Free and Forced Vibration Apparatus
Description & Specification
Technical Specifications
The central element of the experimental unit is a sturdy aluminum profile frame to which the different experimental setups are attached. 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.
