Title:
METHOD AND DEVICE FOR MEASURING DYNAMIC LOAD
Document Type and Number:
WIPO Patent Application WO/1993/005374
Kind Code:
A1
Abstract:
A method and a device for measuring a load in a dynamic state in which variations such as shaking and vibration occur. With a spring system composing member fixed at one end and made free at the other end, a load is applied to the free end for measuring instantaneous displacement Yi and indirectly measuring a static load We from the equation (a), where Wi = instantaneous load; g = gravitational acceleration; DELTAg(A/L)i = acceleration of the free end obtained from differentiation of displacement Yi performed twice, and k = spring constant. When variations such as shaking and vibration occur in the base for fixing the spring system composing member, a static load We is measured by the use of the equation (b), where DELTAg(G/L)i = acceleration of variation occurring in the base.
