基于LS-DYNA的Lagrange网格与SPH鸟撞分析对比研究
说明: 别采用La酽蚰ge网格和SPH(SmoothedPalticleHyd功dyn啪ics,光滑粒子流体动力学法)模拟鸟体
进行风挡抗鸟撞性能对比分析,表明SPH分析得出的结果与传统的h鲫ge网格方法得出的结果以及试验实测
结果基本一致,为分析动力学大变形问题提供了更多的途径。(The results are basically consistent, which provides more ways for the analysis of dynamic large deformation problems.)

基于模糊PI控制的PWM整流器设计
说明: 针对双闭环矢量控制的三相电压型 PW M 整流器难以用准确的数学模型描述、以及通过其简化的数学模型求得的
P I参数需要实验整定的问题 ,提出了基于模糊 P I控制器的新型智能化控制方法。与传统的 P l控制方法相比。该方法不
仅实现了 PI参数的自整定。还使系统具有更好的响应性能、更高的稳定性及鲁棒性。利用 M atlab/Sim ulink 工具箱建立
了基于模糊 P l控制器的整流器仿真模型,并通过仿真实例对此设计方法进行了实验验证。(It is difficult to describe the three-phase voltage type PWM rectifier with double closed-loop vector control by accurate mathematical model and to obtain it by its simplified mathematical model
For the problem that PI parameters need to be adjusted by experiment, a new intelligent control method based on Fuzzy PI controller is proposed. Compared with the traditional PL control method. This method does not
Only the self-tuning of PI parameters is realized. It also makes the system have better response performance, higher stability and robustness. Using Matlab / SIM ULINK toolbox to build
The simulation model of rectifier based on Fuzzy PL controller is presented, and the design method is verified by simulation example)
