Tailorable and Adaptive Connected Digital Additive Manufacturing (TACDAM)

该项目的目的是通过增材制造为热交换器创建复杂的设计。增材制造将使用激光烧结的金属粉末。如果未使用的粉末保留在制造的产品中并损害热交换器的性能，则会导致问题。振动用于从系统中清除未使用的粉末。为了设计出最佳的产品振动响应，以去除这些粉末，了解产品的振动特性是至关重要的，这将是ASDEC在该项目中承担的关键角色。莱斯特大学的高级结构动力学评估中心（ASDEC）是一个独特的设施，可以通过非接触方法测量复杂部件和结构的振动。ASDEC在振动测量、评估和分析方面拥有世界领先的系统和能力。对于这个项目来说，至关重要的是，我们能够以非接触和非破坏性的方式测量高达1MHz的表面振动。ASDEC结合了Robovib系统、LMS模态分析和虚拟相关工具以及可用于制造环境的便携式激光测振系统。3D激光测振仪设备将允许对我们的项目合作伙伴生产的复杂结构进行可重复的测量，其细节和精度无与伦比。使用其他测量技术无法实现这些测量。组件振动的模态分析将用于优化粉末振实，从而优化生产路线。增材制造非常有吸引力，因为它允许传统制造路线无法实现的产品结构和架构。除了ASDEC设施的能力外，主要工作人员在振动和声学工程和开发以及信号处理和分析方面拥有40年的综合经验。

The aim of the project is to create complex designs for heat exchangers by additive manufacturing. Additive manufacturing will use metallic powders which are laser sintered. The unused powder can cause issues if it is retained in the manufactured product and compromise the performance of the heat exchangers. Vibration is used to remove the unused powder from the system. In order to design the optimum vibration response of the product to remove this powder it is essential to be able to understand the vibration characteristics of the product and this will be the key role that ASDEC will undertake for the project.The Advanced Structural Dynamics Evaluation Centre (ASDEC) of the University of Leicester is a unique facility for measuring vibration of complex components and structures by non-contact methods. ASDEC has world leading systems and capability in the measurement, assessment and analysis of vibration. Critically for this project, we have the ability to measure surface vibration in a non-contact and non-distructive manner up to 1MHz. ASDEC combines the combination of a Robovib system, LMS Modal Analysis and Virtual Correlation tools and a portable laser vibrometry system that can be used in the manufacturing environment. The 3D laser vibrometry equipment will allow repeatable measurements to be performed in unparalleled detail and accuracy on the complex structures that will be produced by our project partners. These measurements would be unachievable using other measurement techniques. Modal analysis of the vibration of the components will be used to optimise the powder shake-out and therefore allow for optimisation of the manufacturing routes. Additive manufacturing is highly attractive as it allows structures and architectures for products that are unachievable by conventional manufacturing routes. In addition to the capability of the ASDEC facility, the key staff have 40 years combined experience in vibration and acoustic engineering and development as well as signal processing and analysis.
