Research on promoting innovation in the high-end equipment manufacturing industry through large scientific facilities in universities:Taking the environment and load coupling full-scale test as an example
[Objective]High-end equipment is increasingly facing the dual challenges of harsh service environments and increased payloads in the fields of technology and engineering.Large-scale scientific facilities are crucial for promoting the development of cutting-edge basic science and technological innovation,and universities are increasingly taking on the task of building and operating them."Major Engineering Material Service Safety Research and Evaluation Facility(MSAF)"is a national major science and technology infrastructure led by the University of Science and Technology,Beijing;it is the first large-scale scientific facility directly facing the main battlefield of the national economy.The MSAF has actively conducted service performance tests under complex working conditions for high-end equipment manufacturing by developing full-scale test devices to achieve real service conditions and coupling complex environments and loads.[Methods]It has played a vital role in promoting the integration and development of related disciplines and manufacturing domestic high-end equipment through material selection,new material application,design optimization,and reliability evaluation.Additionally,it has effectively accelerated the localization process in core technology research and product verification.This study summarizes the technological innovation of MSAF in full-scale environmental and load coupling experiments.We analyze practical cases of serving the high-end equipment manufacturing industry and propose suggestions on the mode and focus of the precise application of large-scale scientific facilities to serve the industry.The MSAF considers the complex service environment of engineering fields,such as petroleum and petrochemicals,marine engineering,transportation,mechanical equipment,and infrastructure,as the background and focuses on the key materials and components of major engineering and industrial equipment.It realizes an accelerated simulation of the entire failure process of key core components in the high-end equipment manufacturing process under actual working conditions to investigate the failure laws and mechanisms of major engineering materials and components in service environments.Basic and applied research on safety evaluation and life prediction has provided conditions to significantly improve the ability of China's engineering material service safety research and evaluation.Furthermore,this study investigates how MSAF's large scientific facilities can utilize world-class large-scale scientific experimental facilities to conduct experimental testing and research and development for industrial innovation and development.[Results]Significant progress has been achieved by developing a new research and development model with Chinese characteristics to address the high-end equipment manufacturing requirements of major scientific and technological infrastructures.Additionally,considerable strides have been made in utilizing large scientific facilities to provide precise services that support China's scientific and technological innovation,industrial transformation,and economic development.[Conclusions]The continuous expansion of services provided by this facility in advanced equipment manufacturing will significantly alter the prevailing situation in which developed countries constrain the safety evaluation of major engineering materials and structures in China.This will effectively promote the high-quality development of China's manufacturing industry and enhance its access to international markets.Additionally,MSAF innovation has successfully overcome key technological challenges related to the"scale environment time"multi-scale and multi-dimensional engineering material service safety evaluation series.This advancement has led to the construction of a technical system for engineering material service safety evaluation.This has greatly improved China's ability and standards in engineering material service safety evaluation,contributing to the achievement of independent and controllable core technology for safety evaluation services in China.Moreover,this initiative has positioned China at the forefront of international development.Thus,the goal of cultivating innovative professional talent is of great significance.
