Mass measurement using the fixed-point of a spring-mass system with a dynamic vibration absorber and an inertial-mass vibrator

A mass-spring system with a dynamic vibration absorber has a fixed point in its frequency response curves. A method of measuring mass using this property was proposed. It has an advantage that mass is estimated independently of the damping in the absorber. The developed system was characterized by u...
