摘要
传统的LNG运输过程中难以准确监测汽车LNG罐的储液状态。提出一种监测LNG罐静态储液状态的方法,通过模态分析软件,得到测试系统的振动频率与储液质量之间的关系,并通过试验验证该方法的准确性,可以有效地监测罐体中的储液质量。
In the traditional LNG transportation process,it is difficult to monitor the liquid storage state of LNG tank accurately.This paper presents a method for monitoring LNG static state of the liquid storage tank,through the modal analysis software,obtains the relationship between the vibration frequency and the liquid storage level.This method can be used to accurately monitor the storage level of the liquid tank.
