Tolerance analysis and synthesis of cam-modulated linkages

摘要: Abstract Cam-modulated linkages that can achieve superior kinematic performance as compared with pure have been widely applied in a variety of automation machinery. The tolerance analysis and synthesis are thus quite essential the design manufacture precision cam-modulated linkages. This paper presents comprehensive systematic mathematical tools for dealing Based on concept equivalent linkage derived correlation between radial-dimension errors normal-direction cam profile, sensitivity method is introduced analyzing tolerances linkages, whose output error equations be through an analytical means. Then, by incorporating manufacturing assembly (DFMA), optimization model synthesizing developed. objective this to maximize manufacturability assembility while maintaining acceptable accuracy its motion. A practical case study type pick-and-place device then performed illustrate presented methods. It shows helpful
