CAE software development and engineering application of explosive welding

为了有效控制爆炸焊接金属复合板的质量,应用C++和OpenGL研制开发了爆炸焊接CAE软件系统EWCAE(Explosive Welding Computer Aided Engineering),将理论计算、数值模拟与爆炸焊接实验相结合,确定爆炸焊接窗口范围以及合理的爆炸焊接工艺参数。通过对爆炸焊接数值计算方法和CAE工程分析软件的研制开发以及该软件在爆炸焊接工程实际应用的介绍,了解该软件系统可以实现金属爆炸焊接窗口计算与曲线绘制、复板飞行姿态计算和爆炸焊接三维动态数值模拟。基于CAE工程分析软件来辅助爆炸焊接生产工艺的制定,不仅使爆炸焊接金属复合板的质量得到有效控制,还对于个性化、差异化和精细化爆炸焊接技术开发具有重要意义,从而实现技术研发与生产加工的数字化、标准化和规范化。因此,计算机仿真和数值计算也是爆炸焊接重要的研究手段。

In order to effectively control the quality of metal clad plate with explosive welding,EWCAE(Explosive Welding Computer Aided Engineering)was developed by application of C++and OpenGL.Explosive welding window and reasonable technology parameters could be determined by the combination of numerical simulation,theoretical calculation and experiments.Through numerical calculation,analysis and applied introduction of the CAE software,the programing tool can realize calculation of the explosive welding window,curve drawing,flight attitude of the flyer plate and three-dimensional simulation of explosion welding.Based on the application of the CAE software,not only quality of metal clad plate can be effectively controlled,but also it is great significance for the personalized development and sophisticated technology of the explosive welding.Digitalization and standardization of technology research and development and production for explosive welding can be realized.Therefore,computer simulation and numerical calculation are also an important research method for explosive welding.
