3. Milestones in the localization process
This set consists ofChina Heavy Machinery Research InstituteThe system he took the lead in developing has achieved three core breakthroughs:
1.Ultra-high pressure hydraulic system: Using graded pressure control technology, the working pressure reaches 45MPa, far exceeding the 32MPa standard commonly used in the industry.
2.Intelligent compensation algorithm: Through the real-time strain feedback system, material deformation errors can be automatically corrected, stabilizing test repeatability above 99.7%.
3.Digital twin platform: The supporting development of the virtual debugging system shortens the equipment installation cycle from the conventional 3 months to 18 days.

| Nuclear power equipment | 50 units/year | 480 million yuan | 50%+ |
5. Collection of expert opinions
Academician of Chinese Academy of EngineeringWang Guodongmeans: "This device isMulti-axis synchronization controlandBig data traceabilityIt has reached the international leading level in terms of technology and is expected to drive the domestic research and development efficiency of high-end materials to increase by more than 30%. "
Director of Baowu Steel Equipment DepartmentLi QiangRevealed: "After the system is put into production, the special steel test cycle has been compressed from the original 72 hours to 26 hours, which can save comprehensive costs of more than 20 million yuan per year."
It is worth noting that this system has obtained23 invention patents, the localization rate of key components exceeded 95%, including servo valve groups and high-precision sensors that have long relied on imports. The industry predicts that with the second batch of equipment rolling off the production line in 2024, my country is expected to become the third country in the world with the ability to export 10,000-ton material testing systems.
