Development and Verification of Overload Simulation Algorithms for Three-Axis Human Centrifuge
High-G training for pilots has commonly performed in the centrifuge-based flight simulators. In this paper,algorithms for overload simulation in a three-axis human centrifuge are developed and vali-dated. To this end,a kinematic model is established for kinematic analysis. A moving average algorithm is employed to smooth the inputs and to alleviate the abrupt changes in pitch and roll angles of the centri-fuge. An optimization algorithm for overload simulation is proposed and verified. The algorithm minimi-zes the error between the simulated and expected overloads to find the optimized kinematic variables of each axis of the centrifuge. Numerical results show that:(1) the moving average algorithm substantially alleviate the abrupt changes in pitch and roll angles of the centrifuge;(2) the proposed optimization al-gorithm is more accurate compared to traditional algorithms.
