Research on Hydrogen Absorption Mechanism Modeling of the NdFeB Hydrogen Decrepitation Process

Abstract:

The behavior of hydrogen absorption in the NdFeB Hydrogen Decrepitation process is affected by the shape of the NdFeB alloy, pressure and temperature curves of the reaction process, which makes the reaction process with characteristics of nonlinear, time-varying parameters and coupling. In this study, we proposed a state space modeling method to describe the dynamic mechanism model of the hydrogen decrepitation process, and determine the main parameters of the model according to the mass balance, energy balance and kinetic equations. Then implemented the simulation model of the hydrogen absorption dynamic mechanism model using the matlab language. The simulation results were compared with the measured data, which verified the correctness of the model.
