This paper introduces a new method for the use of tensor-resistive sensors in large spherical storage tank equipment (over 12,000-mm diameters). We did an experiment with 19 petroleum or ammonia product sphere-shaped storage tanks with volumes of 1000 and 1800 cubic meters, respectively. The existing literature only contains experiments based on sensors for tanks with diameters no larger than 600 mm. Based on a number of resistive strain sensor measurements on large spherical pressurized vessels regarding structural integrity assessment, the present paper is focused on the comparison between "real-life" obtained sensor data versus finite element method (FEM) simulation results. The present paper is structured in three parts and examines innovative directions: the use of the classic tensor-resistive sensors in a new approach concerning large structural equipment; an original 3D modeling method with the help of the FEM; and conclusions with possible implications on the regulations, design, or maintenance as a result of the attempt of mutual validation of the new methods previously mentioned.

新型电阻应变传感器方法在有关大型球形储罐结构在其使用寿命和压力测试过程中的行为的实验和理论研究中的使用。

本文介绍了一种在大型球形储罐设备(直径超过12,000 mm)中使用张量电阻传感器的新方法。我们用19个分别容积为1000和1800立方米的石油或氨产品球形储罐进行了实验。现有文献仅包含基于传感器的直径不大于600毫米的储罐的实验。基于有关结构完整性评估的大型球形压力容器的许多电阻应变传感器测量结果,本论文着重于“实际”获得的传感器数据与有限元方法(FEM)仿真结果之间的比较。本文分为三个部分,探讨了创新方向:在涉及大型结构设备的新方法中使用经典的张量电阻传感器;借助FEM的原始3D建模方法;尝试相互验证前面提到的新方法的结果可能对法规,设计或维护产生影响的结论。
