In order to obtain the efficiency and energy distribution of 2-turn plane augmented linear drive

the field circuit collaborative analysis method was selected

and the pulse high current linear drive model was established based on the MATLAB Simulink and COMSOL platform. The reliability of the calculation model was verified by the experiment data.The model can be used to simulate the important parameters such as inductance gradient and resistance gradient of the driving device

as well as the conversion efficiency

exit velocity

and energy distribution of the drive

which provides an efficient and reliable calculation model for structural optimization. According to the calculation results

it can be found that the electrical parameters of the drive are not only affected by the current frequency

but also related to the current amplitude. Among the input energy of the drive

the most energy distributed in the rail is about 50%

most of the energy is converted into Joule heat

about 54.15%

and only 27.76% of the energy is converted into the kinetic energy of the armature.
