High Performance Computing in the Design of Lightweight Army Vehicle Components

Under funding from DARPA, AlphaSTAR conducted a pilot study on leveraging High Performance Computing (HPC) for the design of durable and reliable military ground vehicles. It identified challenges for reliable and cost affordable design of Army vehicle components for:

  • Reduced weight and increased durability and reliability of key military vehicle components and systems as well as keeping cost down
  • Progress beyond analysis of vehicle component subsystem in isolation, which can lead to additional design cycles and expensive physical prototype testing
  • Move toward whole-vehicle modeling and analysis to provide increased design yields and reduced operational and manufacturing costs
  • Reduce the number of parts (via consolidation)
  • Reduce vehicle breakdowns, decrease fuel consumption, and extend vehicle lifespan
  • Leverage HPC to provide robust design capability of complex automotive structures by applying coupled durability-reliability-optimization solution to insert light weight materials in components of military vehicles
  • Optimize product performance by eliminating subsystem modeling in isolation to improve reliability and Durability and Damage Tolerance (D&DT)
