  1. We also studied the dynamic characteristics of cf / cu ( c ) - cu composites, the results show that, by the method of graphite is coated with copper, the coefficient of friction and the wear rates remarkably decreased. with the increase of the copper coated carbon fiber content, the wear rates of cf / cu ( c ) - cu composites is notably decreased, while the coefficient of friction is increased. with the increase of electric current density, the wear rate of cf / cu ( c ) - cu composites is increased

    研究發現,碳纖維鍍銅石墨-銅復合材料的電摩擦磨損性能與碳纖維含量存在一最佳值,當碳纖維含量為0 . 6時,其電摩擦磨損性能最好;對于不同電流密度下的電磨損性能的比較可以發現,通電磨損時的電摩擦系數要小於機械磨損時的摩擦系數,碳纖維鍍銅石墨-銅復合材料的電摩擦系數隨電流密度增大先減小而後增大,在電流密度為15a cm ~ 2時達到最小值;通電磨損量要遠大於機械磨損量,且隨著電流密度增大,磨損量增加。

In the third chapter, the mathematical models of project system have been established, and simulation has been done on the simulink enviroment of matlab software kits. the simulation focus on the effects of main parameters on the dynamic characteristics of speed control system, and the main parameters include viscosity damp coefficient and friction torque of electrical motor shaft, internal leakage coefficient of pump / motor of hydraulic circuits, gas volume of pressure accumulator, viscosity damp coefficient of cylinder piston and different running building floors, etc. at last, theoretical research effects of the flow and pressure pulsation of pump / motor on car speed and oil volume leakage theory are discussed. the fourth chapter of this thesis concerns the research on the key items about hydraulic power control system according to the ens 1 - 2 and other hydraulic elevator standards

    論文第三章針對組成系統的各個模塊進行了機理建模,並且通過matlab軟體中的simulink圖形化模擬環境進行了本課題系統的模擬研究,主要針對影響系統特性的主要參數變化,動態分析系統的輸出特性,在上下行工況中,分析了電機軸系粘性阻尼系數、軸系摩擦力矩、主迴路蓄能器迴路液壓泵馬達內泄漏系數、蓄能器氣體容積、液壓缸柱塞粘性阻尼摩擦系數以及不同運行樓層工況等參數對系統特性的影響;最後對軸向柱塞泵馬達的流量壓力脈動對電梯轎廂速度的影響和蓄能器內油液體積損失機理進行了理論研究。
  6. Based on the analysis, we gave an example to study the dynamic contact with friction of the intermittent joint, and got some essential rules : the friction coefficient could n ' t influence the distributing of dynamic stress on the contact surface, and the roading rates affected evidently on the dynamic characteristic on the contact surface. in the last part, this paper made respectively use of the time - history method and the response spectrum method to analyze the dynamic response of the rock slope on baise hydraulic power plant, and got the coincident resultant. simultaneously, the contact theory was applied to study the stability of the intermittent joints

    基於上述的接觸理論和接觸分析結果,本文在最後一部分中分別利用動力時程法和反應譜法對百色水電站尾水渠的巖質邊坡進行動力響應分析,兩者計算方法得出比較一致的結果,同時採用動力摩擦接觸理論重點分析了斷層對于邊坡的穩定影響,認為斷層的存在會使得巖坡的穩定性降低,在地震等動力荷載的作用下對于斷層將發生張開、閉合和錯動現象,尤其是動力荷載和其他荷載如滲流力等的耦合作用將會對斷層產生極為不利的後果,進而影響巖坡的整體動力穩定,應該要引起足夠的重視。
