Optimal Design of Grooved Cam Profile Using Non-uniform Rational B-splines
MATEC Web of Conferences, 2017 In order to reduce the fatigue damage in grooved cam mechanisms, grooved cam profile was reconstructed with non-uniform rational B-splines (NURBS). Considering joint friction, dynamic model of grooved cam mechanisms was established and the contact stress
