Measuring Eigenfrequency

The Eigenfrequency of a system, capable of vibrating, is the frequency, with which the system vibrates, after having been stimulated once. If damping is disregarded, the Eigenfrequency is the same as the resonance frequency.

For measuring the Eigenfrequency, the storage of the object measured (damping!), the settings and parameters of the measuring system and possibly also the age and further parameters of the object being tested must be taken into consideration.


  • Excellent price to performance ratio
  • Suitable for different products with a minimum of retrofitting expenses
  • Ensures that customer and Federal Law regulations are observed
  • Modular expansion possible, thus ensuring future viability
  • Reliable Eigenfrequency values due to multiposition measurement and aging compensation
  • The particular: Q-factor measurement



The measurement and monitoring of Eigenfrequencies ensures that a component or subassembly, when installed in a system, does not stimulate other areas to vibrate impermissibly.

Testing Technique

RTE offers a high-performance system with short cycle times and an excellent price to performance ratio. The test system offers different expansion modules, such as compensation methods for unavoidable influencing factors during the production process (batch, age). The results are documented simply and quickly.

For example, requirements, which are to be met by components of braking systems, such as brake discs, are set down in EKB 2002, the serial testing regulation of the European Brake Knowledge Experts Group, which is used by all vehicle and vehicle component manufacturers.
