In view of the fact that the material thickness of grate cooler system is difficult to measure, we present a new method of modeling that takes advantage of genetic algorithm to optimize the BP neural network and has a contrast with the pure BP neural network. Simulation shows that the BP neural network model which is optimized by genetic algorithm has a small error. At the same time, it is more stable...
Due to difficulties and inconveniences in storing and transporting of high-pressure pure hydrogen, hydrogen source becomes one of the technical bottlenecks of the commercialization of fuel cell. In this thesis, a compact autothermal reformer suitable for liquid fuel was developed. The fuel processor consists of a fuel evaporating step, two-stage reformer and a two-stage reactor of water gas shift...
Based on finite element method and ANSYS software, vibration feeder is fatigue break influenced by exciting force alternate load. This paper introduces the rational finite element model of vibration feeder. It discusses harmonic response analysis and discovers weak links which is angle steel junction of side plate, feed inlet and junction panel between no feed side plate and bottom plate then makes...
Rotor is the major work components of vertical shaft impact crusher and tip set extra hard is the most wearing part of it. Based on the analysis of the structure and the working principles of the vertical shaft impact crusher, we set up the three-dimensional model of the rotor in Solid Works. Through the importation of the 3-D model into ADAMS for the dynamic simulation, we simulate the throwing process...
A novel series feed network based on CRLH-TL is proposed. Even amplitude can be achieved by using cascaded 3-port power dividers which are composed of lambda/4 transformers, exponential transformers and single-stub tuners. Meanwhile, adjusted CRLH-TLs are introduced to compensate the phase delay caused by the different length of traditional RH-TLs, and consequently even phase distributions among all...
