摘要

A method and apparatus for measuring a load under a dynamic state where variations such as swinging and vibration exist. One of the ends of a member constituting a spring system is fixed with the other end free. A stationary load We is calculated in accordance with equation ##EQU1## by attaching a load to the free end and measuring the instantaneous displacement Yi. In the above equation, Wi is the instantaneous load, g is gravitational acceleration, g.sub.(A/L)i is the acceleration of the free end obtained by differentiating twice the displacement Yi, and k is a spring constant. When a base to which the member constituting the spring system is fixed undergoes variations such as swinging and vibration the stationary load We is determined by ##EQU2## where g.sub. (G/L)i is the acceleration of variation of the base.
