Introduction
1. Created low stress manufacturing system technology. The original low-stress manufacturing systems such as low-stress welding, additive materials, cutting and casting have been systematically implemented to achieve a revolutionary leap in the ability to maintain the accuracy of machined components.
The residual stress balance control model of components in the process of processing is proposed, which solves the theory and technology of deformation and cracking control of weak-stiffness aluminum alloy casting box processing, large-scale crankshaft heat treatment, energetic material curing, weak-stiffness metal cabin welding, and additive components. It has improved the performance and precision retention capabilities of many high-end equipment components, which is an international initiative.
2. Created multi-dimensional precision ultrasonic testing technology. Subvert the traditional ultrasonic testing, from two-dimensional to multi-dimensional, from qualitative to precise, and systematically realize the cross-generational development of ultrasonic testing of variable curvature and composite components.
A multi-dimensional high-frequency ultrasonic attenuation compensation model is proposed, which solves the problem for the defects of core components of cutting-edge equipment such as composite thermal insulation shells, complex-profile aluminum alloy components, and engine blades of "inaccurate measurement, Imprecision measurement, and unclear measurement" neck problem, the detection resolution and detection level are internationally leading.
3. Innovative in-situ detection and control technology of material properties. Created a technical standard system and national benchmark for ultrasonic detection and regulation of residual stress, and realized the essence of in-situ detection and regulation of residual stress of large components by serialization.
An in-situ detection and residual stress array control model is proposed to solve the field detection and evaluation of welding and machining residual stress in large-scale steel structures, large titanium alloy wings, Fuxing high-speed rail bogies, Daxing Airport main beam steel structures, and oil and gas pipelines and deformation control technical problems, detection resolution and detection capability are internationally leading.
