摘要
无论控制油路的形式如何,就基于二次脉动油区的寻优原则,都存在着一个相对不变量△a_n/a_(nr),其中a_(nr)是调速油口面积a_n及在控制油路中与a_n 具有相同油流方向的油口面积决定。基于上述导出了一通用压力灵敏度函数(记为f)从而使得液压调速系统的二次脉动油压的寻优问题变得数学上简单,物理意义清析,并且更适于实际系统的特性研究。
No matter what form of the control oil path is,a relative
unchangable variable △anXanr exists certainly, where anr can be calcul
ated by the area of governor oil nozzle aa, and the area of oil nozzle in which oil flows in the same direction as aa based on the optimization
rules,a general sensitivity function (f) is derived, f=( pn/ an)am, so
that the problem of optimization of the secondary pulse oil pressure of hydraulic governor becomes mathematically simpler and physically clearer, and more suitable for study of characteristics of practical system.
