ADAMS will make some constraints invalid in the process of calculation automatically when redundant constraints exists in mechanism,then the joint reaction forces in any directions associated with redundant constraint equations will not be calculated.
机构存在冗余约束时,ADAMS会在计算时自动解除一些约束,从而使被解除约束的自由度上不会计算构件间的作用力。
This paper analyses several reasons for this,presents a method based on calculating the order of the Jacobi matrix to eliminate redundant constraints and degrees, then the constraint system can be solved based on sparse matrix decomposition.
本文分析了出现这种状况的几种原因 ,提出可以采用对雅可比矩阵进行下三角化求秩的方法来消除冗余约束和冗余自由度 ,然后再使用基于稀疏矩阵分解的方法进行求解。
Considering a set of inequality constraints gi (x)≤0 (i=1,2,…,m), if gi (x) is convex function, some sufficient and necessary conditions to distinguish gi(x)≤0 as a necessary or redundant constraint are given.
对于凸函数gi(x)(i=1,2,…,n)给出了约束gi(x)≤0是必要约束或多余约束的充要条件。
The characteristic of the instantaneous stable structure is that the structure s freedom degree is equal to zero,but still the structure remains a redundant constraint.
瞬变结构的特点是尽管自由度等于零,但仍有多余约束。
