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A flap vlave used in pumping station is a kind of hydraulic - operated automatic gate, which is similar to a hinged check vaive. because of their simple structure and reliability, being able to shorten the length of outlet passage and facilitate the starting of pumping system in comparison with siphonic vacuum - distroied cutoff scheme. so it is propitious to be used and save investment but at the same time, flap valves always show some disadvantage
因拍門簡單、可靠，與虹吸真空破壞截流閉鎖方式相比，可以縮短出水管道（流道）長度，並利於泵系統起動，與快速閘門相比，拍門也有諸多優點，閘門門體易關閉不到位或卡住不能活動，因為門槽和?塊較軸孔容易殘留異物，閘門門體克服滑動阻力不僅無機械增益，且阻力和動力不在一直線上，門體易傾斜而自鎖，而拍門的工作可靠性則遠高於快速閘門。
