計算結果實現了溫度及壓力對磨損模擬的影響，不確定因素對磨損壽命的影響，從而實現了高真感模擬的目標。To improve the transmitting characteristic and decrease the output work has a direct effect on the enhancement of the operating property and life - span of the operating mechanism of vacuum circuit breakes. based on the characteristics of polynomial rule of the cam movement, considering the pressure angle of cam device, an optimization model is established, with the coefficients of polynomial rule of cam movement as the optimizing variable, and the minimum output work of the mechanism as the object function. with the optimization tool box of matlab, the optimization process is conveniently completed and the perfect result of optimization design is obtained
改善真空斷路器操動機構的傳動運動特性，減小真空斷路器的操作輸出功，對提高真空斷路器的操作使用性能及壽命都具有直接的影響.利用凸輪機構的多項式運動規律的特點，以凸輪多項式運動規律的多項式系數為優化變量，以斷路器操動機構最小的輸出功為目標函數，考慮操動機構合分閘時凸輪機構傳動壓力角的情況，建立了彈簧操動機構中凸輪機構的優化數學模型，並利用matlab語言的優化工具箱方便地實現了優化過程，得到了較理想的優化設計結果The traditional molecular pump with popular bearing can not meet the challenge of semiconductor manufacturing because of the vibration, short life, unpure vacuum and so on. so it is very important to design the magnetic bearing and power amplifier for molecular pump
本課題研究的目的是，解決傳統軸承型分子泵應用在半導體製造行業時出現轉速低、壽命短、真空不潔凈等問題，設計分子泵的磁懸浮軸承結構和功率放大器，對實現分子泵在半導體工業中的良好應用有著重要的意義。Then because the real operation temperature of the tube is the critical factor for predicting the tube lifetime, we heat some unused tubes in the lab. then we measuer the rigidity of them and find the relationship between the hardness and heat - intensity parameter
其次，由於管件的真實使用溫度是預測其壽命的關鍵因素，因此，本文通過對未用管材按照幾種不同的加熱規范在實驗室進行模擬加熱，測定其加熱后的硬度，找出顯微硬度與熱強參數的關系。分享友人
