Electrified Propulsion Systems: Digital Twin Based Design and Optimisation

数字化正在彻底改变整个产品生命周期：从开发、生产到测试、在线维护和回收。“数字孪生”(DT)技术将显著减少电力动力总成的开发时间、成本和风险：通过在虚拟环境中进行前期设计分析、优化和测试，而不需要多个原型。在其核心，DT是任何物理产品的表示，可以用作监控、模拟和优化设计和操作性能的试验场。李嘉图设想了一个我们都能过上可持续生活的世界。为了实现这一点，我们创造了以数字化为基础并由应用创新支持的产品和服务。这项计划的主要目标是评估DT技术对产品开发的影响。第二个目标是评估DT在该领域的产品维护中的应用。Ricardo将基于其在用于实时应用的动力总成降阶建模方面的专业知识，为虚拟产品维护提出创新的商业模式。数字孪生可以由三种类型的子模型组成：CAD、分析和物联网。在这个项目中，第一个重点将是为电气化动力系统中的每个关键子系统定义DT要求。第二个重点将是为满足这些要求的每个子系统开发数字双胞胎。第三个重点是各个子系统的集成，以创建电气化动力总成数字双胞胎。该系统级数字双胞胎将作为虚拟产品开发过程的一部分，用于电气化动力总成的设计和优化。里卡多相信，这个项目将产生三项创新。首先，对电气化动力总成各子系统的数字孪生进行了定义，包括模型层次结构、数据交换、历史数据管理和标准化接口。其次，使用自动模型缩减的简化模型，当需要小时间尺度的结果时，允许更快的交互。最后，使用数字双胞胎作为虚拟产品开发过程的一部分。

Digitalisation is revolutionising the complete product lifecycle: from development and production to testing, in-service maintenance and recycling. "Digital Twin" (DT) technology will bring a significant reduction in electric powertrain development time, cost and risk: through up-front design analysis, optimisation and testing in a virtual environment, without the need for multiple prototypes. At its core, a DT is a representation of any physical product that can be used as testing grounds for monitoring, simulating and optimizing design and operational performance. Ricardo has a vision of a world where we can all live sustainable lives. To realise this, we create products and services enabled by digitalisation and supported by applied innovation.The key objective of this project is to assess the impact of DT techniques on product development. A secondary objective is to evaluate the application of DT to product maintenance in this field. Ricardo will build upon its expertise in powertrain reduced order modelling for real time applications and propose innovative business models for virtual product maintenance.A Digital Twin can consist of three types of sub-models; CAD, Analytical and IoT. In this project, the first focus will be to define DT requirements for each of the key sub-systems within an electrified powertrain. The second focus will be developing Digital Twins for each sub-system that meet these requirements. The third focus is the integration of each sub-system, to create an Electrified Powertrain Digital Twin. This system level Digital Twin will be used, as part of the virtual product development process, in the design and optimisation of the electrified powertrain.Ricardo believe this project will yield three innovations. Firstly, the definition of a Digital Twin for electrified powertrain sub-systems, including model hierarchy, data exchange, historical data management and standardised interfaces. Secondly, simplified models using automatic model reduction, that allow faster interactions when results are required at small time scales. Lastly, the use of Digital Twins as part of a virtual product development process.
