Abstract: In order to detect the electrothermal heating tube internal electrothermal film resistance and the relationship between the two electrode gap, this thesis used design using a testing equipment: The two ends of the measurement period from two electrodes, and the probe spacing can be adjusted ; The two measuring points into hair heat pipe internal contact with the resistive film, using the bleeder circuit, the indirect measuring resistance membrane resistance and the relationship between the two measuring points spacing; then analyze the measurement data, the relationship between the two electrode gap and electrothermal film resistance. The use of such equipment, the measured data, we can analyze the electrothermal film heating pipe internal heating membrane resistance and two measurement of the end head distance is linear change. The linear relationship between the use of electrothermal film heating tube internal electrothermal membrane resistance, can estimate the range of internal electric heating film heating pipe resistance from two the distance between the electrodes, get the change range of heating tube power.

Abstract: This thesis uses a kind of detection method: The two ends of the measurement period from two electrodes, and the probe spacing can be adjusted. Two measuring end head into the interior with electric heat pipe membrane contact ,used the voltage dividing circuit,relations indirect detection of electric resistance film ends with the two measuring pitch. Then the measured data analysis, obtains the relationship between the two electrode spacing and the electrothermal membrane resistance. Make this thought method may not be used to measure the electric heating film resistance, become a simple and practical method for measuring the electric heating film resistance. Using this method, the measured data can be analyzed, indirectly electrothermal film heating pipe internal resistance value and the two measurement of the end head distance is linear change. The linear relationship between the use of electrothermal film heating tube internal electric heating film resistance, the resistance can be estimated from the distance between the two electrodes, get the change range of heating tube power.

Abstract: According to the difficulties encountered polishing Non-circular busbar axisymmetrical workpiece, analysis of Non-circular busbar axisymmetrical workpiece polishing requirements, proposes a new model of flexible polishing machine. Then according to the control precision and the developing cost into consideration, determine the "PC+ motion control card" as a form of structure of control system for polishing machine. In this paper, through the analysis of the polishing machine model, established the polishing machine control functions and tasks of each part, formulated the overall hardware frame of polishing machine control system. Then accrod of the polishing function in the program, using vc++6.0 development of form a complete set of application software. In the process of software development, The polishing machine control system operation platform for Windows xp, Using the object-oriented and modularized programming technique, designed and developed Man-machine interface , the initialization module, status display module, parameters setting module, operation module, fault diagnosis module and so on, each part is independent and interrelated, and through calling the dynamic link library. to control the GT400SV motion control card directly.

Abstract: t is need to experiment to verify the correctness and validity of various stages in system design after gauge visual detection system designing between high signals and contact net. Then it does error analysis from lighting conditions, camera resolution, binocular imaging system installation structure, camera out of synchronized, noise and subsequent image processing operations, etc. It analysis the systematic errors principle and specific impact, then identifies specific improvements.

Abstract: The primary parameter of the track circuit is often the test data in the maintenance of the signal, is the important basis for designing equipment of track circuit and is the basic parameter of track circuit parameter, primary parameter of track circuit can be used for rail simulation experiment of track circuit parameters, analysis of rail leakage and calculation of track circuit. This paper studies the primary parameter of track circuit test method, the result can be used for calculation track circuit parameter.In the practical application, primary parameter of track circuit test can have positive significance in the division of track circuit district and the adjustment of working state.

Abstract: The gauge detection between high signal and contact net is an important part in railway safety production. According to the detection nature, this paper designed a visual detection system to solve the problem of gauge detection between high signal and contact net. Using template matching method to break up the gray target image, and using discovering turning point method to rebuild target in space. Then according to the principle, it prepared detection system based on VC++2008 and OpenCV. The experiment results showed that: measurement error was within士15mm, when detection distance was arrange from 45.0m to 55.0m. Detection system which had high accuracy and good reliability, met system design requirements.

Abstract: Traditional coating shell marking process is complex, has long production period, high labor intensity, and endangers health. In order to solve these problems, this paper studied and designed a kind of automatic production line of precision molding in coating shell making process. The production line was controlled by a single-chip microcomputer to automatically achieve the process of dipping, sanding, hardening and drying. It not only improved work efficiency and saved labor, but also reduced the body harm of workers.

Abstract: It plays an important role to detect gauge between high signal and contact net in railway safe, to provide safe guarantee for railway workers. This paper proposed a visual detection model to solve the problem of gauge between high signal and contact net. Base on three-dimensional reconstruction high signal and contact line with space points, it transformed two objects coordinate, then analyzed the position relationship and accurately solved the shortest distance from high signal to contact line, last compared with the standard gauge to achieve the process of gauge detection.

Abstract: E-ACE material membrane drive is studied. Firstly, the three existed strain energy function model are analysised by theroy under uniaxial tension and biaxial tension，then building model and simulation study for it with ANSYS software to compare to experimental results. The result indicate that their curve are almost same.

Abstract: Study on the preparation processing of E-ACE.By experimental methods, the conductivity, the mechanical flexibility of the electrode material and the thickness of the acrylic polymers were studied respectively. Experimental results show that the conductivity of electrode material have an impact on the performance of E-ACE, E-ACE performance is enhanced with the increasing of conductivity of the electrode material. Mechanical flexibility of Electrode materials and thickness of acrylic polymer have significantly impact on the performance of E-ACE, E-ACE performance is enhanced with the decreasing of mechanical flexibility of electrode material, and E-ACE performance is also enhanced with the decreasing of the thickness of acrylic polymers.
