Design for assembly ( dfa ) is an important enabler in concurrent engineering 摘要面向装配的设计是并行工程中的一项重要的使能技术。
Visual assembly simulation is one of basic key technology of the study of design for assembly ( dfa ) 可视化装配仿真技术是dfa研究中的基础关键技术之一。
The design for assembly ( dfa ) is an important enabling technology in concurrent engineering . g boothroyd and p . dewhurst of university of massachusetts firstly gave this terminology when they applied a method to evaluate the performance of product assembly design . dfa evaluation method is still developing with the deep research of concurrent engineering Dfa这一术语,最早是由美国马萨诸塞大学( universityofmassachusetts )的gboothroyd和p . dewhurst提出的,当时主要采用的是计算评分的方法来对产品的可装配性进行定量的评价。
Applying the key technique of concurrent engineering - design for function ( dff ) , design for assembly ( dfa ) and design for manufacture ( dfm ) of the method of design for " x " , the virtual design of the torque converter is accomplished in catia v5 . then the model constitution and the simulation of virtual process of the torque converter is done in catia v5 , including the model constitution and the simulation of 5 - aixe nc virtual process of the vane , the model constitution ( material : pvc ) of the idler pulley rapid prototyping ( rp ) and the virtual assembly and the motion simulation of the torque converter , etc . 3 - d data exchange between various cad systems is realized by using step standard . the lever of classing the character model of the torque converter is given 应用并行工程的关键技术之一? ?面向产品全生命周期的设计dfx中面向功能的设计dff 、面向装配的设计dfa和面向制造的设计dfm的方法,在catiav5中完成液力变矩器虚拟设计;在catiav5中对液力变矩器进行虚拟加工建模和仿真,包括液力变矩器导轮叶片五轴数控加工刀轨建模与仿真、导轮快速成型rp建模( pvc材料) 、液力变矩器虚拟装配和运动仿真等;采用step标准实现多cad系统之间三维数据交换,提出液力变矩器特征模型的分级标准并对三维模型数据进行分级管理,制定相应的权限等级以规范合作厂家的产品数据管理层次。
