中文摘要:
      目的 探索一类飞行器动态变化加速度模拟试验原理。方法 建立三轴动态变化加速度模拟系统的数学模型, 研究试件上某一特定位置的目标加速度与离心机及动量矩框架的输入角速度、 角加速度以及旋转角度之间的关系, 利用已知的目标加速度反解方程得到输入角速度、 角加速度以及旋转角度。结果 使用Matlab进行方程求解和仿真模拟, 仿真结果与目标加速度一致。结论 仿真结果表明, 通过反解方程进行动态加速度模拟试验是可行的。
英文摘要:
      Objective To study simulation test principle of a type of aircrafts with variable accelerations. Methods In this paper, a mathematical model of simulation system with three-axial variable accelerations was presented. The equations between objective acceleration on a point of test product and input angular velocity, angular acceleration of centrifugal and rotation angle of momentum frames were derived. Based on the known objective acceleration on a point of test product, input angular velocity, angular acceleration of centrifugal and rotation angle of momentum frame were obtained via inversing equations. Results Solutions and simulation were completed by MATLAB,the results were consistent with objective acceleration. Conclusion The result indicated that inversing equation was feasible.
