UNCERTAINTY CONTRIBUTIONS OF THE IMPACT FORCE MACHINE AT PTB

Michael Kobusch, Thomas Bruns
  • Abstract:
    This paper gives a comprehensive overview about the contributions to the measurement uncertainty of the 20 kN Impact Force Machine at PTB. Various influences resulting from interferometric velocity measurements, data analyses, mass determinations and parasitic forces are described and estimated by theoretical or experimental data if possible.
