Mobile app for the kinematic analysis of four bar mechanisms

Abstract

A mobile app for teaching the kinematics of four-bar mechanisms is presented, providing interactivity that allows the modification of input parameters and graphic adjustment to visualize the mechanism in the desired position for analysis. Velocities and accelerations of each link, as well as the angular positions provided, are the output values. The results of the velocities and accelerations in the centers of gravity of each link are also obtained, which are necessary for dynamic forces analysis. The app was developed so that engineering students have a reliable analysis tool available.
