In this paper , we discussed the similarity between machine design process and biology growth process , especially the similarity between machine structure design process and biology embryo growth process , and point out that we should use the rule of biology embryo growth process ( morphogenesis ) to implement assembly structure design automation , and put forth a feasible plan to implement the assembly structure design automation 摘要論述了機(jī)械設(shè)計(jì)過程與生物發(fā)育過程之間的相似之處,特別是機(jī)械結(jié)構(gòu)設(shè)計(jì)過程與生物胚胎發(fā)育過程之間的相似性,指出借鑒生物胚胎發(fā)育的規(guī)律(形態(tài)發(fā)生學(xué))實(shí)現(xiàn)裝配結(jié)構(gòu)設(shè)計(jì)自動(dòng)化的可能性,并從計(jì)算機(jī)實(shí)現(xiàn)的角度提出了可行的步驟和方案,利用此方案可實(shí)現(xiàn)裝配結(jié)構(gòu)的自頂向下設(shè)計(jì)。
