Abstract:This paper investigates the persistent problems in traditional equipment testing, including lifecycle stage fragmentation, severe data silos, disconnection between virtual and physical testing, difficulty in iterative optimization due to open-loop operation, challenges in reproducing extreme operating conditions, and imbalance between test cost and efficiency. Technical bottlenecks such as insufficient coverage of physical testing, delayed decision-making throughout the entire process, unreliable test credibility, and inability to retain and reuse domain knowledge are analyzed. By employing technical approaches including digital thread integration, digital twin mapping, multi-domain unified modeling, model calibration, data fusion evaluation, and feedback control theory, a closed-loop management architecture and operational model covering the entire equipment lifecycle—"requirements —testing—evaluation—optimization—revalidation"—is constructed. This framework enables integrated management of digital testing across the whole lifecycle stages of equipment demonstration, development, production, operation, and decommissioning, facilitating bidirectional data flow, virtual-physical fusion validation, and intelligent closed-loop iteration. The relevant technical achievements address the core bottlenecks of traditional equipment testing, providing both a theoretical framework and technical support for the digital transformation of equipment test and evaluation as well as the enhancement of combat effectiveness.
