摘要: Range Extended Electric Vehicle (REEV) is a vehicle in smooth transition to pure electric vehicle. According to the functional analysis to REEV, propose the overall design of auxiliary power unit, develop an APU control system. This control system is based on infineon XC164CS Single Chip Microcomputer, use modular method, design and develops the data acquisition module, IGBT driver module, CAN communication module and conducts bench experiment to the system. The bench testing shows the system has high sampling precision, fast speed, good stability and easy to debug. Basic APU strategy control plan is designed to ensure electricity generation with first constant current, then constant voltage work mode, and can perform the fault diagnosis function, meet practical requirements, and achieve the expected control purpose.

摘要: The quality of thread will directly affect the reliability of mechanical system, and the accuracy grade of geometric parameters is the judgment standard to thread quality. Thus, its particularly important to detect the geometric parameters of thread. Its a pretty mature and widely used method to measure thread parameters with universal tool-measuring microscope, but it has many shortcomings, such as tedious operation, low efficiency and the reading error. In view of the above shortcomings, the paper does some simple refits to the existing 19JA universal tool-measuring microscope. In order to improve reading speed and accuracy, the grating rulers are installed on the operating platform in two directions. CCD camera is used to get external thread image instead of human eyes and the eyepiece, which is a non-contact measurement method. A software that based on MFC of VC + + 6.0 is written, which can deal with the thread image and get the thread parameters. The experimental results show that the method can not only effectively improve the measurement efficiency but also guarantee the accuracy of measurement.

摘要: The paper is devoted to the simulation of queueing networks on high performance computer clusters. The objective is to develop a mathematical model of queueing network and simulation approach to the modelling of the general network functionality, as well as to provide a software implementation on a high-performance computer cluster. The simulation is based on a discrete-event approach, object oriented programming, and MPI technology. The model of the queueing networks simulation system was developed as an application that allows a user to simulate networks of rather free configuration. The experiments on a high performance computer cluster emphasize the high efficiency of parallel computing.
