QUINTERO, Héctor; CALLE, Gabriel; DIAZ, Alexander  and  HENAO, Edison. A novel graphical and analytical method for thekinematic analysis of fourth class Assur groups. Rev.fac.ing.univ. Antioquia [online]. 2011, n.60, pp.81-91. ISSN 0120-6230.

A method for the kinematic analysis of a fourth class Assur group, using a combination of graphical and analytical methods, is presented in this paper. The solution is obtained through a method in which two special Assur points are used. A mechanism of 1 DOF with a fourth class group is considered as an example to develop the proposed method. The results of this method are in agreement with the results obtained by a dynamic simulation program. Since there are no solutions for fourth class structural groups in the literature, this method allows developing a complete modular procedure for the kinematic analysis of mechanisms, with the methodological advantages that this type of solution offers.

Keywords : Kinematic analysis; fourth class Assur group; structural analysis.
