Radar simulator is a special important instrument in the field of radar test, but the current for the fidelity of the echo of radar simulator validation study is in its infancy. In this paper, the research object is the target’s Doppler, and the simulator fidelity measured by two methods: numerical computation and computing eigenvalues. And the two calculation methods are described in detail on the concrete steps and key issues.

Design of Light Moisture Tester and its Application in Tiefa Coal Industry Group
Authors: Su Hui Long
Published: December 2014

This paper introduces the research and design of a light moisture tester. In the coal quality analysis field, moisture test most of the use of infrared heating pipe heating or drying box to measure, low heating rates, nitrogen through a single mode, before heating furnace uniform nitrogen filled with test conditions and have the test conditions, the same way caused by nitrogen, nitrogen waste. Based on this study, the heating pipe comprises an infrared tube into a light tube, the heating rate is improved; the general nitrogen control size flow switching mode using 2.5min before the experiment, large flow quick heating furnace filled with nitrogen, achieved through experimental conditions drying nitrogen, open a small flow, keep the atmosphere. The improved design of a light moisture meter analysis of water air drying method precision test, analysis of water air drying method accuracy experiments, 6 water - air drying method of precision experiment, 6 water - air drying method accuracy experiments, analysis of water through nitrogen drying method precision experiment, analysis of water. Nitrogen drying method accuracy experiments, Ȼ 6 full water through nitrogen drying method precision experiment, Ȼ 6 full water through nitrogen drying method accuracy experiments, results in line with national standard test, repeatability. Instrument for field application test in Tiefa Coal Industry Group, good test effect.

Published: December 2014

This paper divides the platform performance into three different aspects: general characteristics, hull property and concealment performance, from which we fully study the various factor index involved, use the AHP to build an integrated-assessed mathematic model of hierarchy of good distinct and structure of high efficiency and calculate the weight assessment indicator of each hierarchy. This paper uses AHP to build the general objective function of the designing scheme of platform property. By the statistical analysis of the tip of various property indexes of mass hull property data, we choose the corresponding subordinating degree functions in the fuzzy mathematic field to determine the appropriate subjection function, calculate the relevant degree of membership, and finally conduct the integrated assessment of mathematic model of the design of AUV platform performance system. We use C# language in the developing environment of VS2010 to develop the fuzzy-comprehensive-assessment software system of the designing scheme of AUV platform, and, we also use the software to analysis the systematic reliability of this scheme by living example. Through this work, we could offer a scientific and rational theory of technology for the support of underwater unmanned vehicle research department.

Published: December 2014

Regional coverage monitoring for structural deformation remains a challenge for current technologies. A coverage regional monitoring method based on dual ultrasonic transceivers and exhibiting deformation location ability is presented. The spatial projecting model of dual ultrasonic beams is established to determine the monitoring scope of the structural surface in space. Deformation location principles are induced by analyzing the spatial relations of the monitoring data of dual ultrasonic transceivers. Finally, an experiment is proposed to illustrate the method.

Published: December 2014

This paper introduces a design of testing machine that could apply to the clamping tensile test for explosion-proof cable gland and a clamping tensile test for explosion-proof cable that based on this machine. The tension conduction system composed by wire rope and pulley supplies the test device for cable gland with tension by using standard weights counterweight. In order to ensure test precision, the testing machine loading platform can translate along the horizontal orthogonal direction X, Y and rotate around the X axis to adjust the sample space coordinates. The stress-strain sensor can measure the tension value, and the amount of displacement of the specimen can be measured by dial indicator. This paper focuses on the levelness-adjustable system and test methods.
