vibrations generated via imbalance
- An indispensable part of machine design is the reduction of vibrations.
- For example, an elastic, vibration-isolating setup of the machine avoids disruptive vibrations being transferred to the surroundings.
- The TM 182unit can be used to study the issue of machine foundations and isolation from vibrations using a practical example.
- To do this, vibrations are deliberately produced on an elastically mounted machine.
- The transfer of these vibrations to the foundation is measured.
- It is then possible to test different adjustments using different springs and to study absorbing effects using vibration absorbers.
- The experimental setup consists of a machine, a foundation and a frame.
- A vibration generator serves as the machine, consisting of two independently driven imbalance sets.
- The imbalance sets are driven by servomotors so that any excitation forces and force directions can be generated.
- Alternatively, a piston compressor (TM 182.01) can be used to generate vibrations.
- The machine is mounted on a foundation by means of springs and dampers.
- The surroundings are represented by the foundation, on which the effectiveness of the vibration isolation is measured.
- The foundation is connected to the actual frame of the trainer via additional coil springs.
- This dual vibration isolation, together with the large weight of the foundation itself, guarantees a vibration-free operation in the laboratory even under unfavourable experimental conditions.
- A switch cabinet is attached to the frame, housing the control system, power supply and data acquisition.
- Acceleration sensors are used to measure deflection, velocity and acceleration of the vibrations at different points.
- Using these measured values, it is possible to calculate and display the operational vibration modes.
- A comprehensive software program is provided to control the operating conditions and to capture and analyse the data.
- The unit is connected to the PC via USB.
