门式起重机箱形梁结构的断裂评定系统开发

Development of fracture evaluation system for box girder structure of gantry crane

研究门式起重机箱形梁结构断裂评定的方法,以Qt为开发框架,实现此方法的GUI模式。通过XML的数据传输与存储,实现系统对Ansys的调用,使评定过程轻松化,流程简单化。研究了调用Ansys的接口处理方法,改善数据传递引起的误差,使用QCustomplot绘制失效评定曲线和评定点。实地测量表面裂纹缺陷,输入规则化的裂纹参数以及设置相应的评定参数,便能够得到直观的失效评定(FAD)图和一份详细的结果报告。对系统后续的扩展和实际运用具有一定的参考意义。

This paper studies the method for evaluating the structural fracture of the box girder of gantry cranes.The GUI mode of this method is realized by using Qt as the development framework.Through XML data transmission and storage,the system can use Ansys to make the evaluation process easier and the process simpler.The interface processing method of using Ansys is studied to improve the error caused by data transmission,and QCustomplot is used to draw failure evaluation curves and evaluation points.An intuitive failure assessment diagram(FAD)and a detailed result report are obtained by conducting the measurement of surface crack defects on the spot,inputting regular crack parameters and setting corresponding evaluation parameters.This paper can serve as a reference for the future expansion and application of the system.
