The Method Discussion of Controlling the Parasitic Accelerations Produced by Three Axial Human Centrifuge when Simulating Pure Gz

摘要

The simulation of pure Gz acceleration always is one of the main simulation contents. When regulating of centrifuge Gz precision requirement, the max parasitic accelerations values which are allowed to appear at other directions such as Gx, Gy directions are also regulated at the same time. This study based on motion model of three axial human centrifuge, design smoothing transition section for anterior segment of centrifuge acceleration curve, makes computer simulation of different smoothing times and smoothing time based on Euler recursion method, and the simulation results are made compared. Results show that, this method can effectively inhibition the values of parasitic accelerations of x and y directions by slowing down the change speed of acceleration, and torque required by the system reduces after smoothing. This method can be as reference basis when designing other methods of inhibiting parasitic accelerations. About torque change, this point should be given enough attention in practical application of system designing.
