EM-408 | Vibration Trainer

Mechanical vibrations are usually found as an unwanted side effect in many areas of engineering. Examples include vehicle vibrations on uneven roads or engine vibrations. Vibration theory is a particularly challenging area in the field of mechanics. The vibration trainer can be used to study many topics from the field of vibration theory through experimentation. The topics range from simple pendulum-swinging forced vibrations with resonance to vibration absorption. The central element of the vibration trainer is a sturdy profile frame, to which the different experimental setups are easily attached. The extensive accessories are housed in a mobile laboratory table with drawers. In addition to free vibrations, forced vibrations can also be represented by means of an electric motor imbalance exciter. The excitation frequency is set and displayed on a control unit. An oil damper allows the study of damped vibrations with adjustable damping ratios. Vibration absorbing is demonstrated with a tune able bending oscillator. A mechanical drum and a polar chart recorder make it possible to record vibrations. The measured values can be displayed and analysed on a PC using the optional unit for data acquisition.
