero initial conditions
    9. mass-spring 3 DOF SHM forced system response w/ zero initial conditions
    10. mass-spring-single damper 3 DOF SHM forced system response w/ zero initial conditions
Time Requirements (for a recommended group size of 2 to 3 people):
  • Setup Time: 15 to 25 minutes
  • Experiment Time: approx. 90 minutes
