摘要
为了评估炸药在地下结构附近或地下爆炸时产生的地冲击对结构的威胁和影响,进行爆炸环境下的地运动测量,可以为工程安全及其防护设计提供合理有效的数据和依据。采用改进型差动变压式位移传感器(LVDT)对其进行测量。该LVDT具有行程大,精度高,稳定性好,安装方便等优点。需要解决的两个关键技术是:测试原理的合理解释、传感器的抗冲击能力和传感器不同与常规应用的安装技术。介绍了利用LVDT位移传感器测量地运动的原理、方法以及实验技术。实验表明了该技术可行、有效。
In order to evaluate the influence on the structure of ground motion resulted from ex plosion, it is important to measure the display of ground motion, because it can provide reasonable and effective data for safe engineering and prevention design. A modified LVDT display sensor can be used for explosion ground motion measurement. The novel LVDT has the advantages of long range, high precision, high reliability and easy setting. There are two key technologies still to be solved, such as reasonable interpretation for measurement principle and high capacity of anti high shock overload of LVDT sensor and its field engineering. The measurement principle and practical experimental techniques were introduced. The practical results indicate that the modified LVDT sensors are feasible and effective.
