Modeling and data exchange in a concurrent and collaborative design environment for electric ships

Abstract

Recent advances in the sensor and weapons systems being installed on US Navy ships and the electrification required to power them are now forcing the engineering community to re-evaluate the effectiveness of the tools and processes now in use. At the same time, over the last decade there have been significant changes in the way that software is architected and developed. User expectations for software tools have also radically changed. Newly minted engineers have grown to expect that any needed information can be easily found and that interactions with peers can happen seamlessly, allowing for ideas to freely flow. Now, more than at any other time, the complexity of the design of modern ships calls for new design tools and methods that permit, early in the design process, interactions and the exchange of information and ideas between all major disciplines including electrical, mechanical, thermal, control engineers, and the traditional naval architecture and marine engineering teams. The Electric Ship Research and Development Consortium (ESRDC) has developed a collaborative design environment called S3D (Smart Ship SystemDesign) with the goal of reforming the way in which engineers collaborate, model, design, and simulate complex systems, bringing together, as never before, the various disciplines involved in the ship design process. This paper will focus on the modeling and data exchange concerns that have typically represented major obstacles in the implementation of a collaborative design environment and the approaches taken by ESRDC and others to resolve these problems.

Derivation of Power System Module Metamodels for Early Shipboard Design Explorations

“…Regarding part c of initialization, (18) and (19) formulated by [40] outputs passing and failing values for less-than-or-equal-to and greater-than-or-equal-to constraints, respectively: (18) gte (x, (19) If the sum of the constraint outputs is less than the total number of constraints -that is, if a specific configuration that does not pass all of the constraints -the inductor model automatically receives a poor fitness value.…”

“…The Navy has also invested heavily in the PEBB Concept for building up ship power conversion systems [2], [17], [18]. The Navy has developed Smart Ship System Design (S3D) concurrent engineering environment to support early concept explorations on ship system designs from electrical, mechanical, thermal and layout standpoints [19], [12]. The author of this thesis have proposed a meta-heuristic modeling approach that can be used to derive physics-based scaling laws [15].…”

Modelagem e análise de sistemas de propulsão naval: abordagem baseada em sistemas híbridos.

“…), além de apresentar uma grande interdependência entre elas. Por este motivo, estes projetos são tratados como sendo de grande complexidade (LANGLAND et al, 2015) e ao envolverem uma grande gama de disciplinas, a análise dos subsistemas e seus componentes torna-se uma tarefa relativamente complicada ao requerer intrinsecamente que os projetistas detenham tantos saberes distintos. Logo, torna-se imperativo a adoção de uma metodologia de projeto adequada para que a solução a ser desenvolvida seja a melhor, frente aos requisitos a serem considerados.…”

“…Alternativamente, a metodologia descrita neste trabalho pode ser usada dentro da visão de Projeto baseado em Modelo (Langland et al 2015) na qual o projeto de um submarino é realizado por meio de modelos implementados em RdP PTD-OO. Permitindo com que engenheiros navais possam empregar uma metodologia de projeto distinta das já tradicionais, como a Espiral de Projeto.…”
