|
Abstract:
动态飞行模拟器是一种以离心机作为运动平台的持续过载模拟设备, 其运动规划直接影响过载模拟精度。该文主要针对动态飞行模拟器实时运动规划问题进行研究, 建立了过载模拟模型, 分析了卸载段动态飞行模拟器运动参数无法计算的原因, 在此基础上提出了基于2维插值法的实时运动规划算法, 解决了动态飞行模拟器实时运动规划问题。为了验证算法的准确性, 分别针对纯z向梯形过载曲线和3轴过载曲线进行模拟仿真, 分析算法对过载模拟误差的影响。仿真结果表明: 模拟过载能较好地跟踪理论过载, 算法具有较好的准确性和实用性。
Abstract：Dynamic flight simulators (DFS) use a centrifuge to simulate sustained G-loads. The motion planning for the DFS directly affects the accuracy of the G-load simulations. This paper describes a real-time motion planning algorithm for a flight simulator. The G-load simulation model is given but is difficult to solve when the G-loads are negative. A real-time motion planning algorithm with two-dimensional interpolation is used to generate both a trapezoidal G-load curve and three-axis G-load commands. The simulation results show that the simulated G-loads precisely track the commands. The algorithm is accurate and practical.
