| In recent years, high-speed rail as a representative of rail transportation has been an unprecedented development, which not only brought new development opportunities to the entire rail transport, but also challenges did. RGV(Rail Guided Vehicle) is one of the many branches of rail transport, has been widely used in various industries, it is one of the key members of the modern logistics system.The subjectrelies onthe digitized factory project that casts the key components of the railway transportation, which is contracted by the company. The requirements of all the indicators in the project are higher than the one of the common foundry. Especially in the manufacturing process, the numerical control rate reaches 87.6%, product qualified rate reaches 98%, comprehensive energy consumption is 0.342 tce/ton Which is 22% lower than the domestic standard. To meet the requirements of the project, we redesign the heavy haul switch RGV to replace the traditional RGV, and obtain a new logistics system.RGV is the core of the new system, so it is critical tocontrolits movement characteristics, particularly to control its movement precision.The subject is to research the relationship between wheel-rail interaction and RGV Serpentine movement characteristics with rail transitdynamics theory and simulation analysis of techniques of SIMPACK, includes bellow list:(1) Establishing the RGVdynamics simulation model SIMPACK requires, using Pro/e, SIMPACK and other modeling software to establish the RGV model, and using Auto CAD and other software to obtain RGV wheel tread profile.(2) Using SIMPACKobtained the relationship between equivalent conicity and RGV serpentine movement characteristics.(3) Using SIMPACKobtained the relationship between wheel-rail nominal clearance and RGV serpentine movement characteristics.(4) Comprehensive analysis of equivalent conicity and wheel-rail nominal clearancewith RGVserpentine movement characteristics, and tested. |
