Minimodal: Dimensional Domain Of Miniature Shipping Containers For Intermodal Freight Transportation, Lee Stapley
Minimodal: Dimensional Domain Of Miniature Shipping Containers For Intermodal Freight Transportation, Lee Stapley
Ursidae: The Undergraduate Research Journal at the University of Northern Colorado
This study explores the feasibility of miniature shipping container usage within existing intermodal transportation (IT) supply chains. Smaller intermodal container shipments may help realign freight shipments with the most efficient transportation mode, rail. These containers embolden the dimensional domain (DD) of shipping. The shipping container dimensional domain (container size variation and modal fluidity) is widespread and results in shipments that are often larger or more infrequent than needed. The DD impacts transport mode, shipping frequency, shipment velocity, intermodal supply chain accessibility, and regional shipping networks. This study suggests that container size impacts the DD and, therefore, mode choice. As miniature …
Simulation And Verification Of Feasibility For The Torsional Vibration System Test Scheme, Yin Meng, He Yun, Zhigang Xu, Shixuan Zhang
Simulation And Verification Of Feasibility For The Torsional Vibration System Test Scheme, Yin Meng, He Yun, Zhigang Xu, Shixuan Zhang
Journal of System Simulation
Abstract: To test the loading accuracy of the directional device for the experiment system, a test scheme of torsional vibration system is proposed. To verify the feasibility for assessing the loading accuracy through the test scheme, a dynamics and control system model is established and simulated in the condition of ignoring torsion bar flexibility and friction; an Adams model is established and simulated in consideration of the torsion bar flexibility and friction. Both simulation results are obtained and analyzed. When the load torque amplitude reaches 30Nm, the disturbance torques under a certain frequency are all below 2Nm, which meets …
