Prototype design education for cinematic learning mechanisms:aplications to the mechanisms to conrod crank with runner

Abstract

The present investigation is related to the design, construction and manufacture of a didactic prototype of a rod-crank mechanism with a slider that allows to visualize and understand fundamental principles of its operation as well as its kinematics. Relating the traditional method of kinematics called Velocity Polygon with CAD design, additive manufacturing and automatic control. The objective of this project is to generate a controllable didactic prototype that allows us to visualize and understand fundamental concepts of the mechanism's operation as well as real-time information on the kinematics of its joints (nodes). Through the database generated by a instrumentation created in LabVIEW, movement simulation of the cad design and the velocity polygon graphic method, it was found that the speed of the sliding node coincides in the three methods, thus achieving a device that allows us to offer a more practical approach, in the development of technical skills, resolution of mechanism problems in undergraduate students in mechatronics, mechanics and Industrial
