摘要
为验证某型车载速射迫击炮上架设计的合理性,利用Abaqus有限元软件,对车载速射迫击炮上架有限元模态进行分析。采用等效质量的方法,在Solidworks中建立上架3维模型,通过对上架及自动机和高低机的装配体结构进行有限元模态分析,计算出其前20阶的固有频率和振型。研究结果表明:该设计是合理的,能避开迫击炮的射击频率,可为上架的进一步结构优化及武器试验基地的射击试验提供参考。
In order to verify the rationality of the design of certain type vehicle-borne rapid-fire mortar,the Abaqus finite element software was used to analyze the finite element mode of the vehicle-mounted rapid-fire mortar.Using the method of equivalent mass,a 3-D model was built in Solidworks.The finite element model analysis of the assembly structure of the upper frame,the automaton,the high and low machine,and the first 20 order natural frequencies and vibration modes were got.The research results show that this design is reasonable and can avoid the firing frequency of mortars.It can provide reference for the further structural optimization of the upper frame and the firing test of the weapon test base.
