NX软件在某天线架模态响应中的应用

内容简介：根据工程实际,利用NX软件对某天线架进行模态分析,并详细地介绍了利用NX软件进行仿真的过程。在NX中建立天线架的三维模型,进行模态响应分析,计算模态和应力分布,根据仿真分析结果,进行结构优化设计,提高谐振频率,使各项机械性能指标满足设计要求。

Abstract：According to the engineering practice,this paper uses NX software to perform mode analysis to a certain antenna frame,and introduces the course of simulation by using NX software in detail.The 3-D model of antenna frame is set up in NX and the mode respond analysis is performed,the mode and stress distribution are calculated,according to the simulation analysis result,the structure optimization design is performed,the resonance frequency is improved,which makes each mechanical performance indexes to satisfy the requirement of design in this paper.
