然而,通過這些日子以來(lái)的翻閱與設(shè)計(jì)畫圖,我可以說(shuō)是基本上掌握了,可以自行解決一些簡(jiǎn)單的圖形要求設(shè)計(jì)。比如拉伸指令,在做好平面圖拉伸的時(shí)候總是出現(xiàn)錯(cuò)誤,顯示已選擇一個(gè)自相交的平面,不能拉伸。是12小時(shí),也就是12*60=720分,那么一分鐘時(shí)針則是360/720=176。然后,可直接單擊【應(yīng)用】按鈕,第二個(gè)連桿默認(rèn)接地,這樣就完成了一個(gè)旋轉(zhuǎn)副的添加。 裝配完鐘表模型 各配合關(guān)系用鼠標(biāo)右擊表殼,選擇【編輯顯示】,在彈出的【編輯對(duì)象顯示】對(duì)話框中更改透明度,得到表的形狀。得到秒針。這樣便得到了表盤上需要的文字。(3)UG中鐘表夠構(gòu)件的運(yùn)動(dòng)仿真。(6)UG允許制造商以數(shù)字化的方式仿真、確認(rèn)和優(yōu)化產(chǎn)品及其開發(fā)過程。并根據(jù)產(chǎn)品設(shè)計(jì)的形狀特性、精度特性,真實(shí)地模擬產(chǎn)品三維裝配過程,并允許用戶以交互方式控制產(chǎn)品的三維真實(shí)模擬裝配過程,以檢驗(yàn)產(chǎn)品的可裝配性。Unigraphics NX針對(duì)用戶的虛擬產(chǎn)品設(shè)計(jì)和工藝設(shè)計(jì)的需求,并對(duì)其進(jìn)行運(yùn)動(dòng)仿真,提供了經(jīng)過實(shí)踐驗(yàn)證的解決方案。s Unigraphics NX virtual product design and process design requirements, carries on the motion simulation verified through practice and provides the solutions.Article mainly clockwork as the research object, a type of clocks on the parametric virtual design, established the clockwork table, dial, atlas, clockwise, the second minute, 3d model. According to the principle of mechanical clocks and watches by modeling and simulation movement, introduced in parts of the text or calibration methods highlighted by the hands of the clock to add, and makes them according to the given velocity, the speed ratio.Through the virtual assembly, motion simulation, verify the assembly design and operation process and result is correct or not, in order to find the problem of early, assembling, reduce the cost for modification, and through the visualization, and then to achieve precise assembly simulation movement, production efficiency and high quality in real time, low cost, short of the environment, and has a good service.Keywords: UG, parameterized modeling, simulation and movement目錄摘要 1 第一章 緒論 3 3 UG的一些基本應(yīng)用功能 4 : 5 第二章 鐘表設(shè)計(jì)原理及零件造型 7 7 7 7 7 7 7 8 8 8 表盤 9 表殼 16 時(shí)針 17 分針 18 19 本章小結(jié) 20 第三章 鐘表的虛擬裝配 21 21 、分針與秒針 22 24 26 第四章 運(yùn)動(dòng)仿真 27 27 27 28 29 31 32 34 第五章 總結(jié)與展望 35 35 36 36 參考文獻(xiàn) 38 IV基于UG的鐘表機(jī)構(gòu)參數(shù)化設(shè)計(jì)及運(yùn)動(dòng)仿真第一章 緒論 Unigraphics(簡(jiǎn)稱為UG)是美國(guó)EDS公司出品的一套集CAD/CAM/CAE于一體的軟件系統(tǒng)。(2)UG是 UGS PLM 新一代數(shù)字化產(chǎn)品開發(fā)系統(tǒng),它可以通過過程變更來(lái)驅(qū)動(dòng)產(chǎn)品革新。(2)UG是一個(gè)完全的參數(shù)化軟件,為零部
