本文对动态孔隙水压力传感器的设计问题进行了专门研究。内容包括:(a)根据泊稷叶公式建立了滤水系统的动态特性模型;(b)由该模型对典型被测压力信号的响应误差提出了设计判据;(c)孔隙水压力传感器的设计与制作;(d)在激波压力作用下,模型的理论响应与传感器的实测响应作了检验对比。此外,还简单介绍了传感器在现场的应用情况。
This paper focuses on the design of dynamic pore water pressure sensors. The contents include: (a) The dynamic characteristics model of the water filtration system was established based on the Poisson’s leaf formula; (b) The design criterion was proposed by the model for the response error of the typical measured pressure signal; (c) The pore water pressure sensor Design and production; (d) Under the shock pressure, the model’s theoretical response is compared with the sensor’s measured response. In addition, the application of sensors in the field is briefly described.
