針對加熱彎管過程的受力和變形特點，採用三維梁單元、三維塑性直管單元、三維彈性曲管單元、三維殼單元與三維點對面接觸單元等5種不同的單元分別對管毛坯不同區域進行劃分，並對接觸單元採用柔體-柔體的處理方法，將溫度場作為體載荷處理，建立了符合實際的加熱彎管問題數值模擬力學模型：在此基礎上，應用商用軟體ansys對加熱彎管過程進行三維有限元模擬與研究，獲得了成形時推力、彎矩、支撐力大小及其變化趨勢。It shows with the increase of the amount of the mo in the si - mo infiltrant, the density of the infiltrated materials with the same performs increased, but the amount of the free carbon and pore also increased. it was the result of the capillary chocking - off caused by the separation of the mosj2 from the alloy infiltrant during the sintering process. after th thermal treatment at 2050, the amount of the free carbon and pore decreased. also. another cause for the unfully conversion of c into sic was the gas pressure. larger than the capillary force
實驗表明，對于同一坯體，隨著si - mo熔體中mo含量的增加，浸滲所得材料的密度隨之增加，但是，材料中的殘留c 、氣孔相的含量亦隨之增加。這是由於反應浸滲時，熔體中析出的mosi _ 2阻塞毛細管造成的。含殘留c 、氣孔相的材料進行高溫（ 2050 ）熱處理后，材料中殘留c 、氣孔相的含量大大減少。In the process of large - scale electromechanical equipment manufacturing, the degree of organization and management as well as measures of technique during the course of cutting stock, which do a great effect to produce cost and produce cycle
大型機電設備的生產製造過程中，零件毛坯下料生產的組織管理水平和技術手段，對設備的製造成本和生產周期有很大的影響。This paper discusses property of the pyrolytic graphite firstly, analyzes its application on the high power and supper high power ’ s electric tubes and points out the prevalence of the pyrolytic graphite used for grid ’ s material. then through experiment and discussion, this paper has obtained the scientific depositional technology of the pyrolytic graphite grid ’ s rough and accomplished this subject
本文首先對熱解石墨材料的性能進行了討論，並就其在大功率、超大功率電子管中的應用作了分析，指出了熱解石墨作為柵極材料的優越性能;然後通過試驗研究和討論，獲得了優化的石墨柵極毛坯沉積工藝，完成了課題目標。Jiangsu changshu siji sunshine solar energy co., ltd hereinafter referred to the company is an enterprise specializing in the production of solar water heaters and solar vacuum tubes. it has the most advanced automatic continuous high vacuum exhausting system and automatic vacuum coating production lines. the company uses the high - quality raw materials from tianxu group, with the most advanced production equipment, and hire professional and technical personnel involved in the production and management, which assure the good quality of products and professional technology. the company.
