Design for assembly ( dfa ) is an important enabler in concurrent engineering 摘要面向裝配的設(shè)計(jì)是并行工程中的一項(xiàng)重要的使能技術(shù)。
Visual assembly simulation is one of basic key technology of the study of design for assembly ( dfa ) 可視化裝配仿真技術(shù)是dfa研究中的基礎(chǔ)關(guān)鍵技術(shù)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這一術(shù)語,最早是由美國馬薩諸塞大學(xué)( universityofmassachusetts )的gboothroyd和p . dewhurst提出的,當(dāng)時(shí)主要采用的是計(jì)算評(píng)分的方法來對(duì)產(chǎn)品的可裝配性進(jìn)行定量的評(píng)價(jià)。
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 應(yīng)用并行工程的關(guān)鍵技術(shù)之一? ?面向產(chǎn)品全生命周期的設(shè)計(jì)dfx中面向功能的設(shè)計(jì)dff 、面向裝配的設(shè)計(jì)dfa和面向制造的設(shè)計(jì)dfm的方法,在catiav5中完成液力變矩器虛擬設(shè)計(jì);在catiav5中對(duì)液力變矩器進(jìn)行虛擬加工建模和仿真,包括液力變矩器導(dǎo)輪葉片五軸數(shù)控加工刀軌建模與仿真、導(dǎo)輪快速成型rp建模( pvc材料) 、液力變矩器虛擬裝配和運(yùn)動(dòng)仿真等;采用step標(biāo)準(zhǔn)實(shí)現(xiàn)多cad系統(tǒng)之間三維數(shù)據(jù)交換,提出液力變矩器特征模型的分級(jí)標(biāo)準(zhǔn)并對(duì)三維模型數(shù)據(jù)進(jìn)行分級(jí)管理,制定相應(yīng)的權(quán)限等級(jí)以規(guī)范合作廠家的產(chǎn)品數(shù)據(jù)管理層次。
