摘要
Abstract
Soft recoil launching technology is an important technical way to reduce the recoil force of the gun.Soft recoil technology is normally achieved by fixed forward-rushing position.Because of the difference of bore pressure,the hydraulic resistance caused by recoil mechanism is remarkable in the process of firing.The moving parts cannot move to the right position normally when the ammunition is changed.In order to improve the performance and adaptability of the soft recoil gun,a soft recoil device with servo controlled adjustable flow port was proposed.By the application of before feedback control during firing,the hydraulic resistance can be adjusted effectively to adapt to multiply types of ammunition through forward-control.Based on the soft recoil launch test data of a conventional recoil device,the particle swarm optimization was used to identify the structural interval parameters.Then,the launching process of the proposed recoil device was simulated by combining the identified parameters and fluid simulation results.The simulation results show that the recoil mechanism can make the soft recoil gun work normally and stably under the condition of the different ammunition.The recoil force can be controlled within 400 kN,which meets the design requirements.Therefore,the new recoil mechanism has good adaptation for soft recoil firing of multiply types of ammunition,and it has great practical value,providing a certain reference for the design and application of the soft recoil gun.关键词
