According to biological immune danger theory, a condition monitoring algorithm based on immune danger theory was presented. In the algorithm, the whole diagnosis feature space is divided into danger feature space, normal feature space and abnormal feature space. The algorithm consists of primary testing module, APC testing module and self-adapting testing module. The algorithm can make judgment according...
A new cross flow solid-liquid separate equipment with high efficiency has been proposed, and comparative experiment investigations between the municipal sewage plant and the test device of the separator and the numerical simulation of the device flow field using FLUENT CFD software have been combined to define its basic operating parameters and precipitation characteristics, and has laid the foundation...
The brake system is the safety-critical subsystem of rail transit vehicle. However, the reliability test technology related to rail transportation equipments is much needed in China. In this paper, a certain Chinese computer-controlled electro-pneumatic brake system was selected to conduct reliability analysis by FMEA and BCEU (Brake Control Execution Unit) was determined the weak link of the brake...
The technology of testing fuel economy is not only a comprehensive parameter for evaluating the level of cars' technology and maintenance, but also an important reference for diagnosing and analyzing the troubles of cars. Using the method of Ultrasonic Flow Detection to measure the fuel consumption, this essay is based on a comprehensive comparison of several traditional fuel economy detection systems...
