B.E. (Automobile Engineering) Mechanical Vibrations Lab Syllabus - Mumbai University 2026
The University has moved this degree onto NEP 2020 one year at a time. The first and second years are NEP 2020 syllabi; the third and fourth years are still examined on the REV-2019 'C' Scheme, which is what the University sets for them this year.

Syllabus for Mechanical Vibrations Lab
Objectives
- 1 Study some single undamped degree of freedom systems theoretically and experimentally, and validate the time period of small vibrations/oscillations.
- 2 Obtain displacement vs. time graphs experimentally, and plot the same through response equations by the use of graphing and programming software viz., MS Excel etc.
- 3 Plot dimensionless steady-state amplitude vs. frequency ratio curves for various values of damping ratio for the case of forced vibrations, by the use of some programming software.
- 4 Balance a rotating system statically and dynamically.
- 5 Perform virtual experiments using Sakshat Virtual Laboratory.
Outcomes: Learner will be able to…
- 1 Derive the differential equation of motion, frequency & time-period, for the given single degree of freedom vibration system, for small oscillations.
- 2 Perform experiments on physical vibration systems and compare the theoretical and experimental results, for validation and verification.
- 3 Program using scientific mathematical software or using basic programming software, to obtain the necessary plots in time and frequency domains, and interpret the results thus obtained.

Reproduced from the University of Mumbai syllabus for B.E. (Automobile Engineering) under REV-2019 'C' Scheme, in force from the academic year 2021-22. Wording is as printed in that syllabus. The University sets no module list for this course; what she publishes is the objectives, outcomes and assessment guidelines reproduced above.
