Abstract

Mechanical Engineering Technology students take an Applied Kinematics Course in their third year at Purdue University North Central. Kinematics is the study of motion in different machine mechanisms. In this course, students learn techniques necessary to study the motions of machines and perform design concepts to optimize the motion of a machine arrangement. This paper discusses the current methods used and the incorporation of a new motion simulation software package. The topics of this course are the analysis and design of cams, gears, and linkages. Students analyze position, velocity, and acceleration of these different mechanisms. Some examples of the mechanisms analyzed are four bar linkage, slider crank linkage, scotch yoke, crank shaper mechanism, cam follower, spur gear train, and planetary gear train. Analytical and graphical are the two current methods used to analyze the mechanisms. The analytical method requires the derivation of the equations of motion to analyze the mechanism. These equations can be solved by hand or put into a spreadsheet to solve for multiple positions of the mechanism. This method is more cumbersome and does not allow the student to see the motion of the mechanism. The graphical method has the students use CAD software to analyze a mechanism. While students find this method easier, they can only evaluate one position at a time. Working Model has been introduced into the curriculum of the kinematics course. Working Model is a motion simulation package that allows students to build and analyze the motion of different mechanisms. Specific examples of the mechanisms analyzed are discussed in this paper.
