Universal Vibration Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-FMAHLE-7331
Jlab Export is a leading Universal Vibration Apparatus Manufacturer,and suppliers in India
Universal Vibration Apparatus (code EL-FMAHLE-7331) is a single teaching unit for the theory of vibrations, built around a universal frame on which pendulum, spring-mass, beam and torsional rotor experiments are quickly assembled one after another. The spares for every set-up are stored within the self-contained unit. JLab makes this universal vibration frame and its attachments in Ambala, India.

Experiments on One Frame
- Free vibration: undamped spring-mass system, longitudinal vibration of a helical coiled spring, and undamped torsional vibration of single and double rotor systems.
- Damped vibration: damped torsional vibration of the single rotor system, with the damping coefficient found from the results.
- Forced vibration: a simply supported beam at different damping, and forced damped vibration of the spring-mass system.
- Pendulums: the simple pendulum relation, the compound pendulum with its radius of gyration, and the radius of gyration of a bifilar suspension.
- Dunkerley’s rule, verified on the frame.
Free, Damped and Forced Vibration
Displaced and released, an undamped system oscillates at its natural frequency; for a spring and mass this is f = (1/2π)√(k/m). Adding damping makes each swing smaller than the one before, and the rate of that decay gives the damping coefficient. Under a periodic force the amplitude grows sharply as the forcing frequency nears the natural frequency, and the damping present controls how high that peak rises. Dunkerley’s rule estimates the fundamental natural frequency of a beam carrying several loads from 1/f² ≈ 1/f₁² + 1/f₂² + …, using the frequency each load would give on its own.
Vibration, Balancing and Gyroscope Rigs
- Vibration Lab — longitudinal and torsional vibration machine with control panels and speed indicators.
- Static and Dynamic Balancing Apparatus — shows the effect of unbalance in a rotating mass system.
- Motorised Gyroscope — variable speed rotor for gyroscopic couple measurements.
Machine-dynamics apparatus is grouped in Fluid Mechanics and Hydraulics Lab Equipment, part of Engineering Lab Equipment.
