Abstract: This paper conducts a thermal-demagnetization analysis of the concentric eddy current recoil brake (CECRB) for artillery and investigates the resulting degradation in CECRB performance due to temperature rise. The barking force is generated using permanent magnet (PM) and is significantly affected by the temperature and external field. First, the demagnetization characteristics of the permanent magnet were obtained through hysteresisgraph with thermal insulation measures. Then, this paper developed a dynamic link library to establish an irreversible demagnetization model considering the temperature based on the experimental data. Subsequently, to calculate the temperature field distribution of the CECRB, the interior ballistic equation is solved using the fourth-order Runge–Kutta method to obtain the temperature of propellant gas. The friction between the projectile and the inner wall is also considered as the heat source. Lastly, this paper analyzes the influence of temperature on the dynamic magnetic field variation when the CECRB is working. The results show that the braking force decreases by 36.55 % after the first rapid firing. This study presents considerable potential for further research on the design and optimization of the CECRB.
