The present invention relates to an impact excitation measurement system comprising a testing chamber, an impactor, a sensor system and a support system, wherein the impactor is configured to provide an impact to a test piece supported by the support system at said predetermined height, wherein the sensor system is configured to obtain a vibrational response of the test piece to an impact provided to the test piece by the impactor, wherein the support system is configured to support a solid test piece at a predetermined height within the testing chamber, wherein the support system comprises a set of support bars which comprise a thermal expansion coefficient which is essentially equal to the thermal expansion coefficient of the impactor, the set of support bars comprising at least three support bars each having a support end, which three support ends are positioned non- collinearly. |
