SIMPLIFIED MODEL OF MASS MEASUREMENT SYSTEM WITH CONSIDERATION OF VARIATION OF FULCRUM POSITION

Y. Yamakawa, T. Yamazaki

Abstract

This paper focuses on an analysis of behaviour of a dynamic mass measurement system. The goal of this paper is to propose a dynamic model of the system, which can reproduce dynamic behaviour to floor vibration. The dynamics of our system with electro-magnetic force compensation is approximated by a mass-spring-damper system, and an equation of motion is obtained. Model parameters are also estimated from experimental data. Then, comparisons of the proposed model with the previous model are carried out, and the effectiveness is also confirmed.
