A Design Method and Application of Measuring Block Based on Adaptive Algorithm

Abstract

The invention relates to a design method and application of a measuring block based on an adaptive algorithm, which belongs to the field of metrology. The measuring block uses an adaptive computer algorithm, fully considers the electric weighing range of the volume comparator, and measures the weight of the mass comparator. The design parameters such as the size and height of the station, the height of the weight exchange frame of the volume comparator, and the maximum weighing capacity of the volume comparator, etc., also consider the density value and actual mass value of the weight to be tested and the standard weight, and determine the weight used to stabilize the weight. The processing parameters of the groove, so as to design the measuring block suitable for the measuring weight. When measuring, the weight to be measured is placed horizontally on the measuring pad, and the volume of the weight to be measured is obtained by using the hydrostatic method to measure the volume. The design method of the present invention is simple, and the accuracy of weight measurement is improved, especially It is to place the weight horizontally, reduce the bubble adhesion phenomenon in the groove at the bottom of the weight, improve the accuracy of volume measurement, and expand the use range of the volume comparator.

Description

technical field [0001] The invention belongs to the field of measuring instruments, and in particular relates to the design and application of a measuring block used for measuring the volume of a weight in a volume measurement system based on a hydrostatic method, in particular to a design method and application of a measuring block based on an adaptive algorithm . Background technique [0002] Density of an object: It is the quotient of the mass of the object divided by its volume, and the formula is ρ=m / v. Since the mass measurement of the weight is carried out in the air, according to Archimedes' theorem, the buoyant force on the object is equal to the mass of the gas (liquid) it displaces. Therefore, for high-accuracy mass measurement, it is necessary to know the volume of the weight to be tested in order to perform air buoyancy correction and obtain its accurate mass value. According to the international recommendation R111 (version 2004) and JJG99-2006 "Weight" verif...

Problems solved by technology

For 1kg weights of low-density materials (such as aluminum alloy) and other materials, or weights of different shapes (hollow, spindle-shaped), these special-shaped weights are common types of weights in mass scientific measurement , however, its height exceeds the scope of use of volumetric comparators, which greatly limits the scope of use of volumetric comparators. Since these volumetric comparators are all imported from abroad, if their measurement capabilities cannot be expanded, their application will be limited.
