新型卡铁偏转式闭锁机构设计与动力学仿真

Design and Dynamic Simulation of the New Locking Mechanism of Lock-Iron Deflection Type and Dynamic Simulation

通过对闭锁机构工作特性的分析,在12号霰弹的基础上,设计了一款新型的卡铁偏转式闭锁机构.利用UG软件对所设计的机构进行三维建模,以闭锁块为研究对象,通过动力学分析建立了闭锁机构动力学微分方程,并运用ADAMS对模型进行仿真.仿真结果表明:闭锁机构能在0.5s内完成开锁,在1s内完成闭锁;后坐与复进的运动特性证明闭锁机构运动协调、闭锁可靠并能复进到位.所建立的卡铁偏转式闭锁机构动力学微分方程,为自动武器闭锁机构的设计提供了一定的理论依据.

On the basis of the 12th canister, designed a new locking mechanism of lock-iron deflection type through the analysis of the working characteristics of the locking mechanism, to improve the re- search on the dynamics of the locking mechanism. Established the 3D model based on UG and selected locking block as the research object, established the dynamics differential equation of the locking mecha- nism through the dynamics analysis and made simulation on the model by using the ADAMS. The re- sults show that the locking mechanism can be completed the unlock within 0. 5 s and lock within 1 s, the motion characteristics of the recoil and reentry proved that the locking mechanism is coordinated, and the locking is reliable and can be repositioned. Dynamics differential equation of the locking mechanism of lock-iron deflection type provides a certain theoretical basis for the design of the automatic weapon locking mechanism.
