DEVELOPING IMPULSE GENERATOR BASED ON THE LAW OF CONSERVATION OF MOMENTUM, PART-1: IMPULSE RESPONSE MEASUREMENTS OF FORCE TRANSDUCERS
Y. Fujii
Abstract:
In this paper, present status of the developing impulse generator based on the law of conservation of momentum is reviewed. Impulse responses of two commercial force transducers are evaluated by means of this method. In the experiment, an object levitated with sufficiently small friction using a pneumatic linear bearing is collided with a force transducer. The inertial force acting on the object is measured as the product of the mass and the acceleration. Approximately 160 sets of collision experiments, whose impulses with the maximum value of approximately 20 to 230 N with the half value width of approximately 10 ms to 40 ms, have been conducted using two commercial force transducers and two dampers. The instantaneous value of inertial force is measured with the sampling period of approximately 0.15 ms. its standard uncertainty is approximately 0.9 N, which corresponds to approximately 0.4 % of the maximum applied impulse.
