Tohoku University Graduate School of Engineering, Graduate School of Information Science and NEC Corporation announced the start of research and development of the material integration system using NEC's vector supercomputer SX-Aurora TSUBASA to accelerate the development of aviation carbon fiber reinforced composite materials (CFRP). This research and development was carried out under a national project "Cross-sector Strategic Innovation Promotion Plan" led by the Cabinet Office of Japan. , Can save up to 50%.
In the field of aerospace composite materials, Japan produces a variety of materials with excellent properties. But developing these materials requires a lot of time and expense. Currently, digitization is advancing globally, and the delivery time of products to the market needs to be shortened. Therefore, it is urgent to reduce development costs and development time.
In order to effectively develop high-performance composite materials in a short period of time, a variety of academic knowledge that combines strategic research and development, such as materials science and information science, is needed, not just relying on traditional methods and professional knowledge of routine experiments.
The purpose of this research and development is to create an integrated system capable of digitally developing CFRP for aerospace structures using simulation tools developed by SX-Aurora TSUBASA vector supercomputer of Northeastern University and NEC.
Specifically, through the execution of simulation code on a supercomputer, the mechanical response analysis, material selection, structural design and other high-speed multi-scale analysis can be performed from the molecular level to the aircraft wing and fuselage. By using the system as an integrated simulation platform, tailored material development can be carried out to more effectively meet the needs of aviation manufacturers.
The system is divided into three aspects:
1. Develop a multi-scale simulation platform (Professor Fuyong Okabe, Graduate School of Engineering, Northeastern University)
Using the results of scientific research on composite materials, Tohoku University has developed various CFRP simulation tools together with companies participating in Japan's "cross-sector strategic innovation promotion plan." In addition to aircraft, the integrated system developed in this research and development will also be applied to various vehicles in the future.
2. Application of high-performance computing technology (Professor Hongming Xiaolin of Northeastern University Information Science)
The simulation program for the material integration system of the SX-Aurora TSUBASA vector supercomputer will be vectorized and parallelized to greatly reduce the execution time of the simulation program. This research emphasizes the participation of the company's cooperation to accelerate the implementation of the plan.
3. Use supercomputer for system construction (NEC)
The SX-Aurora TSUBASA supercomputer consists of a vector engine that executes high-performance simulation programs and a vector host that performs various processes. This research and development utilizes NEC's supercomputer technology and system construction expertise to systematically simulate the program through the SX-Aurora TSUBASA supercomputer. Material integration systems combine data science and optimal material design.
