Abstract

It is know that the dynamical analysis of a linkage is usually carried out by Lagrange-Euler equation in the theory of mechanic and mechanism. This method is allowed to take into account effects connected with the inertia, Coriolis, centrifugal and gravitational forces. All of listed factors are especially important due to the intensive working conditions of the most of modern machinery. Due to the wide functionality of linkages and their reliability and durability, they are widely used. However, the complex scheme of a multi-lever linkage makes accurate solution of dynamical problem difficult. Using the homogeneous transformation in Denavita-Hartenberg notation leads to the compact matrix form of the dynamical model. The algorithm and programs for the studied linkage are based on the proposed model. An actuator of a lifting machine is used as illustrative example.
