Abstract:
To further study the rigid-flexible coupled features of an individual soldier automatic weapon,a virtual prototype is built by a simulation software—ADAMS.The kinematic and dynamic characteristics of the automatic mechanism as well as the influence of the clearance between movements on the dynamics of the automatic mechanism are also analyzed.The results show that the framework design of the individual soldier automatic weapon is reasonable and reliable.Due to the existence of the clearance,the impact between the movements causes the loss of energy,and the x-velocity of the bolt carrier is different from the velocity in the ideal situation.Under the ideal conditions,the velocity is higher and the cycle is shorter,while the clearance is considered in simulation,the situations are contrary.The variation of the bolt carrier velocity curves demonstrates that the clearance has obvious effects on the kinematic and dynamic characteristics of the automatic mechanism and it is necessary to consider the clearance between movements in the course of individual soldier automatic weapon simulation and design.
