According to the characteristics of spacecraft and technical demand,a method to realize three-dimensional rotation for five-DOF docking buffer table is studied.The analysis shows that three-axis test table is suitable to the whole system. The paper gives the relevant solution to the key problems in the design of three-axis test table. With the application of fuzzy element theory, three-axis table frames are designed in light weight, high stiffness and intensity as well as suitable to high impact. The weight of frames decreases by 8.7 %. According to the docking requirement of initial attitude, a three-dimensional attitude adjusting and locking mechanism with simple adjustment,rapid unlocking, light weight and safety is presented.The computational models and results are given.
