The use of integrated Computer Aided Design/Engineering (CAD/CAE) software capable of analyzing mechanical devices in a single parametric environment is becoming an industrial standard. Potential advantages over traditional enduring multi-software design routines can be outlined into time/cost reduction and easier modeling procedures. To meet industrial requirements, the engineering education is constantly revising the courses programs to include the training of modern advanced virtual prototyping technologies. Within this scenario, the present work describes the CAD/CAE project-based learning (PjBL) activity developed at the University of Genova as a part of course named Design of Automatic Machines, taught at the second level degree in mechanical engineering. The PjBL activity provides a detailed overview of an integrated design environment (i.e. PTC Creo). The students, divided into small work groups, interactively gain experience with the tool via the solution of an industrial design problem, provided by an engineer from industry. The considered case study consists of an automatic pushing device implemented in a commercial machine. Starting from a sub-optimal solution, the students, supervised by the lecturers, solve a series of sequential design steps involving both motion and structural analysis. The paper describes each design phase and summarizes the numerical outputs. At last, the results of the PjBL activity are presented and commented by considering the opinions of all the parties involved.

“…The methods available at hand can roughly be classified into three categories, i.e. full order Finite Element Analysis (FEA) [4][5][6][7], lumped parameter methods [8][9][10][11] and semi-analytical methods [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Combining fundamental robotics with structural dynamics, it has been well recognized that the semi-analytical approach is particularly useful for the predesign stage thanks to its much lower computational cost compared to full order FE models.…”

“…Combining fundamental robotics with structural dynamics, it has been well recognized that the semi-analytical approach is particularly useful for the predesign stage thanks to its much lower computational cost compared to full order FE models. Along this track, several approaches have been proposed, known as Matrix Structure Analysis (MSA) [12][13][14][15][16], Virtual Joint Method (VJM) [17][18][19][20] and Component Mode Synthesis (CMS) [21][22][23][24]. In the MSA method, the flexible links are frequently treated as spatial beam elements.…”

“…The behavior predicted by the theoretical approach is then verified via the finite element analysis (FEA). An integrated simulation environment [34], in which a MATLAB parametric script guides the computer-aided design (CAD) geometry generations as well as the structural batch simulations, is used to automatically test several LET arrays for each DOF. The rest of the paper is organized as follows: Sec.…”

Lamina emergent torsion (LET) joints for use in origami-based applications enables folding of panels. Placing LET joints in series and parallel (formulating LET arrays) opens the design space to provide for tunable stiffness characteristics in other directions while maintaining the ability to fold. Analytical equations characterizing the elastic load–displacement for general serial–parallel formulations of LET arrays for three degrees-of-freedom are presented: rotation about the desired axis, in-plane rotation, and extension/compression. These equations enable the design of LET arrays for a variety of applications, including origami-based mechanisms. These general equations are verified using finite element analysis, and to show variability of the LET array design space, several verification plots over a range of parameters are provided.
