In this paper, 5R-C mechanism is taken as an example to carry out the error analysis and synthesis of spatial six-link mechanisms and to use multi-criteria optimum synthesis for considering mechanical errors and manufacturing costs. In order to save computation time, various identity conditions of geometrical closure are used to derive a certain number of necessary-equations which contain less unwanted motion variables. As a result, sets of linear equations are obtained to solve for partial derivatives necessary...

In this paper, 5R-C mechanism is taken as an example to carry out the error analysis and synthesis of spatial six-link mechanisms and to use multi-criteria optimum synthesis for considering mechanical errors and manufacturing costs. In order to save computation time, various identity conditions of geometrical closure are used to derive a certain number of necessary-equations which contain less unwanted motion variables. As a result, sets of linear equations are obtained to solve for partial derivatives necessary to the error analysis of spatial multi-link mechanisms. Clearance vectors at real kinematic pairs may be simply converted into extra errors of structural parameters with satisfactory approximation. Further more, by the stochastic model set up in the paper, clearance vectors are also analysed satisfactorily to obtain statistical amounts having practical effects. On the basis of error analysis, the general applicable multi-criteria optimum programs for cousidering manufacturing tolerances and clearances of spatial mechanisms have been developed.

本文主要以5R—C机构(R表示转动副,C表示圆柱副)为例,进行了空间六杆机构的误差分析与多目标优化综合。为便于上机计算,对于多杆空间机构误差分析中所用的偏导数,文中利用机构封闭性的各种等同条件,通过含有较少中间运动变量的线性方程组求得。对于各种常见运动副中的间隙误差矢量采取了折算为有关结构参数的附加量的方法,通过所建立的随机模型进行了统计分析以得到实际影响大的统计量。在误差分析的基础上,本文进一步对空间连杆机构提出了通用性较强并且考虑公差和间隙的多目标优化程序。

In this paper, a mathematical model for optimal synthesis of general typal with spatial five-link RRRSR mechanism and a mathematical model for optimal synthesis of typal with spatial six-link RRRRCR mechanism are presented. New kinematic constraints of RRRSR mechanism and RRRRCR mech anism are introduced here. An intermediate kinematic parameter in RRRRCR mechanism is made into the floating design which is variable in the optimigational procedure. The optimal syntheses for these mech anism for function generation...

The optimal syntheses for these mech anism for function generation are completed by means of the DFP rescaling technigue.
