Laboratory work is an important element in engineering training, which should correspond to up-to-date tendencies in computer-based technologies in design, production, maintenance and preserving mechanisms. Computer-based laboratory work consists of 16 assignments. Seven assignments are carried out on laboratory stands, the remainder are provided on PC, using programs like “Visual Structure Editor”, “DYNAMO”, “APM Win Machine”. The system Visual Structure Editor (VSE) is designed by specialists of “Machine Mechanics and Computer-Aided Design” department, of the Maritime State University named after adm.G.I.NEVELSKOY, Vladivostok, under the direction of prof. Valentina V. Kuzlyakina. The system APM (Automated Projecting of Mechanism) is designed by the research-and-production centre “APM” under the direction of prof.V.Shelofast, from the city of Korolyov, Moscow area. These systems are multifunctional. They allow project different mechanical systems at the stage of structural and parametrical synthesis, carry out strength calculations and design elements of machines and mechanisms. They are good in operation. Teachers and students easily master the systems. Laboratory works with computer support allow students to pass from a concrete object to modeling on a PC, and to solve complex engineering tasks during the education process.

Significant Attention

Modeling the human arm and calculation of the human arm reach are important for designing workspaces. An appropriate workspace design would reduce musculoskeletal disorders and wrist injuries in repetitive tasks. Among different human arm workspace designs and reach calculations, computer-based methods have recently attracted significant attention. This is because conventional experimental methods do not provide sufficient flexibility for interactive design modifications and integration of different aspects for workspace design. Despite advances in computer-aided design, many computer-based methods still rely on mock-ups and experimental set-ups. In this work, a computer-aided method is investigated for predicting the human arm reach. The kinematic modeling convention of Denavit-Hertenberg is adopted for formulating the reach. Simulation results are provided to demonstrate the effectiveness of the method. The methodology enables visualization of the reach volume of the human arm and could be easily adjusted for different human operators.

The current stage of development of learning management systems is associated with use of opportunities provided by global computer networks and technological standards developed in distance education. It offers structuring of educational material in electronic course and approach to navigation modeling, which are consistent with international specifications of e-learning SCORM and IMS, adding to them specific adaptive algorithms for navigating through training courses based on use of the model of integral evaluation of student's knowledge. In this chapter professor Irina Sidorkina (Volga State University of Technology) and professor Vardan Mkrttchian (HHH University) using the results previously obtained for the implementation of Computer - Aided Design as Carrier of Set Development Changes System in E-Course Engineering. Dr. Alexey Rybakov (Omega-R Inc.) was a designing a software on the subject of this chapter.

Aided Design

The modification of the caisson in a dry dock is in many ways more difficult than conventional ship modifications. This is because of the accuracy required, location of the measurements, and the size of the structure. The development of computer-based multi-headed electronic theodolite systems made it possible to extract accurate data on large structures. These data were formatted so they could be input directly into a computer-aided design system. The multi-headed electronic theodolite system was used to transfer new design information directly to the structure. The caisson structure was modified and moved safely into position with the aid of a water castor system for final assembly. Final dimension checks verified the accuracy of the system.

The use in design, of knowledge and understanding of human thermal comfort, heat stress and cold stress, is often complex and time consuming. A computer based system (IBM-PC) was developed to allow human factors practitioners to assess and manipulate knowledge, data and simulations of human response to thermal environments, thus allowing computer aided design. A description of the system, its design and development and examples of its use are provided. The role of such systems in design and assessment should be considered by human factors practitioners.

Automated Line

This paper presents the main CAD –computer aided design – elements of an automatised assembly/test line, destined for work posts for the assembly/testing of the subsystem-carcass, in agreement with Compa SA Sibiu. The carcass is part of the turbo-compressor assembly (compressor + turbine) of a testing equipment. The analyzed line contains 7 work posts, with direct application to the assembly/test disc type parts but it can be generalized to the serving, to the purpose of testing, of many such posts in a automatised assembly line and carcass checking. Because carcass with lacking or inconsistent processing can end up on the assembly line, it has been decided to design and produce an automated line, so these things should not happen, because these part son an automated assembly line can cause the stopping of automated flux until the faulty part is being replaced.

Attempts to include Computer-Aided Design and Computer-Assisted Learning facilities in a substantial way into undergraduate teaching lead inevitably to a consideration of appropriate (efficient) methods of instruction. A method based on syndication of tasks, used at Ulster Polytechnic, is described. The method has been found particularly useful in teaching System Dynamics and Control.
