航空重力仪减振系统振动研究

航空重力减振系统是有效减弱机载环境下高频振动的主要途径,从而提高航空重力的测量精度。因此,设计减振系统的首要问题是设定其合理的刚度、阻尼和质量等重要的特性参数。笔者通过建立航空重力仪两种减振系统类型运动微分方程,经过理论和实例探讨了减振系统模型,旨在深入了解航空重力减振系统的减振规律,为其特性参数设计提供理论依据。

A study of the vibration for the airborne gravimeter vibration reduction system

The airborne gravity vibration reduction system is an effective way to attenuate high frequency vibration in the airborne envi?ronment,thus improving measurement accuracy of aviation gravity.Therefore,the primary problem in the design of the vibration reduction system is to set up such important parameters as reasonable stiffness,damping,and quality.The authors established differential equations of motion for two types of vibration reduction system of airborne gravimeter.With theoretical and investigate instances,the authors dis?cussed vibration reduction system model,with the purpose of in-depth understanding of the law of airborne gravity vibration reduction system and providing the necessary theoretical support for its parameter design.
