摘要
航天员月球车驾驶技能地面训练需要模拟逼真的运动感知特性,其关键在于掌握地面与月面驾驶运动感知的差异.笔者建立了高度逼真的月球车驾驶运动仿真场景,模拟月球车驾驶运动的地月差异;开发了以空间定向模型为框架的人体运动感知软件,仿真比较了月球车驾驶前向运动感知的地月差异.结果表明,月面环境下月球车加速度变化范围减小、加减速缓慢且易发生侧滑;视觉信息受限时动态俯仰角感知显著大于地面,而静态俯仰角感知则大大降低;这种地月差异在加入视觉信息后大幅度减少.揭示了月面与地面驾驶运动感知特性的差异,为月球车驾驶运动模拟策略的优化提供了依据.
Abstract
The training of lunar rover driving skills for astronauts requires the simulation of realistic motion perception characteristics.The key lies in understanding the differences of driving motion perception between ground and moon.A high-fidelity simulation scene was created to compare the driving characteristics of a lunar rover on the moon and on Earth.Additionally,a software framework based on spatial orientation model was developed to simulate and compare the differences in forward motion perception between lunar and ground driving.The results indicate that under lunar conditions the lunar rover experiences reduced acceleration changes and slower acceleration and deceleration,which increases the displacement of sideslip.Additionally,limited visual information leads to a significantly larger dynamic pitch angle perception compared to ground conditions,while static pitch angle perception is greatly reduced.However,this difference could be greatly reduced when visual information is available.The differences in motion perception characteristics were revealed between lunar and ground driving rover,providing a basis for optimizing lunar rover driving motion simulation strategies.
