Research On The Small-scale And High-precision Measurement Methods And Equipment For Integration Of The Mass Properties

Mass property of measuring equipment for measuring the Mass, center of mass, moment of inertia, Product of inertia and other Mass property parameters of special equipment. With the miniaturization of certain types of weapons to the trend, the Mass property parameters of the measurement accuracy is also becoming more demanding, and also requires the measurement of Mass property parameters become integrated.This article according to Zheng-zhou Research Institute of Mechanical Enginery, has not developed specific implementation of the latest patents, the mass and the mass center of the integrated measurement studies; and structural analysis and refinement, design and development of mass and mass center integrated measurement equipmentThe mass center measurement breakthrough in the traditional measurement mode, instead of gravity axis with the axis of rotation as the benchmarks, it can be measured and adjustable with the advantages, making the mass center measurement benchmarks and the axis center measurement benchmarks are to be uniform. This technology support on the sensor than itself measurement method, and it instead of the traditional between the sensor data processing, this eliminates the error of the sensor range, resulting in improved measurement accuracy.By measuring principle analysis, mechanical structure design, software design, prototype assembly debugging and actual measurement applications, the formation of a high-precision measurement technology integration the mass and center of mass.In this thesis, moment of inertia based on the measurement equipment, designed a test fixture, to solve three-dimensional measurement of moment of inertia of the integration problem. Based on the standard sample measurement of three-dimensional moment of inertia, and its error analysis, and proposed measures to improve the measurement accuracy.Studies of the moment of inertia and product of inertia of the integrated measurement, measuring principle based on inertia ellipsoid, and measure the standard sample and productions of product of inertia. Finally, the measure of product of inertia of the inertia ellipsoid method and the vertical precision dynamic balancing method was compared and synthesize application of contrast, to find their own measurement features and application range.The mass and center of mass integration of measuring equipment and moment of inertia measurement device debugging is completed, and both for practical engineering applications. Measuring the mass and center of mass of An Min productions, China Electronics Technology Group Corporation 27 production of moment of inertia. The measurement method has been recognized by customers, measurement accuracy of productions make customer satisfaction.In this thesis, test fixture using AutoCAD design tooling; and using SolidWorks drawing a three-dimensional entity structure diagram, and made use of COSMOSWorks finite element analysis of rotating axis. The use of Visual Basic programming language, write a Mass property parameter measurement procedures and the corresponding user interface.
