This project articulates a long-term vision centered around the concept of an Internet-based Meta-Model Driven Distributed Workbench (M2D2W), and aimed at revolutionizing the ways in which MBS can assist engineers in the design and analysis of complex systems. It focuses essentially on an 18-month exploratory research effort whose two main objectives are to address a number of identified obstacles and challenges, and demonstrate the credibility of MBS for the engineering of civil and mechanical systems. For this purpose, the concept of a multidisciplinary M2D2W will be researched, a prototype built, and its potential demonstrated by applying it to the aeroelastic stabilization of the Bronx-Whitestone bridge. The stabilization study is to include the planned design of a new orthotropic deck, which when installed will lighten the bridge considerably, and the investigation of several mitigation procedures in anticipation of even poorer aeroelastic response characteristics.The main technical purpose of the M2D2W is to provide an open, multidisciplinary, scalable, interactive, and Internet-based simulation environment. The outcome of this research effort is expected to promote and enable a paradigm shift from closed single discipline analysis codes, to open, multidisciplinary, Internet-based,what-if simulation environments. This in turn will contribute to transforming MBS into a practical methodology for the engineering of civil and mechanical systems.***

该项目阐明了围绕基于互联网的元模型驱动分布式工作台 (M2D2W) 概念的长期愿景，旨在彻底改变 MBS 协助工程师设计和分析复杂系统的方式。它主要侧重于为期 18 个月的探索性研究工作，其两个主要目标是解决许多已确定的障碍和挑战，并证明 MBS 在土木和机械系统工程方面的可信度。为此，我们将研究多学科 M2D2W 的概念，构建原型，并通过将其应用于布朗克斯-怀特斯通大桥的气动弹性稳定来展示其潜力。稳定性研究包括新的正交各向异性桥面板的计划设计（安装后将大大减轻桥梁的重量），以及针对预期更差的气动弹性响应特性的几种缓解程序的研究。M2D2W 的主要技术目的是提供一个开放的、多学科的、可扩展的、交互式的、基于互联网的模拟环境。这项研究工作的成果预计将促进并实现从封闭的单一学科分析代码到开放的、多学科的、基于互联网的假设模拟环境的范式转变。这反过来将有助于将 MBS 转变为土木和机械系统工程的实用方法。***
