ResumoA method for evaluating the dynamic response of force transducers against an oscillation force is proposed. In the method, a force transducer is connected to a mass by a spring, which generates the oscillating force after the mass is manually hit using a hammer. A pneumatic linear bearing is used to realize linear motion with sufficiently small friction acting on the mass, which is the moving part of the bearing. The inertial force acting on the mass is determined highly accurately by measuring the velocity of the mass using an optical interferometer.
