By analyzing the finite element parameters of floating-roof tapered tanks under harmonic settlement,the effects of the major geometric parameters of tapered tank(including wall variable parameters,wind girder stiffness,radius-to-thickness ratio and height-to-radius ratio) on tank structure deformation and stress are d.

Defects inspection system for tank floors based on virtual instrument technique;

According to the current problems existing in the magnetic flux leakage testing for tank floor,a mobile robot was developed which could take the place of manual or power-driven approach to tank floor MFL inspection.

In order to improve the efficiency of magnetic flux leakage(MFL) testing for tank floors,the flaw location,test data description and visualization from anomalistic signals are studied.

Based on the magnetic flux leakage(MFL) technique,a magnetic flux leakage testing instrument for corrosion in the tank floor plate driven by electric motor is developed.
