Abstract: Optimizing a vehicle structure for crashworthiness in the early concept design phase is challenging since the design evolves frequently, and the simulation takes too long to meet the design changes' frequency. Therefore, we need a workflow to follow the design changes and provide timely feedback. Hence, we performed a PoC project collaborating with Dassault Systèmes SIMULIA to explore the workflow that optimizes a structure using an abstracted model and a metamodel. We then verify the design with a few runs of an FE model using an algorithm that makes the FE model run faster.
Biography: YongHa Han has been working for Hyundai Motor Group for 25 years in the field of vehicle crash simulation. He received his M.S. from the Seoul National University. He is currently in charge of the Virtual Technology Innovation Research Lab and is focused on advanced simulation methodology development. YougHa is trying to create the most realistic simulations possible in virtual reality to save on testing costs as well as time.
Yangwook Choi is an expert in crashworthiness simulation with over 30 years of experience, and developing various methodologies and supporting the customers. He received his M.S. and Ph.D. from the Ohio State University. Yangwook started his career as a crash/safety engineer at Hyundai Motor Company in Korea and then continues at Dassault Systèmes SIMULIA after completing his Ph.D. degree. He has recently been working on optimizing crashworthiness using an abstracted model and metadata for the conceptual design phase.
