摘要
为满足某型号大尺寸飞行器航向转动惯量测量的实际需求,提出了一种基于复合扭摆运动的飞行器转动惯量测量方法。解算了复合扭摆运动微分方程,给出了存在质心偏距和初始偏角情况下的扭摆曲线,为复合扭摆法测产品转动惯量的误差补偿提供了理论依据。分析表明,基于复合扭摆运动的转动惯量测试方法具有一定的工程应用价值。
In order to satisfy the need for measuring the moment inertia of course dirction for large dimension aircrafts,a method for measuring the moment of inertia based on the composite torsion pendulum movement was put forward.The numerical solutions for differential equations and the pendulum curves were obtained when centroid departure and initial departure angle exist,which can serve as the theoretical basis for compensation of measurement errors.Analysis shows that this method for measuring the moment of inertia has certain engineering application value.
