Information Integration for Simulation Based Design and Manufacturing

9422713哈德威克这个奖项是为了支持国家科学基金会的ENG-CEISE-IITA94倡议，国家挑战。这是工程局和计算机信息和工程局的一项联合倡议。这是爱荷华大学(ECS-9422722)和伦塞勒理工学院(ECS-9422713)在国家先进制造技术挑战赛领域获得的联合奖项。它为调查装配产品模型的要求提供资金，以支持基于模拟的机械系统并行设计。它为协调通过网络模拟产生的设计更改的方法的调查提供资金，并为评估ISO STEP标准(产品模型数据交换标准)的产品模型支持基于模拟的并行设计工具和网络集成基础设施的能力提供资金。将建立一个基于模拟的综合并行工程环境，使产品开发团队的所有成员能够模拟产品和工艺设计的性能和有效性，其逼真度可与使用物理原型实现的水平相媲美。所产生的基于仿真的设计环境将支持大规模机械系统应用的开发，特别是履带和轮式车辆系统。所生产的技术将减少测试的时间和成本，并在比传统开发方法所需的更短的时间内将高质量的产品推向市场。伦斯勒理工学院将负责创建产品模型，使用STEP在工程系统之间交换产品模型，并开发支持工作流控制和工程更改处理的工具。爱荷华大学将通过将他们的CAD和设计模拟工具与产品数据库集成，从多个设计角度执行模拟，生成工程设计更改，并与Rensselaer合作开发支持工作流程和工程更改处理的工具，来验证这些产品模型。皮奥里斯的卡特彼勒公司和PDEs，Inc.，一个包括波音、福特、通用电气、通用汽车、休斯、IBM和洛克希德公司在内的行业/政府联合财团将参与对进展的审查。

9422713 Hardwick This award is made in support of the NSF initiative ENG-CISE-IITA94, National Challenges. It is a joint initiative between the Engineering Directorate and the Computer Information and Engineering Directorate. This is a joint award to the University of Iowa (ECS-9422722) and Rensselear Polytechnic Institute (ECS-9422713) in the National Challenge area of Advanced Manufacturing Technology. It provides funding for an investigation into the requirements placed on product models of assemblies to support simulation based concurrent design of mechanical systems. It provides funding for an investigation into methods for coordinating design changes that result from simulations over a network, and funding for evaluating the ability of the product models of the ISO STEP standard (Standard for the Exchange of Product model data) to support simulation-based concurrent design tools and a networked integration infrastructure. An integrated simulation-based concurrent engineering environment will be constructed that will permit all members of a product development team to simulate the performance and effectiveness of product and process designs at a level of fidelity comparable to that which can be achieved using physical prototypes. The simulation-based design environment produced will support the development of large scale mechanical system applications, particularly tracked and wheeled vehicle systems. The technology produced will reduce the time and cost of testing and introduce high quality products into the market in a shorter time than that required by conventional development methods. Rensselaer Polytechnic Institute will be responsible for creating the product models, exchange of product models between engineering systems using STEP , and development of tools to support work flow control and engineering change processing. The University of Iowa will verify these product models by integrating their CAD and design simulation tools with the product databases, performing simulat ions from multiple design perspectives, generating engineering design changes, and working with Rensselaer to develop tool to support work flow and engineering change processing. Caterpillar Inc. of Peoris, and PDES, Inc., a joint industry/government consortium including Boeing, Ford, General Electric, General Motors, Hughes, IBM, and Lockheed will be involved with the review of the progress.
