文摘The path generated by a linkage in general deviates from the specified path. In this paper,the deviation is analyzed based upon the reliability concept and a reliability-based optimal synthesisprocedure is presented for path generating mechanisms. Both structural and mechanical errors areincorporated in the objective function. A four-bar path generating mechanism is considered fornumerical illustration and the results are compared with those obtained by deterministic procedure.As expected, the presented approach is superior to the deterministic procedure.
