SABRE system is led by Wang Binwen, an expert in the field of aircraft strength and director of China Aircraft Strength Research Institute. Taking the opportunity of high quality, independent and controllable, relying on domestic advantages, SABre system lasted four years to build with ingenuity. Based on years of independent research and development of the Institute of Strength, the software integrates the new theories and methods of computational mechanics in the last five years, the results of professional innovation and research on strength and the experimental data of aircraft development in the last ten years. The functions of the software cover the main needs of basic research, technological innovation and equipment development, and can replace similar foreign mainstream advanced software to achieve complete autonomy and control.
It is understood that the Strength Institute began to independently develop structural analysis CAE software in the 1970s, and adhere to independent innovation for a long time. In nearly 50 years of dedicated practice, A number of influential CAE software systems such as HAJIF series for aircraft structure analysis, VEP for aircraft structure vibration environment prediction, COMPASS for composite material structure analysis and optimization, YIDOYU for aircraft structure multi-constraint optimization have been developed, which solved the key technical problems in the development process of the model at that time, and successively won the national science and Technology Progress award six times. Has created a wide range of economic, social and military benefits. In the long-term independent research and development process, the institute has accumulated a number of CAE software core technologies and codes, and forged a software research and development team with strong technical capability and dare to fight hard.
In recent years, aiming at the bottlenecks and weaknesses that have plagued domestic structural analysis CAE software for a long time, such as algorithm robustness, user friendliness and computing resource adaptability, a digital strength system with "digital twin" and "V&V theory" as the core has been proposed and constructed, with "general analysis function group, special analysis tool chain, "Domestic data resource pool" as the goal, adopted the waterfall and agile development mode, designed the open TE8 unified layered software architecture, broke through a number of advanced algorithms, developed a number of general, special and database modules, formed a new SABRE system.
Our famous mechanics scientist, president of the Chinese Mechanics society, academician of the Chinese Academy of Sciences Fang Daning said that the release of SABRE system shows the national feelings and mission responsibility, and has great significance for the establishment of structural analysis CAE software ecological system. We hope that all parties rally strength, system layout and continue to advance. And calls on universities, research institutions and equipment enterprises to actively use, widely promote, take the initiative to feedback, and jointly build SABRE system gradually into the world's leading level of autonomous and controllable large-scale structural analysis CAE software. The SABRE system released this time has far-reaching strategic significance for ensuring the safety of Chinese equipment development system, and will certainly play an important role in basic research, technological innovation and equipment development.

At the conference site, dozens of units, including key aviation Ovens, industrial enterprises, colleges and universities, commercial companies and China Aircraft Strength Research Institute signed software demonstration application agreement, purchase contract, joint innovation and modeling contest agreement and sales agency agreement. This is a good start for SABRE systems to be widely used in education, industry and defense. The successful release of SABRE system indicates that the autonomous and controllable CAE software of large-scale structural analysis has achieved preliminary results, and also indicates that the application ecology of Chinese autonomous industrial software is gradually becoming mature.
