动力学环境下液浮积分陀螺仪误差建模与仿真

Error Modeling and Simulation of the Liquid Floated Integral Gyro in Dynamical Environment

分析了动力学环境下液浮积分陀螺仪的工作原理和误差情况.提出一种反映液浮积分陀螺仪结构振动特性的误差模型,对过载振动复合环境下液浮积分陀螺仪测量误差进行仿真,得到复合环境下液浮积分陀螺仪测量误差的规律.研究表明,在过载振动复合环境下,液浮积分陀螺仪因为结构变化而产生了较大的工作误差,这些误差的表现形式相当复杂,在单一环境实验中是无法体现的.

The error of the liquid floated integral gyro is analyzed in dynamical environment.and a model of error of the Liquid Floated Integral gyro reflecting the vibration characteristics of the structure is presented.The simulation of oper- ation process of the Liquid Floated Integral gyro in overloading and vibration compound environment(OAVCE)has been done,and the characteristics of the crror oi the Liquid Floated Integral gyro in OAVCE are obtained,It is shown in research that because of the structural change of the liquid floated integral gyro in OAVCE,there is more severe error which can not be found in single environment test.
