load balance measurement

Abstract

The invention provides load balance measurement and a measurement device. The load balance measurement comprises a rigid load adder, a first load, a second load, an inertial reference system, a system balance force, and a force sensing element, wherein the rigid load adder is used for adding and transferring a rigid body or a non-absolute rigid body with acting effects by the load; the inertial reference system enables the rigid load adder to be kept still in relative to the inertial reference system; the system balance force is provided to the rigid load adder by the inertial reference system for an acting force for enabling the rigid load adder to be kept still in relative to the inertial reference system; the force sensing element is used for adopting a contact or non-contact mode to execute measurement on a positive direction value of a single component acting force, a negative direction value of the single component acting force or two direction force values or force value changes; acting effects by the first load, the second load and the system balance force on the rigid load adder are added by the rigid load adder; and the system balance force provided by the inertial reference system for the rigid load adder is measured by the force sensing element.

Problems solved by technology

It has never been able to go deep into the interior of the force system to explore the internal balance state and force condition of the force system; coupled with the constraints of the small range, high-precision measurement characteristics and low resolution of non-contact measurement of the existing detection devices, the existing mechanical measurement methods There are still some deficiencies in the measurement of the limit range, and no breakthrough has been made in the accurate determination of the above mechanical problems in this type of test.
