摘要
在显式积分有限元分析软件Ls-Dyna平台上进行了薄壁管件的准静态压溃模拟计算.为了减少计算时间,采取了提高准静态加载速度的方法.通过对薄壁管件在不同加载速度下计算结果的分析比较,给出了确定加载速度提高范围的原则.最后,对提高加载速度的方法与Ls-Dyna中的MassScaling方法进行了比较.
Quasi-static collapse simulations of thin-wall-tubes are performed with Ls-Dyna code. To reduce the computational time, the speed of quasi-static loading is increased. Studies are conducted with different loading speeds. A range of the load speed used for the simulation is specified. This method is compared with Mass Scaling method integrated into Ls-Dyna.
