Free and Forced Vibration Apparatus
Free and Forced Vibration Apparatus
SKU: HI MDM-006

The "HANSA" experimental unit clearly demonstrates the fundamentals needed to deal with free and forced vibrations. The differences between the two main types of excitation for forced vibrations can be shown on a simple vibration model.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.Free and Forced Vibration ApparatusFEATURES:Demonstration of basic fundamentals of mechanical vibration theoryFree vibrationsDamped vibrationsInertia force and displacement excitationForced vibrationsResonanceAmplitude response and phase response SPECIFICATION:Fundamentals of mechanical vibration theory; free, damped and forcedBar-type oscillator: LxWxH: 700x25x12mm, 1,6kgCoil springs0,75N/mm1,5N/mm3,0N/mmExciterFrequency: 0?50Hz, electronically controlledImbalance of the imbalance exciter: 0?1000mmgStroke of the displacement exciter: 20mmDamper constant: 5?15Ns/m, oil-filledMechanical drum recorderFeed: 20mm/sPaper width: 100mmRequired for operation230V, 50Hz, 1 phase230V, 60Hz, 1 phase; 120V, 60Hz, 1 phase DIMENSIONS AND WEIGHT:L x W x H (approx.): 1200 x 600 x 1400 mmWeight: 125kg
