[Abstract]:As the basic power unit of the turbine drilling tool, the blade shape parameters of the turbine drill tool directly determine the dynamic performance of the turbine drilling tool. In order to test the rationality of the turbine drilling tool stator and rotor blade design, and reduce the test cost. It is necessary to use less series of stator and rotor to test and predict the performance of turbine drilling tool. Therefore, in order to meet the needs of scientific research and production. The main purpose of this paper is to develop a computer automatic acquisition and monitoring system, which is suitable for a series of new turbine drilling tool stator and rotor performance testing system. Firstly, based on the basic theory of the testing system, combined with the current research situation and the field conditions of the performance testing of turbine drilling tools, the research work of the performance testing system of turbine drilling tools is carried out. On this basis, the working principle and function of the turbine drilling tool stator and rotor performance test system are studied theoretically, the conversion formula of the whole machine performance and the conversion formula of the performance parameters under different flow rate are deduced. The technical requirements and performance characteristics of the test system are determined, and the research contents are divided into mechanical structure design, measurement and control part development and real machine test test to carry out further research work. Secondly, according to the principle of mechanical drawing and mechanical design, the whole mechanical structure of the test system is designed, and the drawing of all parts engineering drawings is completed by using AutoCAD. The main parts are selected, designed and analyzed. The static and dynamic characteristics of the spindle are analyzed by SolidWorks and Workbench, and its deformation, stress distribution, natural frequency and mode are studied. In order to ensure the safety and stability of the test-bed during the test, the critical speed harmonious response analysis is carried out. Thirdly, the design and development of the measurement and control part are carried out, and the connection design and type selection and calibration of each measurement and control unit are completed. The test software is developed by using the dynamic link library written by LabVIEW2012 and VC, which is divided into data acquisition module and curve output module. An anti-jamming scheme is also proposed to improve the accuracy of the test. Finally, the whole assembly and performance debugging of the performance test system of turbine drilling tool stator and rotor are completed. According to the actual working conditions, the detailed test scheme and steps are designed, and the stator and rotor of 桅 127 turbine drilling tools with two kinds of blades are selected to test and test. The content and data of the test are analyzed, and the performance curve is drawn. The test results show that the test system developed in this paper is stable, accurate and easy to operate. It provides a complete and effective solution for testing the performance of turbine drilling tools and checking the correctness of its blade shape design.
