In this study by the European Aluminium Association and FKA (Forschungsgesellschaft Kraftfahrwesen Aachen), a concept crash system for 40t trucks is developed based on the front end design used in the "APROSYS" study. The concept was built around European safety regulations in CAD software and simulated with an FE model using aluminum and steel. It was found that using an octagon shaped aluminum crush box would be the safest due to its characteristics of low weight, high energy absorption, and low technical complexity. Through additional testing it was also found if EU directive 96/53/EC could be modified to exclude cabin dimensions from its requirements, safer collisions for both parties would result.
Students practice creating rudimentary detail drawings. They learn how engineers communicate the technical information about their designs using the basic components of detail drawings. They practice creating their own drawings of a three-dimensional block and a special LEGO piece, and then make 3D sketches of an unknown object using only the information provided in its detail drawing.
Prologue: All too often current “CAD” text books concentrate too much on the software and not enough on the basic fundamental principles that are required to create a working industrial drawing. More and more college freshman enter the post-secondary arena knowing one or more cad software packages. A skilled instructor can rapidly get a group of students up to speed on whatever software package that is being used at that institution. However, over the last 25 years it has been my experience that many students only know the software…and not what to do with it. Now, this is not the fault of the technology education teachers in the secondary school system. They are most likely trained with a Charles Prosser philosophy that students leave high school with a set of skills grounded in meeting the needs of industry. However, since very few technology education teachers have actually spent any time in industry as a draftsman, designers, or engineers…the product they produce only knows “some” of what is required to be successful in the post-secondary arena. Make no mistake, this is not something done intentionally…it is simply the way “the American Education System” works. This document and the material contained within is being created to assist in both secondary and post-secondary educators who lack either the educational component of how to facilitate the required material…or more importantly, what that required material is.
This series of lessons will teach all of the key features in Tinkercad, a free, web-based 3D design platform. When you have finished the lessons you will have a comprehensive knowledge of how to design/draw in 3D. After that all you need is practice to improve your skills.

This course introduces computer-aided design (CAD) software. Students develop an understanding of the commands needed to produce a two-dimensional drawing. Topics include drawing setup, geometry creating, editing functions, layer techniques, dimensioning, model and paper space, title block creation, and plotting a completed drawing. Other related topics include multi-view drawings, selection and arrangement of orthographic views, section and auxiliary views, and isometric and oblique drawings. Students gain proficiency in the operation of a PC-based CAD system and a functional understanding of basic computer-aided drafting techniques.
Students practice human-centered design by imagining, designing and prototyping a product to improve classroom accessibility for the visually impaired. To begin, they wear low-vision simulation goggles (or blindfolds) and walk with canes to navigate through a classroom in order to experience what it feels like to be visually impaired. Student teams follow the steps of the engineering design process to formulate their ideas, draw them by hand and using free, online Tinkercad software, and then 3D-print (or construct with foam core board and hot glue) a 1:20-scale model of the classroom that includes the product idea and selected furniture items. Teams use a morphological chart and an evaluation matrix to quantitatively compare and evaluate possible design solutions, narrowing their ideas into one final solution to pursue. To conclude, teams make posters that summarize their projects.
This resource was developed by the Kent Career and Technical Center through seed funding from the CAAT and is a project-based curriculum that revolves around the construction of a working electric powered vehicle that will be entered into an Electrathon America race. This curriculum guides students through the design, build, and test process with their electric powered vehicle. Curriculum experiences include a combination of classroom, lab learning, on-site work experiences, and exposure to emerging green career pathways. The curriculum developed includes mathematics and science standards for Physics, P1-P4, with an emphasis on forces and motion, energy, and electricity for grades 9-12.
In this activity, students learn about creating a design directly from a CAD (computer-aided design) program. They will design a tower in CAD and manufacture the parts with a laser cutter. A competition determines the tower design with the best strength:weight ratio. Students also investigate basic structural truss concepts and stress concentrations. Partnership with a local college or manufacturing center is necessary for the completion of this project.
