摘　　要：给出空间平面过约束和理论平面过约束的定义,分析了这两种过约束对机构误差的敏感特性,提出存在理论平面过约束机构的过约束分析方法,得到该类机构存在的过约束的数量和类型,从而为消除或减小该类机构过约束影响指明了方向。在此基础上,提出了该类机构的无过约束自调结构的的设计方法。The authors define spacial-plane-overconstraint and theoretical-plane-overconstraint, and analyze sensitivity of the two kindsof overconstraints to errors of mechanisms with theoretical-plane-overconstraint. Ananalysis method of the overconstraints of the mechanisms is present, and the overconstraint numbers and its characteristic is obtained. The analysis results are useful of designing for self-adjustable mechanisms without overconstraint. With this understanding,a synthesis method of self-adjusting structures without overconstraintis given.
