Abstract

QUICK-RETURN MECHANISM REVISITEDAbstractIn this paper, the teaching and learning experiences of the author with two summer interns at oneof the educational institutions in India is presented. These are the senior mechanical engineeringstudents from two different engineering colleges in India who spent nearly two months at theuniversity where the author spent a 3-month sabbatical as a visiting faculty. Although these twostudents took the “Theory of Machines” course at their college, a complete understanding ofkinematic and dynamic analyses of mechanisms such as a quick-return linkage were not realizedby both parties. The students were taught the basics of loop-closure equations pertaining to thekinematic and dynamic analysis of an example quick-return mechanism and were asked todevelop an Excel based program to perform calculations and plot the various characteristics suchas variation of quick return ratio as a function of the critical link lengths, kinematic and dynamiccharacteristics of the linkage, and the results of an effort to partially balance the system. Thestudents were also asked to model the linkage using the motion simulation application that iscommonly available in any CAE tool such as Catia, UG-NX, NX I-DEAS or SolidWorks.Finally, the students used the available laboratory experimental apparatus to verify some of thetheoretical calculations. The performance metric is a final report that included the learningoutcomes and recommendations for further work. It is believed that the developed Excel programcan be easily used as it is or adapted by other faculty teaching the Kinematics course.
