THE NEW IMPACT FORCE MACHINE AT PTB

Michael Kobusch, Thomas Bruns

Abstract

The prototype of a new facility for impulse force calibrations is presented in this paper. Furthermore, first experiences and measurements are described. Impulse forces are generated by a collinear impact of two cubeshaped bodies guided by linear air bearings. Traceability of force is realised by the determination of mass and acceleration, where the latter is derived from the velocity signal of a Laser-Doppler interferometer (LDI).
