飞行器质量特性参数测量
A new measurement method for mass property parameters
摘要
Abstract
Mass property parameters（mass,center of mass,moment of inertia） are important technology parameters of aircraft.The traditional mass and center of mass measurement uses centroid units,and the moment of inertia measurement torsion units,which can only get results in installing direction.Because of the structural reasons,there is a need to get all high accurate physical parameters in clamping once.To solve this problem,this study merges centroid units and torsion units into one composite unit,installs a table which can tilt and rotation to measure the moment of inertia in different conditions.The moment of inertia and product of inertia relative to three axis are calculated by the method of coordinate transformation.Measurement theory of mass,center of mass and mass moment of inertia are described,the main reason of causing measurement errors is discussed,and the measurement accuracy affected by tilt error is analyzed.关键词
