一种测量土工布撕破试验力的传感器

传感器的形式很多,应用于各个领域。S型传感器应用比较广泛,而市场上的传感器价格普遍较高,如何降低成本,又能保证实用、精美,是值得讨论的问题。文中从应变电测方法角度设计和制作了一种S型的400N拉压力传感器,可用于测量土工布撕破强力的大小,并对其进行标定、应用检验及有限元分析。结果表明设计的力传感器具有灵敏度高、稳定性好、结构紧凑等优点,从而为土工布的工程应用提供了必要的试验依据。

Design of a Force Sensor for Measuring the Tearing Force of Geotextiles

With its various types,sensor is used in many areas.. One of the most widely used types is s-type sensor,which is rather expensive now. Therefore,the question how to get an inexpensive and fine sensor be comes a major concern.. A tensile and compressive force s-type sensor of 400N is designed and produced with the use of electrical strain testing. Then demarcating,checkout and analyzing by finite element the sensor .by using the force sensor to measure the tearing force of geotextiles have all shown that the force sensor has functioned excellentlyin higher sensitivity and higher stability and compact structure, providing the necessary experimental data for the geotextile application.
