Abstract: A reliability-based analysis approach to mechanical error in
path generating linkages is presented. The reliability index is
taken as a measure for the deviation of the actual path of a
coupler point from the desired one. A reliability-based synthesis
procedure of the mechanical error for path generating linkages
to allocate tolerances and tolerances is developed. A four-bar
path generating mechanism is considered for numerical
illustration.
Key words: Four-bar
