The Railway Cargo Loading Modeling And Dynamics Simulation

With the development of air、shipping and highway transport, rail transport faces increasing competitive pressure in the transport markets, rail transport is facing more and more kinds of test. Improving train freight performance, reasonably planning of rail transport lines, as well as improving the Load Securing level are condutive means to improve the market competitiveness. This paper focuses on Load Securing railway freight transport performance, research on Load Securing modeling and dynamic simulation analysis to improve cargo transportation security and stability.Firstly, the paper introduces the background and significance of Load Securing railway freight transport, and described the current situation at home and abroad; starting from rules of Load Securing railway freight transport, devising a detailed classification of goods, as well as the basic technical conditions in the choice of loading vehicles, freight high center of gravity and load line are introduced. And make a depth discussion about the operating performance of the rail freight vehicles which is focused on narrative truck derailed, overturning the occurrence and evaluation indicators.Secondly, the method of thinking and technology roadmap of modeling and simulation analysis of truck model, cargo model and line model which are based on SolidWorks and ADAMS software platform is introduced. According to the existent cargo loading reinforcement program, using Solidworks to make the three-dimensional solid modeling and assembling, and then sent to the ADAMS to make kinematics simulation analysis, by adding pulse excitation and harmonic excitation, analysis the variety of displacement, velocity and acceleration of changes of the loaded vehicle in both excitation to improve the efficiency of rail freight loading in the future to explore a better method of loading.Finally, the paper generalized the railway cargo loading modeling and dynamic simulation studies, and conducted a preliminary analysis of the relevant difficult problems, and then forecast the future of railway cargo loading modeling and dynamic simulation study.
