For the purpose of prediction, e.g. for designing decoupling measures to reduce sound and vibration, it is necessary to know the dynamic parameters of elastic elements in the relevant frequency range. For this, Müller-BBM has a test stand in Planegg to determine the dynamic stiffness of elastic elements. The test stand was designed for investigating spring elements which are used for railway superstructure, the construction of special ships and vehicle technology.
Characteristics of the test stand
| Maximum dimensions of sample | Width | 600 mm |
| | Depth | 600 mm |
| | Height | 900 mm |
| Maximum vertical static preload | 70 kN |
| Maximum dynamic force amplitude | 1700 N |
