Deep Integration of Industry, Academia, and Research, Technology Empowers Product Upgrades – Jiangji Machinery Partners with School of Mechatronical Engineering, Beijing Institute of Technology to Aid Explosion-Proof Sphere R&D

In 2025, Jiangji Machinery Manufacturing Co., Ltd. took a solid step forward on its path of technological innovation and product R&D. To further enhance the technological content and market competitiveness of its core products, the company established a close cooperative relationship with the Explosion Laboratory of the School of Mechatronical Engineering at Beijing Institute of Technology (BIT). Leveraging the top-tier research capabilities and advanced simulation technology of the university, Jiangji successfully conducted finite element analysis simulations for its explosion-proof sphere product, significantly improving the design success rate of its main performance indicators and laying a solid foundation for product optimization and upgrading.

The explosion-proof sphere, as one of the company's key product lines, has core performance indicators directly related to public safety and the protection of users' lives and property, demanding extremely high design precision and reliability. Traditional R&D models rely mostly on experience and physical testing, leading to long development cycles, high costs, and difficulty in fully verifying performance under extreme operating conditions. Facing challenges from technological iteration in the industry and evolving market demands, Jiangji Machinery proactively sought external technical resources, turning its attention to the Explosion Laboratory of the School of Mechatronical Engineering at BIT, which has a profound foundation in explosion mechanics and protective engineering.

During the collaboration, the professor team from BIT fully utilized their professional advantages. Leveraging the laboratory's advanced finite element analysis software and mature explosion simulation technology, they conducted comprehensive, multi-condition simulation analyses on key performance indicators of the explosion-proof sphere. These included stress deformation, energy absorption, and structural stability under various explosive yields, positions, and environmental media. By establishing high-precision 3D models, the simulation team accurately reproduced the propagation laws of blast waves, the stress distribution of the sphere's shell, and the deformation process. They identified stress concentration areas, structural weaknesses, and performance redundancies in the traditional design, providing a scientific basis for product optimization.

The Jiangji R&D team worked closely with the BIT professor team, conducting multiple rounds of optimization and iteration on the sphere's structural design, material selection, and process parameters based on the simulation analysis results. By adjusting the shell curvature, optimizing rib layout, and selecting higher-strength materials, they effectively enhanced the sphere's blast resistance and energy absorption efficiency. Improvements to the sealing structure and cushioning design further strengthened the product's containment and safety.

This successful collaboration with BIT's School of Mechatronical Engineering represents a significant practice of Jiangji Machinery in implementing the "industry-academia-research-application" collaborative innovation concept. By introducing top-tier external research resources, the company not only overcame its own technological R&D bottlenecks but also established a modern R&D model of "theoretical analysis – simulation verification – physical testing – optimization iteration," providing replicable and scalable experience for future new product development and old product upgrades.

"The partnership with BIT has placed us at the forefront of industry technology," stated the head of Jiangji's R&D department. "The application of finite element analysis simulation technology has made our design more precise and scientific. We no longer rely on 'trial and error' but achieve optimal performance through data-driven methods." The professor team from BIT also spoke highly of the collaboration, believing that Jiangji Machinery's pragmatic R&D attitude and emphasis on technological innovation provide an excellent platform for transforming university research results, achieving a win-win situation for both industry and academia.

In the future, Jiangji Machinery Manufacturing Co., Ltd. will continue to deepen its cooperation with universities and research institutions, focus on industry technology frontiers, increase R&D investment, improve its innovation system, empower product upgrades with technology, drive corporate development with innovation, continuously enhance the technological content and market competitiveness of its core products, contribute more strength to the high-quality development of the industry, and build a solid technical defense line for public safety.
