China Instrument Network: R&D of Advanced Testing Equipment Recently, the Ministry of Science and Technology's High-Tech Research and Development Center released the list of 2018 projects under the "Major Scientific Instruments and Equipment Development" plan. Among them, a key project titled "In-Situ Testing Instrument for Mechanical Properties of Materials" (Project No.: 2018YFF01012400) was approved. This initiative is led by China National Machinery Co., Ltd., marking a significant step forward in domestic scientific equipment development.
Founded in 1959, China National Machinery Testing Equipment Co., Ltd. has long been recognized as the leading technical and standardization center in China's testing machine industry. Known as the "cradle of China's testing machine technology," the company has consistently demonstrated strong innovation capabilities and advanced customization systems for specialized machinery. Its services span from component development to full-scale production and tailored solutions for the entire industry chain.
This project represents a major milestone for the company. It follows the earlier "Major Scientific Instrument and Equipment Development" project launched in 2012 and was successfully approved under the national "Major Scientific Instruments Special Project." The project received 14.59 million yuan in funding and will be implemented over a three-year period.
The main goal of the project is to address the performance testing needs of materials used in aerospace, aviation, and nuclear industries under high-temperature and high-frequency conditions. By overcoming key challenges such as mechanical property testing and micro-characterization under complex loads, the project aims to develop an in-situ testing instrument with independent intellectual property rights. The system will ensure stability, reliability, and localization of core components, along with software and database development. This will enable real-time monitoring of micro-mechanical behavior, deformation, damage modes, and performance evolution of materials under complex loading conditions.
The project has strict evaluation criteria, including a static tensile load range of 0–100kN with a resolution of ≤2N and accuracy of ±1%, a deformation measurement range of 0–100mm with a resolution of ≤10μm and accuracy of ±2%. For static bending, the load range is 0–10kN, with a resolution of ≤1N and accuracy of ±1%. Deformation measurement is 0–50mm, with a resolution of ≤5μm and accuracy of ±2%. The high-frequency fatigue load can reach up to 10kN at frequencies ≥20kHz. The temperature range is -20°C to 1100°C, with a control error of ±5°C. The imaging magnification for mechanical tests ranges between 500x and 1000x. Upon completion, the product must pass reliability tests, achieving an average time between failures of ≥3000 hours and a technical readiness level of 8. The project also aims to secure a number of intellectual property rights, including invention patents, standards, and software copyrights. It should also establish mass production capacity and define sales targets during project acceptance.
Through this project, the company aims to break through in-situ measurement technologies for static and dynamic mechanical properties of materials under complex and high-temperature conditions. In addition, it will promote engineering development, application demonstration, and industrialization efforts.
