A new failure model based on Saber platform is proposed to simulate familiar failure mode of analog circuit, such as open-circuit and short-circuit mode. With this new model, it becomes much easier and more convenient to carry out fault injection and failure simulation in analog circuit simulation. By using a representative case, it is validated that the integrated fault model is correct and the injection...
Three-dimensional modeling of mine tunnel is the important content of three-dimensional modeling of deposit, but also an important means to realize the visual expression of underground tunnel, analyze spatial distribution optimization and improve mine production management. Three-dimensional modeling of drainage tunnel can more realistically reflect the real situation. Firstly, the paper analyzes...
In order to accurately construct the modeling of a telerobot in a virtual environment and reduce the work of developing the graphic design, this paper took the XK-II telerobot as a prototype, using SolidWorks modeling and interactive graphics programming with Open Inventor. First of all, we constructed each entities' geometric model in SolidWorks, and then, derived these models into VRML files and...
CLUE-S (the Conversion of Land Use and its Effects at Small Region Extent) Model was used to predict land use and land cover change (LUCC) from 2001 to 2020 in Zhangye City. The modeling built 3 kinds of water amount restriction scenarios. The base map was the land use map from TM image of 2001. 10 kinds of important driving factors of LUCC were chosen by Arcview 3.3. The weighting coefficient of...
The key technology of the advanced variable nozzle turbocharger is the proportional valve control system. In this article, the fundamental dynamic equations of the proportional valve control system for the turbocharger are deduced by analyzing the principle of operation, the mathematical model of the control system is established, and the control system is simulated by using the MATLAB/Simulink. The...
Loop closing operation in distribution network will brings about steady-state loop current and the transient surge current??Recent papers mainly analyze the theory and calculation method of the steady-state loop current, but seldom discuss the transient surge current, only a rough evaluation presented. This paper fully studys the mechanism of occurrence of the transient surge current and establishs...
