Enhancing learning of kinematics and fatigue failure theories using CAD modeler

Abstract

Mechanical Engineering is the branch of engineering that specializes in the design, production, and uses of machines. The physics of mechanics is widely used in mechanical engineering. Educators make continuous improvements in providing quality education to ensure that mechanical engineering students understand important concepts and develop skills to apply them in practice upon graduation. Engineering software tools are enabling educators to develop innovative new techniques that enhance the learning of many mechanical engineering topics. This paper discusses the use of SolidWorks CAD modeler to develop learning tools that support the understanding of concepts of mechanical engineering topics such as kinematic synthesis, kinematic analysis, and fatigue failure theories. Specifically, three-position synthesis with specified moving pivots of a four-bar mechanism, symmetrical linkage with synthesis of one of its cognates, and 3D fatigue diagram that extends the traditional 2D fatigue diagrams are described. Effective use of sketch, drawing, and solid model tools with solid modeler are discussed. The productivity of CAD tools in significantly enhancing learning is recognized through the discussion.
