Narrow Results

With the development of high temperature superconducting (HTS) maglev, studies on the running stability have become more and more significant to ensure the operation safety. An experimental HTS maglev vehicle was tested on a 45-m long ring test line under the speed from 4 km/h to 20 km/h. The lateral and vertical acceleration signals of each cryostat were collected by tri-axis accelerometers in real time. By analyzing the phase relationship of acceleration signals on the four cryostats, several typical motion modes of the HTS maglev vehicle, including lateral, yaw, pitch and heave motions were observed. This experimental finding is important for the next improvement of the HTS maglev system.

The paper discusses the complex and changing sediment environmental characteristics of cobalt-rich crusts and hydrothermal sulfide survey area in deep sea, and designs a new composite wheeled submarine vehicle with high over-obstacle capacity. The paper studies the composite wheeled submarine vehicle through analysing its possibility in all kinds of motion modes and experimental studies, obtains its main experimental data curves. The result shows that the composite wheeled submarine vehicle has a good possibility.
