摘要
针对某一型号蒙拉机,基于UG建模并进行运动仿真。结合有限元仿真软件,研究了蒙拉机运动参数与有限元仿真边界条件之间的转换算法。对ABAQUS进行了二次开发,直接把机器工作时运动轨迹参数生成有限元仿真边界条件。通过对蒙皮拉形工艺的有限元仿真,验证了系统的准确性,为有限元仿真技术在实际生产中的应用提供了参考。
Aiming at a certain type of skin stretch forming machine, 3D digital model built based on UG and motion simulation is exercised. Transformation algorithm between mechanism motion parameters and boundary conditions of FEA is researched combining with the finite element simulation software, after the adaptable development in ABSQUS, parameters of the machine trajectory, which are generated by machine operation, and directly translated into boundary conditions of the finite element simulation. The simulation results of the skin stretch forming process prove the validation of the system, and it is beneficial to the application of the finite element simulation technology in industry.
