Measurement method for differential vertical micro force measurement device

Abstract

The invention discloses a measurement method for a differential vertical micro force measurement device. The differential vertical micro force measurement device is characterized in that a primary fulcrum is set in the middle of a primary lever arranged horizontally; a pair of secondary levers are symmetrically arranged at two sides of the primary lever in the same vertical plane with the primary lever as a center; the respective side is connected with the primary lever through a primary transition rod; and the pair of secondary levers are respectively connected with a tertiary lever at the respective side through a secondary transition rod. The measurement method for the differential vertical micro force measurement device can provide support for a force measuring system for micro force values.

Problems solved by technology

But the measurement system of tiny force value has not been established yet, so far, 10 -5 A traceable measurement method for micro- and nano-newton ultra-small force values ​​below Newton has not yet been established, so it is particularly important to develop an easy-to-use, low-cost micro-force value measuring and testing instrument to measure micro-force in various occasions

At present, micro-force measurement mainly includes piezoresistive, capacitive, piezoelectric, etc., piezoresistive force measurement is a force measurement device prepared by using the piezoresistive effect of piezoresistive materials, but this method is easily affected by temperature; The piezoelectric microcantilever type is easy to be interfered by the electromagnetic field, and the force measurement cost of the piezoelectric microcantilever is low, but the operation is inconvenient and the measuring range is small

[0004] At present, the flexible hinge mechanism has been widely used in the fields of precision measurement and calibration, but there is no good solution to the influence of the deformation of the flexible hinge, the position of the center of gravity of the lever, and the change of temperature on the accuracy of measurement and calibration. When calibrating or measuring, in order to obtain higher accuracy, the influence of the above aspects on the calibration or measurement of micro-force must be resolved. The influence of gravity and temperature may be far greater than the maximum range of micro-force calibration or measurement. For micro-force calibration or measure fatal effects
