Vibration trainer (TM 150)

Vibration trainer (TM 150)

detailed, wide-ranging series of experiments on the mechanical vibration theory

CodeTM150

Description:

  • 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 TM 150vibration 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 tuneable 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 TM 150.20unit for data acquisition.
