Based on test data from the hot forge experiments on Gleeble 1500, a Kumar type constitutive equation for 33Mn2V steel is established. Applying this constitutive equation in commercial FEM software of MSC/SuperForm 2005, the piercing process of 33Mn2V steel in Mannesmann mill is then simulated. The modeling results visualized the dynamic evolution of equivalent stress, especially inside the workpieee. It is shown that the non-uniform distribu- tion of stress on the internal and external surface of the workpiece is a distinct characteristic of processing tube pierc- ing. The numerical model was verified by comparing the values of calculated force parameters of the piercing process with those measured in laboratory eonditions. And it shows that the Kumar-type constitutive relationship meets the practical needs.

In order to reflect the stochastic characteristics of structures more comprehensively and accurately, a theory and method for modeling of structures with stochastic parameters is presented by using probability finite element method and stochastic experiment data of structures based on the modeling of structures with deterministic parameters. Double-decker space frame is taken as an example to validate this theory and method, good results are gained.

针对声源目标因运动突变而产生的跟踪精度降低的问题,提出了一种基于压缩映射改进的粒子滤波声源跟踪方法。首先利用瑞利分布对加速度信息进行修正,并将其引入到目标运动模型中以增强声源信息的维度;其次将采样粒子集压缩映射到目标运动界限范围内,从而提高声源目标估计的准确性;最后引入退火因子改善粒子集因压缩映射带来的样本匮乏问题。实验结果证明方法不仅在一般的声源运动中同样效果较好而且适应于突变运动,具有一定的鲁棒性。
