%0 Journal Article %T KINEMATICS OF A MECHANISM WITH STOPPINGS, BASED ON A HYPOCYCLOID WITH 6 BRANCHES %A Liliana LUCA %A Iulian POPESCU %J Revista Fiabilitate si Durabilitate %D 2010 %I Academica Brancusi %X They are studied the positions, velocities and accelerations of a mechanism based on planetary gear and a RRP dyad. The mechanism ensures the plunger stop on a certain subinterval of the cycle, although the leading element is rotating. Because of the approximation of the hypocycloid shortened arc with six branches, by a circle arc, errors occur. %K planetary mechanism %K stoppings %K hypocycloid %U http://www.utgjiu.ro/rev_mec/mecanica/pdf/2010-02/8_Luca%20Liliana.pdf
