Support bed for impact measurements

An impact excitation measurement system comprising a temperature-controlled testing chamber, an impactor, a sensor system and a support system,

• wherein the impactor is configured to, at any testing temperature within a testing temperature range of between 0° C. and 1600° C., provide an impact from below to a test piece supported by the support system,
• wherein the sensor system is configured to obtain a vibrational response of the test piece to the impact provided to the test piece by the impactor,
• wherein the support system comprises a bedding for supporting a solid test piece within the testing chamber, said bedding comprising an elasticity which is substantially larger than the elasticity of the test piece, said bedding further comprising a through for allowing the impactor to provide an impact to the test piece from below,
• wherein the impactor is configured to provide the impact to the test piece at an impact height which impact height is at least partially dependent upon the testing temperature,
• wherein the bedding is configured to support the test piece at a support height which differs from the impact height for at most 0.5 mm at any testing temperature within said testing temperature range.
