Abstract This paper presents an advisory conceptual design tool for mechanical transmission systems. Space consideration was taken into account during the design process. A prototype function tree was built in the form of knowledge-based system to transfer a designer’s idea into a set of mechanical components. An advisory expert system was also developed to help a designer in decision making. As an example, a packaging machine is designed using the developed system.

The Blended Wing Body (BWB) aircraft is based on the flying wing concept. For this aircraft the literature has reported performance improvements compared to conventional aircraft. However, most BWB studies have focused on large aircraft and it is not sure whether the gains are the same for smaller aircraft. The main objective of this work is to perform the conceptual design of a 200 passengers BWB and compare its performance against an equivalent conventional A320 aircraft in terms of payload and range. Moreover, an emphasis will be placed on obtaining a stable aircraft, with the analysis of static and dynamic stability. The design of BWB was carried out under the platform called Computerized Environment for Aircraft Synthesis and Integrated Optimization Methods (CEASIOM). This design platform, suitable for conventional aircraft design, has been modified and additional tools have been integrated in order to achieve the aerodynamic analysis, performance and stability of the BWB aircraft.

Designers and design researchers both agree that developing many feasible alternatives at the conceptual design stage is useful. In this paper we introduce generative configuration design (GCD) for conceptual design. We provide a partition of knowledge accessed during GCD and use the partitioned knowledge foundation to compare design tool architectures so that computational improvements can be made. We present an improved architecture for a GCD algorithm and implement it as a tool for office chair design. Subsequent examples show tradeoffs between computational load and design variety when applying constraints for behavior testing.

Mechanism and function formalization problem is touched in a novel task based conceptual mechanical design method. The general concept and a specific application of this method were reported in earlier publications. Direct dependence between the function and mechanism, identical synthesis tools for various stages of design and for various mechanical objects are the features making the suggested method advantageously different from existing concept design approaches. The core idea of suggested conceptual design method is the direct relation between challenged function and the mechanical entity which is in charge of implementing the requested function. The existing task based conceptual design methods are not satisfying the designer’s needs for scope of application, universality of design means, visualization and formalization of both mechanical and functional fields. Formalization of functions and mechanisms is an important design tool that will facilitate synthesis, analyzes, visualization and archiving (data base creating) processes of mechanical development. Further progress in unveiling the resources of the suggested design method is mostly based on development of formalization means for both categories of functions and mechanisms. The current study is unveiling newly developed function and mechanism description language that is helping to formalize both mechanical and functional categories facilitating their involvement in design process and making the description of a new product’s mechanical development easy and understandable. Function formalization in conjunction with mechanism formalization allows to formulate precisely the design task and concentrate the designer’s attention on solution of a single task strictly arranged in the hierarchical function tree of all involved tasks and functions.

Design Support Tool

National Maritime Research Institute of Japan (NMRI) has been developing the integrated design support tool, called “Harmonic Design Tool”, for evaluating economical / safe / environmental aspects of the offshore platform. We are also conducting the conceptual design of the offshore platforms for assessing the availability and accuracy of this design support tool. Seafloor massive sulphides (SMS) are high-grade hydrothermal deposits rich in copper, zinc and lead with a high gold and silver content. The Japanese Economic Exclusive Zone (EEZ) is well known to have high potential of SMS. Thus we decided the SMS mining as one of the most promising applications for the offshore platform technologies. Based on the published potential map of resources and the metocean database established in this project, we decided Izu-Bonin Arc as the target sea area and derived the design and operation conditions for the offshore mining platform. Then we proceeded to the basic concept such as the production rate and storage capacity, dynamic positioning system for station keeping and operation availability. This paper presents the review of the conceptual design of the offshore platform for SMS mining.
