    Abstract
  • Transient resistance is one of the most important parameters in the process of electric explosion.The accurate description of the nonlinear time-varying characteristics of the exploding wire resistance is the key to the simulation of electric explosion, which determines the simulation precision.In order to solve the problem of poor precision associated with traditional simulation model, this paper presents a piecewise calculation method based on current density to correct the relationship between traditional resistivity and specific action, and establishes a piecewise calculation electric explosion simulation model based on the current density.The results show that, under the condition of large pulse current, the precision of the model is higher than that of the traditional simulation model, which can be used to study the electric explosion process with high accuracy.
