【正文】 atch conforming meshers (Patch Conforming Tetrahedrons and Sweeping) for solid bodies and any of the surface body meshers.Electromagnetics: The preferred meshers for electromagnetic analysis are the patch conforming meshers and/or the patch independent meshers (Patch Independent Tetrahedrons and MultiZone).CFD: The preferred meshers for CFD analysis are the patch conforming meshers and/or the patch independent meshers. See Method Control for further details.Explicit Dynamics: The preferred meshers for explicit dynamics on solid bodies are the patch independent meshers, the default sweep method, and the patch conforming mesher with Virtual Topologies. The preferred meshers for explicit dynamics on surface bodies are the uniform quad/quadtri meshers or the quad dominant mesher when used with size controls and Virtual Topologies. See the Method Control section for further details. Set Physics and Create MethodThis option sets the Physics Preference for the current Mesh object in the Tree Outline for Mesh ponent systems. It inserts a Method control, sets the scope selection to all solid bodies, and configures the definition according to the Mesh Method that is selected on the panel. To enable this option, you must attach geometry containing at least one solid body and remove any existing mesh controls. Set Meshing DefaultsThis option updates your preferences in the Options dialog box. The Options dialog box is accessible by selecting Tools Options from the main menu of the Meshing application.If a Mesh Method has already been set for the current model and the Set Meshing Defaults option on the Meshing Options panel is unchecked, the OK button on the Meshing Options panel will be grayed out (unavailable). This is because in such cases where the Mesh Method has already been set, the Meshing Options panel would be useful only for setting meshing defaults in the Options dialog box. Thus if you uncheck Set Meshing Defaults, the Meshing Options panel cannot provide any additional functionality and the OK button is disabled. Display This Panel at Meshing StartupThis option controls whether the Meshing Options panel appears at startup of the Meshing application.Meshing Implementation in ANSYS Workbench The meshing capabilities are available within the following ANSYS Workbench applications. Access to a particular application is determined by your license level. Step 12: Animate the five mode shapes. Set the results for the first mode to be animated. 1.

The wing is of uniform configuration along its length and its crosssectional area is defined to be a straight line and a spline as shown. It is held fixed to the body of the airplane on one end and hangs freely at the other. The objective of the problem is to find the wing39。他們是我大學(xué)最好的朋友，馬上就要畢業(yè)了，在此我只想說(shuō)：哥們，謝謝你們！ 最后我還要感謝母校對(duì)我四年的培養(yǎng)，今后的人生我會(huì)再接再厲，爭(zhēng)取做出令人矚目的成績(jī)來(lái)回報(bào)母校，為母校爭(zhēng)光添彩。作為一個(gè)將要畢業(yè)的大學(xué)生最缺乏的就是實(shí)踐經(jīng)驗(yàn)，所以在畢業(yè)設(shè)計(jì)中肯定會(huì)有許多考慮不周全的地方，多虧導(dǎo)師循序善誘的進(jìn)行指導(dǎo)，發(fā)散我們的思維，為我們排解困難，讓我們從中收獲了豐富的知識(shí)經(jīng)驗(yàn)。以后的工作中，我們要學(xué)會(huì)收集和整理材料，能提出問(wèn)題、分析問(wèn)題和解決問(wèn)題，并將其結(jié)果能清晰表達(dá)出來(lái)，然后多向周圍的前輩或者同事請(qǐng)教學(xué)習(xí)，取長(zhǎng)補(bǔ)短。眼高手低是普遍存在的問(wèn)題，就從畢業(yè)設(shè)計(jì)來(lái)說(shuō)，完成好一份較好的設(shè)計(jì)絕非易事，許多知識(shí)使用起來(lái)都很陌生，進(jìn)度很慢?？此坪芎?jiǎn)單的課題，卻讓我絞盡腦汁，才完成設(shè)計(jì)工作，其中或許還有很多不足之處。最終完成設(shè)計(jì)后的整體效果較為滿意，但還有許多改進(jìn)的空間，存在一些不夠完善的地方。與組員設(shè)計(jì)的傳動(dòng)裝置配合而成的取筷機(jī)構(gòu)設(shè)計(jì)是這次畢業(yè)設(shè)計(jì)的重點(diǎn)與難點(diǎn)。后面對(duì)筷子盒底座進(jìn)行了受力的分析研究，結(jié)果達(dá)到要求，設(shè)計(jì)基本完成。 本章小結(jié) 底座設(shè)計(jì)是最后進(jìn)行的，比較復(fù)雜，需要與各個(gè)零件銜接好，符合裝配要求。其中筷子盒重約6kg，即承受筷子質(zhì)量14kg，以足夠日常使用筷子的承載。后部安裝紫外線滅菌燈管所開槽也同樣留有手掌接觸燈管，將其取出的空間設(shè)計(jì)。前面開有長(zhǎng)方形孔，與筷槽貫通，筷子就從此處推出，供人們使用。下面設(shè)4個(gè)支撐角，避免底板使用時(shí)磨損和腐蝕。綜合所需3盞紫外線滅菌燈，其固定在底座上端，設(shè)立安裝燈座位置，并且能將紫外線照射到筷子盒里面。也就是說(shuō)紫外線（不可見(jiàn)光）照射不到的地方是不能起到殺菌消毒作用的。 廣泛應(yīng)用于醫(yī)院，空調(diào)系統(tǒng)，消毒柜，水處理設(shè)備，飲水機(jī)，污水處理廠，游泳池，食品飲料加工及包裝設(shè)備，食品廠，化妝品廠，奶制品廠，釀酒廠，飲料廠，面包房和冷藏室等領(lǐng)域。品牌：飛利浦品牌低壓汞燈。波長(zhǎng)低于200nm的紫外線可以空氣中將氧合成臭氧。 預(yù)熱型燈管：采用預(yù)熱電路，及相對(duì)緊湊和經(jīng)濟(jì)的鎮(zhèn)流器。由于這樣的結(jié)構(gòu)，冷陰極燈管不受開啟次數(shù)的影響，其使用壽命（20000小時(shí)）超過(guò)其他類型的燈管。Slimine系列殺菌燈管：為即開型燈管，其兩端采用線圈燈絲發(fā)熱。一般的紫外扥管都是使用的是石英來(lái)制成的，使用石英來(lái)制成的燈管往往具有很好的透明效果，熱膨脹的指數(shù)比較低，在給汞蒸氣壓燈進(jìn)行通電之后，在燈具的兩極就會(huì)產(chǎn)生一種電弧，隨著氣溫的升高，發(fā)出的光中就帶有明顯的紫外線。2）金屬鹵化物燈。 紫外線消毒燈，就是用紫外線殺滅包括細(xì)菌繁殖體、芽胞、分支桿菌、冠狀病毒、真菌、立克次體和衣原體等，凡被上述病毒污染的物體表面、水和空氣，均可采用紫外線消毒。第四章 紫外線消毒機(jī)構(gòu)設(shè)計(jì) 紫外線消毒原理 傳統(tǒng)的殺菌方法一般是利用加熱、加藥等手段，但這些處理方法所花時(shí)間長(zhǎng)，可能對(duì)處理對(duì)象產(chǎn)生不利的變化，對(duì)環(huán)境也會(huì)產(chǎn)生二次污染。可將筷子推出盒體20mm至40mm距離，以足夠方便人們?nèi)∮?。上部與連桿配合，直徑為4mm。用于與連桿連接。 滑動(dòng)推塊設(shè)計(jì)1. 思路：1）材料選擇耐磨； 2）設(shè)計(jì)時(shí)應(yīng)減少底面摩擦； 3）能準(zhǔn)確推出一雙筷子。47 第二章 筷子盒總體外形結(jié)構(gòu)設(shè)計(jì) 第三章 筷子盒取筷機(jī)構(gòu)設(shè)計(jì) 取筷方案設(shè)計(jì) 筷槽設(shè)計(jì)：1）筷槽設(shè)計(jì)成與底座一體結(jié)構(gòu)； 2）筷槽側(cè)面留有可供連接滑塊運(yùn)動(dòng)的開口； 3）筷槽長(zhǎng)寬高度需略大于筷子尺寸，能容納一雙筷子； 4）筷槽設(shè)計(jì)時(shí)應(yīng)該避免筷子重疊的情況；：圖 筷槽（單位：mm）3. 設(shè)計(jì)說(shuō)明： 筷槽設(shè)計(jì)長(zhǎng)270mm，比筷子盒大1
