This research presents analysis of a quick return linkage mechanism utilizing computational software Mathcad and Inventor. It is implemented as a class project to enhance Mechanical Engineering and Mechanical Engineering Technology students’ understanding of linkage mechanism in courses Dynamics and Machine Dynamics. The objectives of the project are to teach (1) kinematic and kinetic analysis of linkage mechanism (2) engineering math software Mathcad to solve the analytical model, (3) verifying the model by multibody dynamics simulation software Inventor. Loop closure equations based on complex number are first modeled and solved to find positions, velocities and accelerations of the linkage in Mathcad. Based on the kinematic solution, a kinetic analysis is carried out using distributed mass models in Mathcad as well as in Inventor simulation. The reactions and torques at the input link are found identical to those derived from simulation with negligible deviation. Integrating industry commonly used software Mathcad and Inventor in the project reduces the mathematical difficulties often encountered by engineering students. The course project assignment grade demonstrates that the use of these tools enhances the student’s understanding for linkage mechanism. The feedback from instructors shows the project make the course dynamic and engaging. The software-based project suits well for online teaching and learning.
