本文建立了一类般型空间五杆机构R R R S R优化数学模型,以及把一个中间运动参量作为浮动设计变量的、一般类型空间六杆机构R R R R C R优化数学模型。并用D F P变尺度法分别引进了数值计算。所阐明的观点及建立数学模型的方式方法,对各种特殊类型的空间五杆、六杆机构具有普遍意义。并可推延至空间7 R机构和空间多杆开式链机构中去。
In this paper, an optimization mathematical model of R R R S R for a general type of space five-bar mechanism and an R R R C R optimization mathematical model of a general type of space six-bar mechanism with an intermediate motion parameter as a floating design variable are established. The numerical calculation was introduced respectively with D F P variable-scale method. The viewpoints clarified and the ways and means of establishing mathematical models are of universal significance for all kinds of special five- and six-bar mechanisms. And can be extended to space 7 R agencies and space to open more chain mechanism to go.
