摘要

平台式绝对重力仪在测量过程中受振动干扰的影响较大,主要采用振动补偿的方法处理振动干扰,提高测量精度。基于自主研制的激光干涉式绝对重力仪搭建了一套模拟车载平台绝对重力测量系统,利用基于系数搜索的振动补偿方法来减小振动干扰对重力测量的影响,在三种不同地面环境进行试验并对振动情况进行了评估。试验结果表明,经过振动补偿,室内地面环境重力值标准差减小83%,室外方砖地面环境重力值标准差减小41%,室外柏油地面环境重力值标准差减小60%,三种工况下重力值测量准确度均优于2 mGal。基于系数搜索的振动补偿方法可为平台式绝对重力仪的重力测量提供参考。

Abstract

The platform-type absolute gravimeter is greatly affected by vibration interference during the measurement process. The vibration correction method is mainly used to deal with the vibration interference and improve the measurement accuracy. Based on the self-developed laser interferometric absolute gravimeter, an absolute gravity measurement system simulating a vehicle-mounted platform was built. The vibration correction method based on coefficient search was used to reduce the influence of vibration interference on the gravity measurement in this system. The experiments were carried out on three different ground environments and the vibration conditions were assessed. Experimental results show that the standard deviation of the gravity value in an indoor ground environment, an outdoor square brick ground environment, and an outdoor asphalt ground environment can be reduced by 83%, 41%, and 60% respectively. In these cases, the measurement accuracy of gravity value is better than 2 mGal. The vibration correction method based on coefficient search can provide reference for the gravity measurement of the platform-type absolute gravimeter.
