Abstract：To address the complex fault mechanisms and scarcity of fault samples in coal shearer height adjustment systems,an experimental platform based on virtual-physical interaction was proposed and constructed,to effectively acquire multi-source fault characteristic data.The platform utilizes multi-domain coupling modeling technology to achieve high-fidelity mapping of the physical system and ensures the safe operation of the physical entity through spatially optimized design of mechanical structures and sensor layouts.Relying on the collaborative operation mechanism of hardware and software subsystems,the platform dynamically couples the physical entity and the virtual simulation model.Typical fault simulation experiments and extreme working condition simulations were conducted based on the platform,and the consistency between virtual and physical fault data was evaluated using cosine similarity.The experimental results show that the similarity between real and simulated data is above 0.9,fully verifying the platform's robustness and its ability to generate accurate and effective fault data.Additionally,the platform can generate key fault characterization parameters that are difficult to be directly monitored in the physical entity,providing reliable multi-dimensional experimental data support and theoretical foundation for intelligent fault diagnosis of coal shearer height adjustment systems.
