【摘要】 将CAE(计算机辅助工程)仿真技术运用于MP3产品从概念设计到细致设计的过程,在产品设计的初期阶段就能够预测产品的结构设计是否符合国家对电工电子产品的环境试验标准规定。而自由跌落作为消费性电子产品MP3环境试验的一个重要试验项目,其属于实物试验,大多在产品开发后期进行,采用计算机仿真技术可在MP3新产品开发初始进行自由跌落响应分析,能够有效地发现设计缺陷。通过运用HyperMesh/Ls-Dyna软件就MP3整体模型进行与实物试验手法完全相同的自由跌落试验仿真分析,验证产品结构设计的可靠性,从而发现可能会出现的质量问题,达到缩短产品开发周期,降低成本的目的。更多还原

【Abstract】 To apply CAE technology to the design of a mobile phone product from idea to particularity,in the prophase of product development.The engineer can dope out the design of the whole product or each component whether accords with the normal regulation for environmental examination of electronic products in the country.The free-drop examination with practicality is a vital item of environmental examination of mobile phone products,it demands the examination of existence,generally speaking,the examination is always performed in the anaphase of product development.With CAE technology,the free-drop response of a mobile phone can be simulated before manufacturing,and the flaws in design can be knowed.Based on HyperMesh/Ls-Dyna software,a main job of simulation,for the functional effect of the round radius to the wall thickness in the strength and stiffness as mobile phone,through the contrast and analysis of the data,the universal reference in the round radius design is gained.更多还原
