238 historical review. This provides the data foundation for in-depth system analysis and forwardlooking decision-making. 2.3.5 Digital Twin Modeling Module This module is the core driver of the system's operation. Utilizing data from the SQL Twin Database and advanced modeling/simulation tools such as SolidWorks, Maya, and Unity3D, it constructs precise 3D digital twin models of the hydraulic supports and experimental platform that correspond exactly to their physical counterparts. By employing C# scripts, the dynamic behaviors of the digital models can be accurately driven, enabling real-time synchronization and interactive mapping with the states of the physical entities. 2.3.6 Data Visualization Module The Data Visualization Module is responsible for transforming complex data and models into intuitive visual representations. Through this module, the real-time status, historical trends, and simulation analysis results of the hydraulic supports and platform are dynamically presented in various formats such as charts, dashboards, and 3D model animations. This provides users with an intuitive and comprehensive interface for monitoring and analyzing the overall system performance. 3. SIMILARITY SIMULATION EXPERIMENT OF STEEPLY DIPPING HYDRAULIC SUPPORTS BASED ON DIGITAL TWIN 3.1 Experimental Method and Testing Means The experiment simulated combined static and dynamic loading on hydraulic supports using the large-scale test platform inclined at 45°. The dynamic loading was categorized into three types: vertical impact load, rear-pushing impact load, and side-pushing impact load. The detailed loading schemes for the static and dynamic loads on the two supports are presented in Table 1. Table1. Loading Schemes Loading inclination Loading type Application location Load magnitude (P0, Pr) 45° Static load Top beam 40kN,0kN Dynamic load Top beam 40kN,8kN Dynamic load Side guard plate of top beam 5kN,0.8kN Dynamic load Shield beam 3kN,0.48kN
