Spacecraft must withstand rigorous mechanical environment experiences such as acceleration, noise, vibration, and shock during the process of launching, satellite-vehicle separation, and so on.In this paper, a new spacecraft multifunctional structure Conditioner concept designed by us is introduced.The multifunctional structure has the functions of
In order to improve fuel economy, the number of gears in the hydraulic automatic transmission of heavy-duty mining trucks is continuously increasing.Compared with single-transition shifts, double-transition shifts can optimize the structure of multi-speed transmissions, but the difficulty of control will also increase.In this paper, a dynamic model
Aviation Maintenance industry, Repair and Overhaul (MRO) procedures need to keep up with the technological evolution and evolve from the 2D support to the 3D.The available manuals for learning and training MRO tasks rely much on old 2D drawings and lists of maintenance steps to be performed sequentially.However, these are complex actions that requi
