在导水机械设计中,除了考虑结构上的要求外,如何得到合理的接力器行程与导叶开度间的关系曲线亦是设计工作的关键。在传统的设计中,通常是先给定一组导叶机构的参数,通过绘制导水机械的布置图来得到s=f(a_o)曲线。如果所得曲线线型不能满足技术要求,则需另选参数,重新绘图,反复如此,十分繁琐。现在由于计算机的广泛应用,S=f(a_o)曲线完全有必要,也有可能由计算机来绘制,但必须建立相应的数学模型。本文正是基于上述考虑
In the design of aqueduct, in addition to considering the structural requirements, how to get a reasonable relationship between the relay stroke and the guide vane opening curve is also the key to the design work. In the traditional design, usually given a set of guide vane mechanism parameters, by drawing the layout of hydraulic machinery to get s = f (a_o) curve. If the resulting curve line can not meet the technical requirements, you need to choose another parameter, redraw, repeated so, very cumbersome. Now due to the widespread use of computers, S = f (a_o) curve is completely necessary, it may be drawn by the computer, but the corresponding mathematical model must be established. This article is based on the above considerations
