The aim is to develop a multidisciplinary 'design tool' that encompasses the state-of-the-art knowledge in noise source identification and transmission from enclosed generator sets, for more competitive environmental noise performance. Currently, within the UK based power generation industry, there are no design tools available that have the capability to optimise the design of cluttered enclosures for noise reduction at minimum manufacturing cost, in addressing the noise directive 2000/14/EC. Quantitative information about the performance at conceptual design stage is not known. Expensive mock-ups have to be manufactured to determine their performance, which adversely affects the lead-time and profits. Virtual acoustic validation and costing of manufacture for early conceptual design of power generating sets is very challenging. Specifically there are no tools on the market that link conceptual design parameters, acoustic analysis of those parameters and manufacturing cost. The market targeted for the project is the power generation industry, specifically sound attenuated generator sets, which is highly competitive and globally worth an estimated 2.7billion for products up to 2000kVA. The combination of Industry and Academia in this project will ensure an integrated capability for merging a virtual design and validation process, in terms of noise and manufacturing cost. The project will be led by FG Wilson using 6 Sigma DMEDI methodology. Having this capability at the design stage will result in a new understanding of the product, hence optimised performance weighted against cost. The developed flexible parametric design interface will provide a user-friendly platform to use the toolkit. The mix of partners involved in this project in terms of their role, expertise and strategic motivation has been a major consideration in setting up the consortium. The overall balance of partners includes large users, SMEs, software tool developers and academic experts. This mix represents a group of partners who each have a strong personal motivation in the project. The technical approach will involve the use of computational Indirect Boundary Element (IBE) and experimental approaches to simulate the radiation and scattering of the sound generated and transmitted through an enclosed diesel generator set, which includes an engine, an alternator, and cooling fans. In addition, methods for noise and vibration reduction based on damping and using multi-layer acoustic liner will be developed and implemented. LMS UK Ltd will supply their comprehensive suite of software for acoustic predictions and undertake development, while FG Wilson, the lead organisation, will supply generator sets, of different power ratings. Externally, a Ground Power Unit (GPU) supplied by Houchin Aerospace, will be used as an independent validation exercise. In general, this technology will be highly generic with wide scope ranging from automotive, aerospace, railway and marine through to the construction industry where trade-off in the cost of environmental noise reduction is such a relevant issue. The key innovation of this project hinges on the capture and exploitation of expert knowledge, from multiple technical disciplines, under one environment using numerical modelling techniques, empirical algorithms, industrial manufacturing cost data modelling, and experimentation for evaluation and design data generation for next stage. This will provide engineers with a tangible environment from which to synthetically design inherently cluttered enclosed generator sets, meeting lead-time, competitive cost targets and noise legislative targets.

目的是开发一种多学科的“设计工具”，该工具涵盖了噪声源识别和从封闭发电机组中传输的最新知识，以提供更具竞争力的环境噪声性能。目前，在英国的发电行业内，没有可用的设计工具可以优化以最低制造成本减少降噪的设计，以解决噪声指令2000/14/EC。关于概念设计阶段性能的定量信息尚不清楚。必须制造昂贵的模型以确定其性能，这会对交货时间和利润产生不利影响。虚拟声学验证和制造成本的早期概念设计集合非常具有挑战性。具体而言，市场上没有链接概念设计参数的工具，对这些参数的声学分析和制造成本。该项目的目标是发电行业，特别是声音衰减的发电机集，该集合具有高度竞争性，并且在全球范围内价值27亿美元的产品，最高为2000kVa。该项目中行业和学术界的结合将确保在噪声和制造成本方面合并虚拟设计和验证过程的综合能力。该项目将由FG Wilson使用6个Sigma DMedi方法领导。在设计阶段具有此功能将对产品产生新的了解，因此优化的性能与成本进行了加权。开发的灵活参数设计接口将为使用该工具包提供用户友好的平台。在该项目的角色，专业知识和战略动机方面，参与该项目的合作伙伴的组合一直是建立财团的主要考虑因素。合作伙伴的整体平衡包括大型用户，中小型企业，软件工具开发人员和学术专家。这种组合代表了一群合作伙伴，每个合作伙伴都有强大的个人动力。技术方法将涉及使用计算间接边界元素（IBE）和实验方法，以模拟通过封闭的柴油发电机集生成和传播的声音的辐射和散射，该柴油发电机集包括发动机，交流发电机和冷却风扇。此外，将开发和实施基于阻尼和使用多层声学衬里的噪声和振动减少方法。 LMS UK Ltd将提供其全面的软件套件，以进行声学预测和进行开发，而领先组织FG Wilson将提供不同功率评级的发电机组。在外部，Houchin Aerospace提供的地面动力单元（GPU）将被用作独立的验证练习。总的来说，这项技术将是高度通用的，其范围从汽车，航空航天，铁路和海洋到建筑行业，在建筑行业中，降低环境降噪成本的权衡是一个相关的问题。该项目的关键创新取决于使用数值建模技术，经验算法，工业制造成本数据建模以及下一阶段的评估和设计数据生成的实验。这将为工程师提供一个切实的环境，可以从综合设计固有地设计固有的封闭发电机集，达到交货时间，有竞争力的成本目标和噪音立法目标。
