Abstract

In order to study the dynamic characteristics of magnetorheological active buffer of automatic grenade launcher, the buffer model of the compound working mode of magnetorheological buffer and spring under launch load was established. The particle swarm optimization algorithm with adaptive weight was used to optimize its structure, and the magnetic field before and after optimization is verified by finite element method. The output damping force of the buffer under different current states was analyzed, and the dynamic characteristics of the buffer under emission load are obtained. It is found that under the launch load, the magnetorheological buffer has faster response speed, better platform effect and larger damping force adjustment range than the spring hydraulic buffer. The good dynamic characteristics of the spring magnetorheological buffer can effectively and quickly weaken the impact of the weapon during firing and improve the shooting adaptability and accuracy of the weapon in the complex environment.

Key words： automatic grenade launcher; magnetorheological buffer; dynamic characteristics
