Industry/University Cooperative Research Center for Virtual Proving Ground Simulation: Mechanical and Electromechanical Systems

为未来产品开发新车辆和设备的长时间和高成本正变得令人望而却步。公司和政府越来越多地转向模拟，以确定新产品设计的有效性。开发虚拟试验场的研究将为产品测试提供必要的数据，而无需生产昂贵的原型。爱荷华大学和德克萨斯大学奥斯汀分校联合成立了一个工业/大学合作研究中心（I/UCRC），用于虚拟试验场仿真：机械和机电系统。大约有12家公司和联邦机构承诺成为该中心的成员。该中心符合产学研合作研究中心计划的所有要求。多大学中心汇集了来自三所大学（其中两所将获得NSF I/UCRC基金）的研究团队的独特能力，以解决任何一所学校都无法单独解决的研究领域。该中心将利用爱荷华大学开发的车辆系统仿真的独特能力和设施，作为先前NSF I/UCRC机械系统仿真和设计优化的一部分。这些能力，加上爱荷华大学新增的用于驾驶员在环实时仿真的国家高级驾驶模拟器（NADS），再加上德克萨斯大学奥斯汀分校在机电系统仿真和设计方面的专业知识以及奥本大学在车辆地形仿真方面的专业知识，将使拟建的中心能够进行虚拟试验场仿真。虚拟试验场模拟结合了车辆与其移动表面之间相互作用的动力学。该研究计划包括由中心会费资助的核心研究项目，以及由成员公司和联邦机构资助的试点项目。拟开展的核心研究项目有：车辆与设备虚拟试验场建模与仿真、虚拟试验场建模、动力系统仿真、轮胎/履带-土壤相互作用建模（奥本大学）、虚拟试验场仿真数值方法、机电系统建模、虚拟试验场环境下的电力系统仿真、基于仿真的电力系统设计、基于仿真的电力系统测试与评估。这些大学开展试点项目的大部分资金将来自国防部和其他联邦机构。这些项目都在中心研究计划的基本目标范围内。它们极大地扩展了中心的研究基础，有效地引导了研究方向，以满足产业需求。提出的试点项目有：基于仿真的混合动力汽车设计、农业装备虚拟试验场、建筑设备虚拟试验场、军用车辆虚拟试验场、火箭系统虚拟试验场、先进机电设备仿真设计、关键电力系统部件仿真测试与评估。国防部和其他联邦机构将在五年内为试点项目提供资金支持。主任（首席研究员）和联合主任及其同事都是杰出的研究人员，具有管理本中心的独特资格。该中心的费用由ENG/DMII的工程设计项目分担，并将与美国国家科学基金会参与的新一代车辆跨部门合作计划（PNGV）协调。项目经理建议爱荷华大学每年获得43,000美元的奖励，为期五年。在每12个月结束时，项目总监/和/或工程教育和中心部的部门总监将根据一系列更新标准对中心进行审查，包括以下内容：1)行业/大学互动的发展程度；2)支撑基础的发展程度；3)一个强有力的研究项目正在发展的程度。如果审查令人满意，项目主管将建议支持下一阶段的持续奖励。建议在五年内为试点项目增拨9 826 236美元。国防部和其他联邦机构的试点项目资金将通过一系列独立的机构间资金转移进行，由合作的联邦机构确定每个项目和任务以及分配给它的资金总额。作为上述内容的一部分，国防部高级研究计划局建议为最初的试点项目提供为期一年的60万美元奖励。建议为预期的联邦机构中心成员每年额外授权40万美元，为期五年。

EEC-9704242 Haug, Ed/U of Iowa The long time and high costs of developing new vehicles and equipment for future products are becoming prohibitive. Companies and the Government are increasingly turning to simulation to determine the effectiveness of the design of new products. Research to develop a virtual proving ground will provide the data necessary for product testing without producing expensive prototypes. The University of Iowa and the University of Texas at Austin have joined together to form an Industry/University Cooperative Research Center (I/UCRC) for Virtual Proving Ground Simulation: Mechanical and Electromechanical Systems. About a dozen companies and Federal agencies have committed to become members of the Center. The Center meets all requirements of the Industry/University Cooperative Research Centers Program. The multi-university Center brings together unique capabilities of research teams from three universities (two of which will receive NSF I/UCRC funds) to address research areas that none of the schools could address alone. The Center will utilize unique capabilities and facilities for vehicle system simulation developed at the University of Iowa as part of a prior NSF I/UCRC in Simulation and Design Optimization of Mechanical Systems. These capabilities, with the new addition of the University of Iowa's National Advanced Driving Simulator (NADS) for the driver-in-the-loop real-time simulation, combined with expertise at the University of Texas at Austin in electromechanical system simulation and design and expertise at Auburn University in vehicle-terrain simulation, will allow the proposed Center to do virtual proving ground simulation. Virtual proving ground simulation incorporates the dynamics of the interaction between a vehicle and the surface on which it moves. The research program consists of core research projects funded from center membership fees, and pilot projects funded by both member companies and Federal agencies. The proposed core resea rch projects are: Vehicle and Equipment Virtual Proving Ground Modeling and Simulation, Virtual Proving Ground Modeling, Dynamic System Simulation, Tire/Track-Soil Interaction Modeling (Auburn University), Numerical Methods for Virtual Proving Ground Simulation, Electromechanical System Modeling, Power System Simulation in a Virtual Proving Ground Environment, Simulation-Based Design of Power Systems, and Power System Simulation-Based Testing and Evaluation. The bulk of the funding for the universities to work on pilot projects will come from the Department of Defense and other Federal agencies. These projects are within the fundamental goals and objectives of the Center's research program. They greatly expand the Center's research base and effectively guide the direction of the research to meet industrial needs. The proposed pilot projects are: Simulation-Based Design of Hybrid-Electric Vehicles, Agricultural Equipment Virtual Proving Ground, Construction Equipment Virtual Proving Ground, Military Vehicle Virtual Proving Ground, Rocket System Virtual Proving Ground, Simulation-Based Design of Advanced Electromechanical Devices, and Simulation-Based Testing and Evaluation of Critical Power System Components. The DoD and other Federal agencies will support pilot projects with funds as they become available during the five year period. The Director (Principal Investigator) and co-Director and their colleagues are eminent researchers and uniquely qualified to run this Center. The Center is being cost shared by the Engineering Design Program of ENG/DMII and will be coordinated with NSF's participation in the interagency Partnership for a New Generation of Vehicles (PNGV) Program. The Program Manager recommends the University of Iowa be awarded $43,000 annually for a five year continuing award. Near the end of each 12-month period, the Program Director / and or the Division Director of the Engineering Education and Centers Division will review the Center on a number of renewal criteria including the following: 1) the extent to which the industry/university interaction is developing; 2) the extent to which the support base is developing; 3) the extent to which a robust research program is developing. If the review is satisfactory, the Program Director will recommend support for the next period of this continuing award. An additional authorization of $9,826,236 over five years is recommended for pilot projects. Funding of the pilot projects from the DoD and other Federal agencies will occur through a series of separate interagency transfers of funds by the collaborating Federal agencies, identifying each project and task and the total amount of funds that are allocated to it. As part of the above, $600,000 is recommended for a one-year award for an initial pilot project with funds provided by the Defense Advanced Research Projects Agency. An additional authorization of $400,000 annually for five years is recommended for anticipated Federal agency Center memberships.
