NIO looked at other testing labs for performing the material characterisation tests to provide the types of data required, but Artur states, “there is nothing like HBK’s AMCT lab that provides the entire package” both in terms of the available testing expertise but also the ability to deliver a materials database that could be used directly and easily in nCode software.
With the complexity of mixed materials used in modern automotive structures, there was a wide range of material characterisation testing required: from base material testing at different thicknesses, seam welds, laser welds and also hybrid jointing techniques including adhesives with spot welds in steel and adhesives with rivets in aluminium. A major reason why NIO selected the AMCT was the level of technical support given by HBK throughout the process, including the drawing up of the required matrix of tests. Close collaboration on the process delivered high quality materials data that could be used directly in nCode DesignLife.
nCode DesignLife also became the choice for durability CAE across the organization due to the value for money using the versatile Prenscia Access token licensing. Measured “road load” time series data is being post-processed by other groups in NIO using nCode GlyphWorks and there were therefore advantages in using common tooling.
