The purpose of this paper is to describe the concept, design, and analysis of a two-piece articulated piston for the Caterpillar 3500 diesel engine. Utilization of computer design and analysis enabled the piston to be optimized for structural capability, weight, and performance. Extensive analysis was performed on the steel upper structure. Models generated in two and three dimensions evaluated mechanical, thermal, and combined load cases. The result of this design and analysis is a piston that meets the engine’s objectives and provides additional value to the engine product.

VESPER (Visual Exploration of Similarity and PERformance) is a visual analytics system for exploring similarity metrics and performance metrics derived from computer-aided design (CAD) repositories. It consists of (1) a data processing module that allows analysts to input custom similarity metrics and performance metrics, (2) a visualization module that facilitates navigation of the design spaces through coordinated, interactive visualizations, and (3) a report generation module that allows analysts to export lifecycle data of selected repository items as well as the input metrics for further external validation. In this paper, we discuss the need, design rationale, and implementation details for VESPER. We then apply VESPER to (1) sustainability-focused exploration of parts, and (2) exploration of tool wear and surface roughness in machined parts.

Success of the design process hinges on efficient communication between the various functions involved. Traditionally this communication has been ‘paper based’ with information passing between sales, design, production and manufacture to describe the complete history of the product. This complex interaction between the functions depends on the availability at each stage of the most up-to-date and accurate information. The paper based system has many shortcomings in this respect particularly the inability of the designer to assess interactively the effect of any changes he may make on the cost, delivery, quality and performance of the product. The use of computer aided design as a central part of the computer aided engineering system allows a company greatly to improve communications during a project by giving the engineer a way of providing accurate information more quickly to each adjacent function while receiving feedback on the effectiveness and suitability of the product in a fraction of the time.

In this paper, a computer aided design of Vivaldi Antenna is developed which is used to study the effect of different parameters such as rate of opening of exponential slot and size of the radius of circular slot of the Vivaldi Antenna. The proposed design resulted in enhancement of gain and reduction in reflection losses. COMSOL Multi physics simulator is used to design the proposed Vivaldi antenna.

To assess the merit of using computer-aided design to model man in three dimensions, many potential problems and advantages must be considered. This paper addresses two related issues. First, it outlines several problems associated with obtaining information on the topic and second, it suggests several ways in which computer man-modelling is superior to traditional workplace design methods.
