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.

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。添加剂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成品中并损害热交换器的性能，则可能会引起问题。振动用于从系统中去除未使用的粉末。为了设计产品的最佳振动响应以去除这种粉末，必须能够理解产品的振动特征，这将是ASDEC将为项目所承担的关键作用。莱斯特大学的高级结构动力学评估中心（ASDEC）是通过非contsact方法来衡量复杂组成部分和结构振动的独特设施。 ASDEC在振动的测量，评估和分析中具有世界领先的系统和能力。对于这个项目，我们有能力以高达1MHz的非接触和非结构方式测量表面振动。 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中的便携式激光振动系统的组合。 3D激光振动设备将允许在我们的项目合作伙伴将生成的复杂结构上以无与伦比的细节和准确性进行可重复的测量。使用其他测量技术将无法实现这些测量。组件振动的模态分析将用于优化粉末摇摆，因此可以优化制造路线。增材制造具有很高的吸引力，因为它允许使用常规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，主要人员在振动，声学工程和开发以及信号处理和分析方面还具有40年的综合经验。
