This paper presents a procedure for automated kinematic solution of constrained multibody systems such as complex mechanisms possessing low or high degree of complexity. The method utilizes the properties of constrained mechanisms which relate the kinematic characterestics of the individual links to those of the respective input link. The procedure developed is non iterative in nature and non graphical therefore can be conveniently programmed and executed on a minicomputer. An example illustrating the concepts of the method is presented. The acceleration analysis is executed on the basis of the auxiliary acceleration pattern corresponding to constant angular speed of the alternative input link. The results are compared with those obtained by using two different graphical methods.
