With the application of multi-disciplinary knowledge synthetically, such as the calculation of the multi-body dynamics, the structural mechanics, the impact theory and so on, a visual virtual dynamic prototype model about rolling and pitching simulator of spacecraft docking test table in the docking process is built on ADAMS/Solver platform. An integration of UG-MATLAB-ADAMS-ANSYS simulation environment is realized in the process of building prototype models.
With dissolved air floating simulation device, the influence factors on floating efficiency, such as atmospheric pressure,dissolved tolerance, the air-oil ratio, mineralization degree, pH value, coagulant, oil content of waste water and temperature, etc. are researched systematically. Increasing atmospheric pressure and dissolved tolerance, controlling pH value to be 6-8, mineralization degree to be 3% and right amount of coagulant(PAC:50-70 mg/L)can get better degreasing efficiency.
The deferent voltage virtual value range of the electric power system harmonics simulator rig is 0～100V and deferent current virtual value range is 0～3A , which accord with the PT. The electric power system harmonics simulator rig is required to be of high power, high efficiency and little waveform distortion.
The dissertation introduces the TMS320LF2407, which is the control core of the electric power harmonics simulator rig with powerful operating ability and abundant interior resources. If it is used in the electric power harmonics simulator rig, it can realize digital control .
Because of special use conditions of the bearing, the friction torque of the attitude simulating device are test, data shows that the friction torque of the passive docking simulation test facility is 5.6 N·m, the active's is 1.32 N·m.
In this research, polyaluminium chloride(PAC) and natural organic flocculant CG_A were applied to remove superfine particulates (less than 5 μm) from oil field wastewater in a dynamic simulating device which consisted of spiral_flow mixer, fluidized sedimentation tower and sand filter.
