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。This paper first conducts the research to the steel wire roller conveyer ball bearing rolling body and the steel wire roller conveyer spot contact question, gives the main geometry parameter of the zone of contact by the hertz contact theory, stress extreme value as well as contact body elasticity approach quantity formula, and acts according to the practical application to carry on the simplification, calculates the main parameter of the bearing zone
本論文首先對鋼絲滾道球軸承滾動體與鋼絲滾道的點接觸問題進行研究，由hertz接觸理論給出接觸區的主要幾何參數，應力極值以及接觸體彈性趨近量的計算公式，並根據實際應用進行簡化，計算出課題所研究軸承接觸區的主要參數。The results indicated that the dimension, shape and purity of base material could meet the functional demand of solid lubricant ; the thermal decomposition temperature of ptfe resin exceeds 400 c, but organic and inorganic packing filler added in ptfe made the water absorption rate of composite material increased, melting temperature and decomposition temperature decreased, in the meanwhile oxidative decomposition reaction was accompanied ; polar groups such as c = o, c - o - c and so on in the carbon fiber surface is advantageous to increase compatibility with other components and interlayer shearing strength ; uniform design experimental method could help to find the relationship between formula and frictional property by relatively small tests. the developing trend of each formula ' s friction coefficient could be showed by fitting curve ; the friction coefficient with no copper powder or graphite in formula was relatively big. this fact showed that copper powder and graphite should be used cooperatively ; it was found that when the ratio of copper powder to graphite by weight is 15 : 60, 30 : 30 - 40 and 60 : 15 - 30 respectively, the friction coefficient was relatively small. the degree of crystallinity of pure ptfe reached maximum by air cooling and the abrasion loss also reached maximum among three ones ; at the same time, the abrasion loss of solid lubricant sample was also the biggest among three ones ; when solid lubricant matched with 45 # steel axle or gcrl5 steel axle, lubricant transfer film could be formed on metal surface, thus direct contact between the surface of metal friction pair rings was reduced. their working life was elongated extremely ; there was mainly much graphite, a little ptff, moo3, feso4, cus and so on in lubricant transfer film
試驗結果表明：所選原料的尺寸、形狀及純度可滿足固體潤滑劑的性能要求；聚四氟乙烯樹脂熱分解溫度超過400 ，但在ptfe中加入無機填料會使復合材料吸水率提高，熔融溫度及分解溫度降低，且伴有氧化分解反應；碳纖維表面含有c = o及c - o - c等極性基團，有利於提高其與其它組分的相容性，提高層間剪切強度；均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系，擬合曲線基本能表示各配方的摩擦系數發展趨勢；配方中不加銅粉或不加石墨，其摩擦系數均較高，說明銅粉和石墨應該配合使用；當銅粉15份、石墨60份時，銅粉30份、石墨30 - 40份時，銅粉60 、石墨15 - 30份時，摩擦系數均具有較低值；純聚四氟乙烯樹脂在空氣冷卻時結晶度最大，磨損量也是三者中最大的；同時，固體潤滑劑試樣在空氣冷卻時的磨損量也是三者中最大的：不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副，在金屬表面均可形成潤滑轉移膜，從而減少金屬摩擦副表面間的直接接觸，大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。With the development of computer, power electronic, sensor technology, intelligent electric apparatus is the evolution direction of electric apparatus in 21 century. existing contactor testing technology ca n ' t meet the requirement of theory research and production development. based on analyzing the present situation and trend of contactor testing technology, both of contactor testing technology and performance evaluation method, are researched in this paper
