摘要
过约束广泛存在于平面机构中 ,并导致了机械系统对制造、安装误差的敏感 ,对机械系统性能造成了一系列有害的影响。因此对过约束机构的研究越来越受到国内外机构学者的普遍重视 ,取得了一系列突破性的进展。详细分析了平面机构中过约束对机械系统性能的影响 ,介绍了目前国内外机构过约束的研究现状 。
Over-constraints that exist widely in planar mechanisms make mechanical system sensitive to errors out of manufacturing and assembly, bring on a series of infaust influences to behavior of mechanical system. This problem has been gained attention by domestic and overseas researchers, and some advances in field have been achieved. Oriented to the planar mechanisms, the paper analyzed the influences of over-constraints on behavior of mechanical systems, introduced research progress and some issues to be solved.
