The human centrifuge carries out sustained G_load simulation through three degrees of freedom rotation movement,which is widely used in pilot G_load endurance training and aviation medical research.The simulation accuracy of the pre_programmed G_load curve of the human centrifuge directly affects the training and research results.This paper mainly focuses on the pre-programmed G_load curve design and simulation algorithm of the human centrifuge.A design model of linear G_load rate curve and nonlinear G_load rate curve of human centrifuge is established.Based on this,the G_load algorithm based on curve reconstruction is proposed.The G_load curve design method and simulation algorithm were tested through simulation analysis.The results show that the target G_load and simulation G_lad match well,and have good accuracy and practicability.
