Mechanical Vibration Laboratory
Lab-in-charge:
Dr. Shitendu Some
Details of Laboratory:
Universal Vibration Apparatus (TM150 and TM155) are used for conducting various experiments such as single pendulum, compound pendulum, bifilar suspension for determination of M.I., spring mass system with damped vibrations and others. A universal frame is provided upon which quick and easy assembly of various experiments can be done. The students can easily assemble the experiments and study the theory of vibrations practically.
Laboratory Equipment
TM150

Course Outcome:
Upon completion of this laboratory course, students will be able to
- Perform experiments and manipulate key variables to investigate the mechanisms and mechanical vibrations’ principles.
- Investigate acquired experimental data of mechanical systems with derived quantities.
- To determine the natural frequency of vibration problems that contains single and multi-degree of freedom systems.
- To calculate the damping coefficient of single and multi-degree of freedom systems.
Safety and Security Rules to be Followed in Laboratory:
- Always wear shoes before entering in the lab.
- Do not touch anything without the permission of instructor/ lab assistant.
- Read carefully the lab manual before performing experiments.
- Do not tamper measuring instruments.
- Do not open the casing of the equipment.
- Switch off the power supply to the experimental setup on completion of the experiment.
- Maintain clean and orderly laboratories and work area
- Be aware of the various experiment controls (start button, stop button, speed control) for each experiments.
- Do not leave experiments running unattended.
- Any injuries should be reported immediately for proper care.
