Design And Analysis Of Space Integrated Docking Interface

With the gradual deepening of human space exploration steps, direction for exploration of deep space has more demand, the spacecraft can only limited in low earth orbit flight around the earth and the most spacecraft are disposable, not upgrading and energy supply, and enhance the function of electronic components, with the rapid development of human science and technology, the development of new materials and high performance CPU, making the spacecraft was launched a few years ago could meet the demand.In order to have launch the on orbit spacecraft prolong service life and software upgrades or energy supply functions, puts forward a small spacecraft on orbit docking task, through small for ground launched to satellite on the orbit maintenance and upgrade, general butt for energy satellite to get close to a satellite in orbit, on orbit satellite capture mechanical arm to the energy supply satellite capture, trapping success will be placed to a predetermined position, and then connect the two mechanical, electrical, fluid interface, on orbit satellite for maintenance, and other tasks.This topic is in the energy supply for the first time, satellites are captured, sent to orbit satellite in a predetermined position, by docking interface capturing manipulator in its envelope space to the energy supply satellite secondary capture, capture after docking, and electrical interface and gas / liquid interface connection, on orbit satellite for upgrade and maintenance.This paper designed a new integrated mechanical interfaces, fluid interface, electrical interface space integration and docking interface, the use of three-dimensional design software of the interface model is constructed, followed by f inite element simulation software are analyzed, the results were compared to ensure the feasibility of the design.
