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 。The disease in jaw surface will be drop the bite force ; the bite force in the patient who disease in temporal jaw joint descent obviously than normal person ; serious mistake in join deformity, the acute damage in the area arthritis can also drop the bite force evidently ; compare to normal children, wenneberg fund that the bite force lower and the duration of the biggest bite force shorter in the children who fall ill of the chronic arthritis ; the bite force also be used in appraise of the recovery condition in surgical operation 、 disorder in jaw arthritis and the serious bone offset in bite lopsided etc. some materials, it will be produce polarization phenomenon inside when suffered some force in certain direction, at the same time, it produce opposite electric charge in two of the surface ; and resume to the station of on - electrification when removed the outside force ; change the direction of the outside force, the polarity of the electric charge also be changed, this kind of phenomenon is called as “ piezoelectric effect ”
本文設計了石英晶體壓電傳感器，以它作為傳感元件把咬合力信號轉變成電信號;利用ts5860型準靜態電荷放大器把傳感器的電荷信號轉變成電壓信號;選用usb7822數據採集卡，編寫該數據採集卡的驅動程序，採集該電壓信號並送到計算機里;編寫labview程序對該信號進行處理，得出咬合力值和咬合力曲線，並把測量結果以電子表格的形式保存，以便做進一步的分析和研究。通過對該測量儀的靜態標定、動態標定、溫度漂移標定以及實際測量試驗，證實了本測量儀具有較高的靈敏度、受動態力和溫度變化的影響比較小、能實時地顯示咬合力曲線和較準確地顯示咬合力值，滿足了咬合力測量的要求。
