Research on Multi-Field Coupling Simulation of Pulse Current Shunts

摘要

Pulse shunt is stable with simple structure and good linear property, and it is of wide application in pulse power technology and electromagnetism. In this paper, the coupling simulation of electromagnetic field, structure field, fluid field and temperature field of pulse shunts is achieved by multi-field coupling method. The influence of the pulse shunts geometry on the distribution parameters is obtained. This method has better calculation accuracy on heat loss, electromagnetic force and deformation contrast to tradition methods. The analysis of the pulse shunt on working state is of guiding significance for the prediction and optimization of its performance.
