摘要:

AbstractCircuit simulators play an important role in circuit design. However, their sintaxis is usually not friendly for students having their first exposure to this technology, causing reluctance toward the use of these kind of software aids. This fact was a driving force for the authors to propose a system called RECIA, by means of which the student could have access to a circuit simulator without having any knowledge about the sintaxis of it. In addition, input/output to the system is in a graphic environment. In this way, the student only has to specify as input the schematic diagram of his/her circuit and obtain as the output plots of the desired voltages and currents. The simulator chosen in this work can be anyone belonging to the family of SPICE simulators. RECIA is a shareware package available on request from the authors. One of the most important aspects of RECIA is that it does not need previous extensive training to be readily used by students and yet, a simulation run can be done in the very first minutes of use. This is an advantage over other simulators with schematic capture which require some time to learn the sintaxis.

摘要:

AbstractSome facets of our robotics research require the simulation of a mobile vehicle to study navigation and control problems. We have developed a 3‐D animated graphical simulation of the movement of a wheeled vehicle under interactive control of the computer user. The article describes the mathematical formulation of the dynamics and the programming procedure to display the vehicle movement. Besides the possible use of our program for robotics education, the aspects covered by this article could be useful for motivating mechanics and graphics programmin

摘要:

AbstractThe CHprogramming environment is an open system. Users can enhance the system through its various user interfaces. CHis specially designed for applications in mechanical systems engineering, although it is applicable to many other disciplines as well. CHhas been successfully used as a teaching and learning tool for an undergraduate course, Computer‐Aided Mechanism Design, at the University of California, Davis in Fall 1993. In this article we will present the CHprogramming environment and programming features developed for teaching and student learning. We will describe how a teaching toolbox is developed and used for teaching mechanism design. Source codes in the teaching toolbox are available to students so that they can study the software implementation of algorithms and modify the codes to solve similar problems. Although the developed teaching toolbox is specific for instruction on mechanism design, the CHprogramming environment and ideas presented in this article are general, and they are applicable to instructional improvement for a wide range of subjects in engineerin

摘要:

AbstractIn this article a tutoring system is presented to act as a platform for research students to study data acquisition. In addition, it could be used to program and operate an existing hardware setup. The hardware consists of a number of sensors attached to a programmable data logger, and collected data are transferred to a PC via a pair of short‐haul modems. The tutor exhibits the flexibility required to meet different needs of research students in information technology and environment‐related studies. In addition, it has the capability to act as a user‐friendly interface able to operate complex s

摘要:

AbstractThis article describes a program based on the boundary element analysis (BEA) method that has been designed to bring continuum stress analysis to the academic environment. Interactive Stress Analysis is a unique interactive graphic computer program designed for use in undergraduate engineering education that allows students and instructors to pose continuum stress analysis problems naturally and examine their answers. Currently, the program is in a prototypical, yet demonstrable form. First deployment in a strength of materials course is planned for Fall 1994. With additional support we propose to investigate the incorporation of multimedia technology and an enhanced version of Interactive Stress Analysis in a prototype lecture series on strength of materials with potential widespread distribution. In the sections that follow, the capabilities, techniques employed, and overall rationale and philosophy associated with the development of this program are described.

摘要:

AbstractThe Finite Element Analysis (FEA) method has been in practical use in industry for the last 25 or so years. Training seminars to teach FEA concept to practicing engineers using the various codes have existed for nearly the same time period. A particular drawback to the general methods used by the commercial FEA industry presupposes that an experienced engineer is looking for a design analysis tool. On the other hand, FEA now reaches a universal audience and its techniques are beginning to be taught in undergraduate engineering curricula. The problem in the academic setting is closing the loop between theory and practical use of FEA codes. For starters, schools may not have access to commercial codes, and if they do, faculty may not be well versed in the use of a particular code. Schools not having commercial codes are limited to using software that often come with textbooks. Even when commercial codes are available, there is a distinct lack of appropriate training aids that integrate the theory and practice for inexperienced practitioners. This article discusses how FEA is being taught at The University of Alabama (UA) in the undergraduate Mechanical Engineering department to circumvent this problem. A simple example will demonstrate the theory‐to‐practice connection using a commercially available c

摘要:

AbstractSpecially developed computer software for a three‐phase induction motor simulation for an undergraduate course is presented. The computation time of the simulation method used is reasonably short: about 29% of the CPU time required by the ordinary fifth‐order model. Using the software tools developed, students can effectively perform analysis of induction motors at various modes of operation. The software is viewed on the color display of a personal computer, and each part of the program may be activated by means of a user‐friendly graphics e
