Abstract:
A generalized expression of position errors of spatial linkage
mechanisms is derived from the loop equation. The parameters of motion
of the links are described by H-D matrix, and the differential matrices
take the forms of pre-multiplying and post-multiplying matrices. The
unknown variables of errors can be conveniently solved by an appropriate
selection of the first member and the end member of the mechanism, as
well as the premultiplying and post-multiplying differential matrices.
