Product Overview
The trainer covers a wide range of topics in mechanical vibration technology. It is mounted on a sturdy, low-vibration frame. Quick fastening elements for the formed grooves allow quick and accurate experimental set-up.
The apparatus consists of different sections which are concerned with vibrations study: different type of pendulums study, spring mass vibrations, rigid beam vibration free and forced as well as damped and un-damped, flexible beam vibrations, and rigid beam vibration free and forced with unbalance excitation.
The apparatus is installed with different pendulums, including 6 pendulums of different sizes and materials: steel ball small diameter, steel ball large diameter, wood ball large diameter, compound pendulum, compound wood pendulum, and bifilar pendulum. In the spring mass vibration section of this Universal Vibration Apparatus, users can study Hooke’s law and free hanged spring vibrations, as well as change different masses to study the behavior of the spring mass system.
In the beam vibrations, forced vibration is generated with an electrical motor-driven imbalance exciter. There are two types of exciter in this apparatus: one is a linear exciter with servo motor and driver, and the other is a DC rotary exciter. The exciter frequency can be set precisely on a control unit with digital display. An adjustable oil damper is used as a vibration absorber. A mechanical drum and a polar diagram recorder record the vibration. All parts of the apparatus are stored in a storage tray supplied with the equipment.
The optional sensor enables electrical measurement of the amplitudes of various oscillators. Alternatively, measured values can be evaluated with the software for data acquisition if the Data Acquisition Based System is selected (optional).
