红外无损检测的三维有限元仿真

3-D Finite Element Method Simulation of Infrared Non-destructive Testing

以混凝土构件内部孔洞检测为研究对象,在ANSYS9.0平台上采用有限元方法对其进行三维仿真,研究在一定激励强度下激励时间对红外无损检测结果的影响,从而确定红外无损检测的最佳检测时机,有效地缩短红外热像仪的使用时间,延长其使用寿命。

Tries to find the optimum detection time for the detection of inner hole in concrete by infrared thermography, It takes the finite element analysis （FEA） software ANSYS as the simulating tool, studies the influence of stimulating time with the same stimulating strength. Thus infrared thermography can be reduced using time and lengthened its usage period effectively.
