Virtual prototyping for training in engineering design

Paladyn, Journal of Behavioral Robotics

Across numerous disciplines, virtual reality (VR) had been used to aid decision-making in training, design, and evaluation processes. Both the educational and industrial groups have contributed to a vast knowledge based on a variety of VR topics during the last two decades. VR has been expanded to industry in recent years, but the majority of its applications do not involve industrial robots. To study the application of VR technology in industrial design, it is better to combine the design activities with computer-integrated manufacturing system and bring new opportunities for the innovation of industrial design. Therefore, in this article, an application of industrial interactive design system based on VR technology in the education domain is explored. First, the function and scheme design of industrial robot assembly and adjustment system are designed, and the model is established. Finally, SolidWorks and 3DsMAX are selected as three-dimensional model development tools. Unity 3D i...

The growth of the need for visualization and manipulation of virtual prototypes and finished products, associated to possibilities of time, cost and staff economy that this technology provides, has increased the demand for Virtual Prototyping Laboratory (VPL). Thus, this study aimed to describe the possibilities raised by the development of a VPL as well as it aimed to describe the needs of hardware and software for its development. It is been observed that a VPL should include not only the virtual prototyping and virtual reality and also immersion and interactivity. In order to coupe with all these needs, the laboratory must have: High-resolution projectors and projecting capability, both in mono and in stereoscopy, with Infitec technology, on a screen suitable for this purpose; manager and graphics software capable of creating virtual environment and interactivity between the user and the environment; peripherals that enable the user immersion and interactivity.

What is graphic communication? Firstly, it is a very effective way of communication between the technical idea and the final solution of the problem in engineering. The process engineering design (design) begins with visualization, i.e., reviewing the problem and possible solutions. Then, sketching leads to the preparation of the initial idea. Next step is preparation of geometric models, which are used for a variety of engineering analysis and, finally, creating detailed drawings and/or 3D models, which are used for the production process. Visualization, sketching, modelling and preparation of technical documentation are ways in which engineers and technologists communicate in creating new products and structures in the modern technical world. Essentially, graphic communication, which is done via engineering drawings and models, is the clean, practical language with defined rules that need to be overcome if one wants to be successful in engineering design (any kind of design). When that language can overcome any approach to solving engineering problems. Ninety-two percent of the engineering design process is based on the graphic display. The remaining 8% is divided between the mathematical calculations and written and oral communication. Fifty percent of the projecting time a designer spends on are purely visual and graphic activities. We like precision in communication. Engineers use graphical tools, some of which are centuries old and are used day-today , while others are very new and conditioned by the rapid development of computer technology, such as Computer Aided Design (CAD) systems. From this chapter, users will be able to familiarize themselves with the above tools and principles of their use.

The three-dimensional geometric models used to present architectural and engineering work, show only the final form, which does not allow progress in constructions to be observed. But, the visual simulation of the construction process of a building need models which are able to produce dynamic changes to their geometry. This paper reports how techniques of geometric modelling and virtual reality were used to obtain models that could show their physical evolution over time and which would be able to simulate construction processes visually. Two types of work, concerning the construction of a cavity wall and a bridge, were developed as virtual models for educational purposes. These models make it possible to view the physical evolution of the work, to follow the planned construction sequence, to visualize details of the form of every component of each work and to support the study of the type and method of operation of the equipment necessary in the construction process. These models have been used to distinct advantage as educational aids in first-degree courses in Civil Engineering. The use of virtual reality techniques in the development of educational applications brings new perspectives to the teaching of subjects related to the field of construction.

VIRTUAL REALITY BASED CREATION OF CONCEPT MODEL DESIGNS FOR CAD SYSTEMS by Bilal Yehya Maiteh This work introduces a novel method to overcome most of the drawbacks in traditional methods for creating design models. The main innovation is the use of virtual tools to simulate the natural physical environment in which freeform design models are created by experienced designers. Namely, the model is created in a virtual environment by carving a workpiece with tools that simulate NC milling cutters. Algorithms have been developed to support the approach, in which the design model is created in a Virtual Reality (VR) environment and selection and manipulation of tools can be performed in the virtual space. The tool trajectories are generated by the designer's hand movements and they are obtained by recording the position and orientation of a hand mounted motion tracker. Swept volumes of virtual tools are generated from the geometry of the tool and its trajectories. Then Boolean operat...

The study aims to explore the usefulness of existing VR 3D modelling tools for use in mechanical engineering. Previous studies have investigated the use of VR 3D modelling tools in conceptual phases of the product development process. Our objective was to find out if VR tools are useful in creating advanced freeform CAD models that are part of the embodiment design phase in the context of mechanical design science. Two studies were conducted. In the preliminary study, the group of participants modelled a 3D part in a standard desktop CAD application, which provided information about the key characteristics that must be satisfied to obtain a solid model from a surface model. In the research study conducted with a focus group of participants, who were firstly trained in the use of VR, the same part was modelled using a VR headset. The results were analysed and the fulfilment of key characteristics in the use of VR was evaluated. It was found that using VR tools provides a fast way to ...

Design is an art and art is a design. Today, all industrial products are the result of a design process. Industrial design is a multidisciplinary field of study, which has a goal to create and produce new objects and it focuses on designing of products by using knowledge related with applied science as well as applied arts and various engineering disciplines. Academic programs related to industrial design focus on achieving the proper balance between practicality and aesthetic pleasure. Courses may include graphic and industrial design basics, manufacturing, modelling and visualization, environmental and human interaction in design. Computer aided design software are strongly emphasized. Students constantly observe, model and test their creations.

This paper describes an approach to implementing technology-assisted problem solving (TAPS) package using desktop virtual reality interface that brings together a 3-D model of an engineering mechanics problem in an interactive manner. It provides the user with a self-study environment in which to solve an engineering mechanics problem in mechanical engineering course. The package guides the user to solve a problem in a step-by-step approach and graphical environment. Integrating components such as 2-D, 3-D and stereoscopic images provides dynamic learning environment and guidance so that the learner can analyze the necessary actions to be taken in the virtual environment. Preliminary evaluation indicated that the TAPS package has great potential to aid teaching and thus provide an effective learning environment. http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=4568520&tag=1

The Department of Mechanical Engineering at San Diego State University recently began to redesign its introductory courses in mechanical engineering. The objectives of these newly designed courses are to incorporate the "learner as designer" strategy and engage students in real-world applications in order to positively impact student motivation and conceptual understanding of mechanical engineering concepts. To achieve these objectives, the courses are designed to use virtual reality as a tool that integrates the fundamental concepts of design, analysis, and manufacturing. The first implementation of one of these courses afforded an opportunity to study a particular type of "learner as designer" strategy-the "learner as instructional designer strategy." This paper describes the four courses and the impact of the "learner as instructional designer strategy" on students' conceptual understanding of and attitude towards mechanical engineering concepts.

3D solid modeling with CAD software is extensively used during design and development of products. There are several widely used CAD softwares available in the market. Training for students and individuals to use these CAD softwares are needed by both academia and industry. One of the primary media to provide training, including self-learning, is by using book and multimedia tutorials. These tutorials utilize text, snapshots, movies, etc. to facilitate learning of 3D modeling techniques for the CAD softwares. Usually the user reads the instructions and then tries to follow it using the software. Advancements in new multimedia technologies can provide higher level of interactions to facilitate the learning process. In addition, 3D web-based representations can increase understanding of creating 3D solid models and assembly processes for CAD software. In this paper we present an interactive training environment, where users are provided with interfaces in such a manner so that he/she can go though the steps of creating geometry in a simulated CAD environment. Multimedia tools are used to develop interactive 3D CAD tutorial in the simulated environment. In this paper the web-based interactive training environment has been developed for Pro/ENGINEER.
