Vibration Reduction on Machines and Plants

In order to influence the vibration behavior of machines and plants, there are various approaches. Which of the measures listed below is most suitable for your specific vibration problem and whether it is possible to implement it depends on many parameters – for example, the vibration level to be achieved or the installation space.

Mass balance
Balancing
Optimization of the drive or its control system

Optimizing the natural frequency position through design adaptations
Semi-active components
Adapting cycle times or speeds

Machine bearing
Machine foundations

Passive absorbers (e.g. TMD.Pipe)
Semi-active absorbers
Active absorbers (in wide range frequency variable, e.g. ADD.Sound)

Vibration reduction on existing machines and plants

For machines that are already in operation, the number of implementable vibration reduction measures is usually significantly lower. The task here is to find and implement the best possible solution in a short time and without costly trial-and-error procedures. The typical process is as follows:

1. Vibration measurement

Specification of the vibration problem and identification of the cause

2. Vibration reduction concept

Elaboration of one or more concepts for vibration reduction
Evaluation of the concepts (e.g. effectiveness estimation based on numerical simulations)
Selection of the concept to be implemented

3. Implementation

Selection of a suitable solution available on the market or design and construction of an individual hardware solution
Commissioning and documentation of effectiveness
