In this paper, the circuit model of 1000A/75mV shunt was calculated based on field-circuit coupling method by designing an interactive computer program between numerical analysis in MATLAB and finite element analysis in ANSYS. The calculate results provide the basis to analyzing measurement results when measuring transient current or alternating current with shunt.
There were measuring errors when the inconstant currents are measured with shunts, because the skin effect increased the resistance and decreased the inductance. This paper has analyzed the circuit model of shunts with different frequency by using field-circuit coupling method and the analysis results have been validated by experiment. This paper provided a more accurate engineering method to analyze...
The saturated silt ground in this area which was exerted by seismic loads was simulated numerically by using FLAC-3D. Liquefaction in surface of powder foundation occurred less likely and with the increasing depth of foundation it occurred more likely. The density of soil in upper layer increased because of the role of dynamic compaction. And as density increased, the dynamic strength of soil in this...
