Embodiment Construction
[0043] The present invention discloses a method for default correction of movable structure generalized coordinates based on cluster theory. The disclosed method will be further described below in conjunction with the accompanying drawings.
[0044] 1. Default correction of generalized coordinates of movable structure
[0045] Under a given geometric configuration, according to the constraint relationship between the nodes and members of the movable structure, the generalized displacement coordination equation of the overall structure can be established:
[0046] J·d=e (1)
[0047] Where J is the b×q-order generalized displacement coordination matrix, where b is the total number of members in the movable structure, q is the degree of freedom of motion of the nodes, and d in equation (1) is the q-dimensional structure generalized coordinate vector, and the equation (1) where e is the b-dimensional structure generalized deformation vector. In the analysis of the motion process, after ...
