基于ANSYS的某型高射机枪有限元分析

Finite Element Analysis of Certain Type of Antiaircraft Machine Gun based on ANSYS

基于结构动力学理论,运用有限元分析软件ANSYS建立了某型高射机枪三维实体有限元模型,通过试验验证了模型的可信性,并研究了其结构动力学特性,通过模态分析找出了对武器射击精度影响比较大的结构单元,为该枪动力修改奠定了基础。

Based on the theory of structure dynamics,the paper built the finite element model of 3D entity by means of finite element analysis software of ANSYS.In the paper,it validated the creditability of model through experiment result,and also researched on the characteristic of its structure dynamics.By dint of modal analysis,the paper found out the structure unit that would influence the weapon shooting precision obviously.The result provides a base for motive power modification of the antiaircraft machine gun.
