文摘:從理論上分析了芯棒倒錐角和芯棒長度對內螺旋凸筋形狀畸變的抑制和消除作用，提出了採用倒錐形等螺距芯棒拉拔內螺紋管時芯棒幾何參數的設計方法。The results show that for all of parameters considered in this study, the friction factor of fin surface without vgs is smaller than that for fin surface with vgs ; the increase of friction factor under low reynolds number is large, but with reynolds number increasing, the increase of friction factor is quite small
實驗結果表明：在不同管間距、板間距時，板芯裝渦產生器阻力系數均比光板板芯的阻力系數大，並且在低雷諾數時的增幅比較大，隨著雷諾數的提高，阻力系數逐漸降低並趨于平緩，且阻力系數增幅大大減少。The author analyzes the structure characteristics of tube splice of a vacuum cleaner, specializes several methods to solve arc core pulling and lays stress on a new structure design for a great angle and a long distance side arc core pulling driven
摘要分析了吸塵器彎管連接頭的結構特點，著重闡述了應用於本模具中的一種新穎的專用來解決大角度，長距離抽芯的連桿機構的工作原理。
