Temperature Rise and Electromagnetic Force Characteristics of Electromagnetic Brakes Under the Coupling of Magneto-Thermo-Force

It operates in a Magneto-Thermo-Force coupling environment, when the electromagnetic brake is applied to artillery. The intensive impact force and the temperature rise will both affect the magnetic and mechanical properties of the electromagnetic buffer, thereby affecting its damping characteristics. In this paper, the temperature demagnetization and shock demagnetization models of the electromagnetic brake were first established through experiments and simulations. Then, a Magneto-Thermo-Force coupling model of the electromagnetic brake was established using finite element software to analyze and calculate the temperature rise and electromagnetic damping force. Finally, a large caliber artillery experimental system was designed and tested, and the experimental results verified the reliability of the model. The established finite element computing model provides a fast and accurate calculation method for the multi field coupling analysis of the electromagnetic damping brake, which is of great significance to the study of Magneto-Thermo-Force coupling characteristics during recoil motion.
