Abstract:
An objective of the present invention is to provide a magnetorheological fluid used as a protection material. Another objective of the present invention is to provide a magnetorheological fluid showing a high shearing property by having an enhanced structure. To achieve the objective of the present invention, a method for manufacturing a magnetorheological fluid according to an embodiment of the present invention includes a first step for oxidizing iron-silicon alloy nanoparticles and a second step for coating a surfactant onto the oxidized nanoparticles and dispersing the nanoparticles in a dispersion medium. The iron-silicon nanoparticles contain 6.5 wt% of silicon added to iron.
Abstract:
PURPOSE: A speed deciding device of an the automatically moving vehicle and the automatically moving vehicle with the same and a driving speed deciding method of the autonomic moving vehicle are provided to the automatically drive an unmanned vehicle by determining maximum driving speed after determining power science of the automatic vehicle. CONSTITUTION: A speed deciding device of an automatically moving vehicle includes the following steps: setting a driving course of the automatically moving vehicle with a current position, constant positions through steering and control of speed; determining whether the vehicle can be traveled or not after evaluating overturning stability with 3D surface information and vehicle information; evaluating sliding stability of the vehicles with curvature of running trance and the horizontal acceleration of the vehicles; determining test sped of the vehicle; performing driving simulation; evaluating dynamic stability of the vehicle based on the result of the real-time dynamic mechanics interpretation; and determining driving speed of each trace using stability evaluation result and task loading speed.
