Design method used for measurement cushion block and based on adaptive algorithm as well as application

Abstract

The invention relates to a design method used for a measurement cushion block and based on an adaptive algorithm as well as an application, and belongs to the field of metering. The adaptive computer algorithm is utilized, design parameters such as electric weighing range of a volume comparator, size and height of a measurement station of a mass comparator, height of a weight change frame of the volume comparator, maximum capacity of the volume comparator and the like are fully considered, density values and practical mass values of a to-be-measured weight and a standard weight are further considered, and processing parameters of a groove used for stabilizing the weight are determined, so that the measurement cushion block matched with a measurement weight is designed. During measurement, the to-be-measured weight is horizontally put on the measurement cushion block, volume measurement is performed with a liquid static method, and the volume of the to-be-measured weight is obtained. The design method is simple and improves the weight measurement accuracy; particularly the weight is horizontally arranged, so that air bubble adhesion phenomena of the groove in the bottom of the weight are reduced, the volume measurement accuracy is improved, and the application range of the volume comparator is expanded.

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.
