基于转动惯量的刚体9个惯性参数的测量
The Measurement of Nine Inertial Parameters of Rigid Body Based on the Moment of Inertia
摘要
Abstract
For three-dimensional space, a new method which can measure the nine inertial parameters of a rigid body simultaneously is proposed. With the law of motion that when aerostatic bearing move slowly its angular velocity is a single exponential function decayed with time, the moment of inertia of the rigid body rotating a axis in an arbitrary direction is obtained, through nine measurements, the inertial parameters of a rigid body can be got finally. A set of instrument used for measuring the rigid body inertial parameters is designed. This instrument can measure the nine inertial parameters of a rigid body in three-dimensional space simultaneously. There' s no need to re-assembly in the process of measurement, so intermediate testing quantity, error made by human and measuring time are all reduced.关键词
