Abstract:

The traditional centrifuge system usually uses a high speed, high precision single-axis rotator system to achieve one-way precise simulation of unidirectional centrifugal acceleration in a broad range. Nowadays, in order to realize immense three-axis normal overload of an aviation apparatus in three dimensions, an advanced three-axis centrifuge system was proposed. The high precision three-axis rotator was composed of a foundation and three rotational axes. It succeeded in simulating normal acceleration overload by regulating speed of outer axis, and precise position control of inner and middle axis. Based on the configuration above, a mathematical model of a three-axis centrifuge system was built; related kinematics simulation and theoretic calculation were analyzed. Given the three directions overload of x,y,z, offset angle of internal axis, middle axis and rotation speed of outer axis was solved inversely by means of the force-balance equation. In the end, through the analysis of dynamics simulations, correctness and effectiveness of the new centrifuge system configuration were validated further.
