Free and Forced Vibration Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-DOMLE-10772
The experimental unit clearly demonstrates the fundamentals needed to deal with free and forced vibrations.
The central element of the experimental unit is a sturdy aluminum profile frame to which the different experimental setups are attached.
The differences between the two main types of excitation for forced vibrations can be shown on a simple vibration model.
A bar-type oscillator is used as the vibration system.
This offers easy and flexible configuration.
The spring, damper and vibration exciter can be mounted in any position.
An imbalance exciter and a displacement exciter are available for spring base-point excitation.
The excitation frequency is set and displayed on a control unit.
An oil hydraulic damper allows damped vibrations with adjustable damping level.
A mechanical drum recorder offers the option of recording the vibrations.
The measured values can be displayed and analyzed on a PC using the optional unit for data acquisition.
