This book examines the strategies adopted by local governments to obtain excess construction land quotas in the face of the central government's strict land management system. It applies game theory, principal-agent theory, collective action theory, and competition and collusion theory to analyze the trade-offs and constraints faced by local governments under the existing institutional framework. It also empirically tests the imitative competitive strategy of land violation and the institutional collusion strategy of land development rights trading using spatial panel model and Tobit...

This book focuses on the application of virtual reality (VR) technology in mining machinery. It gives a detailed introduction to the application of VR technology in virtual assembly, virtual planning, and virtual monitoring. Based on the theory of digital twin, VR technology and collaborative control technology are applied to coal mining machinery equipment, which lays a foundation for the digitalization and intellectualization of coal machinery equipment and broadens the application scope of virtual reality technology in the mechanical engineering field. Through the application of VR...

This book introduces the engineering application of the discrete element method (DEM), especially the simulation analysis of the typical equipment (scraper conveyor, coal silos, subsoiler) in the coal and agricultural machinery. In this book, the DEM is applied to build rigid and loose coupling model, and the kinematic effect of the bulk materials, the mechanical effect of the interaction between the bulk materials, and the mechanical equipment in the operation process of the relevant equipment are studied. On this basis, the optimization design strategy of the relevant structure is...
