Abstract

It is required to calculate roots of a quartic equation for finding extremums of the transmission angle of an RSSR mechanism. If three roots of this equation are equal, the transmission angle will remain nearly constant within an interval. By normalizing the mechanism dimensions, the required conditions for these types of mechanisms are discussed.

Résumé

Il faut que calculer les racines d'une équation de degré quatre pour trouver des extrémes du angle de transmission d'un RSSR mécanisme. Si trois racines de cette équation sont égaux, l'angle de transmission reste presque constant dans un intervalle. En normalisant des dimensions du mécanisme, les conditions nécessaire pour ces types mécanismes sont discuté.

    The analysis and synthesis of spatial four-bar linkages are attractive and challenging problems. Several authors have made significant contributions in the area of rigid link RSSR mechanisms [1–11]. Mechanisms that gain some or all of their motion through the deflection of flexible members are classified as compliant mechanisms [12].
