摘要
叙述了飞机蒙皮拉形有限元模拟技术所涉及的有限元数学模型、接触摩擦模型和卸载回弹模型 ,建立了有限元计算模型 ,开发了数值模拟软件 ,通过有限元算例与试验结果的对比 。
In this paper, the finite element mathemetical model, contact friction model and unloading spring back model involved in the finite element simulation of the stretch forming of aircraft skin are described. The finite element calculation model is established and the numerical simulation software is developed. The reliability and calculation accuracy of the finite element calculation model and the software are verified by means of the comparison of the finite element calculation examples and the test results.
