Comparative study to identify and bridge the gap between physical and virtual durability testing on a real durability track and its digital twin of the vehicle/ road surface.

India has seen a significant boost in automotive research and development, specific to ADAS and electric vehicles. To test these innovations, without a full working prototype, vehicle manufacturers are relying on virtual models to better fine tune the design parameters. For this, there is a real requirement of digital twins of proving grounds. This virtual testing surfaces will help in reducing test costs, test times and increase iteration counts, leading to fine-tuned prototype vehicle and finally a market leading product. NATRAX is already playing a crucial role in the homologation and development of these technologies, on their test tracks. Recognizing the need to assist in virtual testing for Indian automotive manufacturers, NATRAX is developing virtual proving grounds to complement physical testing and reduce the development time. This paper aims to have a comparative analysis of dynamic parameters between virtual track testing and actual track testing on a virtual representation of durability road surfaces. The aim of this study is to identify and bridge the gap between results from physical durability testing and virtual durability testing, using the same digital twin road surface. For the study, the parameters identified will be compared between the digital twin and equivalent physical testing to establish a correlation under specified conditions, leading to a comparative matrix for the durability testing.
