摘要
发现采用基点约束法对机构进行计算机辅助分析时,在特殊情况下(如三点位于一直线上)无解或无精确解,建议增加第3类约束以得出满意的结果。运用自编的KACM通用程序对大量实例的计箅表明,此程序使用方便,通用性强,使基点约束法成为一种比较实用的计算机辅助分析方法。
No solution or no accurate solution is discovered on special state(e.g.,three points on a straight line)when the base point constraint method is used for the computer-aid- ed analysis of mechanisms.In order to obtain satisfactory results,it is suggested to add the third constraint.Many examples are calculated to use KACM general program.Computations show that the KACM program is not only convenient for use,but also can be available in many fields.The improved base point constraint method is a kind of practical computer-aided analysis method.
