代码说明:

  本文介绍的是一种改进的SPIHT算法,是基于图像编码的小波系数块的,它主要是把四个系数分成一个块,与阈值比较,分出重要与非重要,在进行编码。(This article is a modified SPIHT algorithm is based on the wavelet coefficients of image coding block, it is mainly divided into the four coefficients of a block, compared with the threshold value, separate the important and non important, during the encoding.)

  • 风力机结构耦合振动分析
    说明:  采用通用动态尾流理论进行风力机气动力学的计算分析,并用 MATLAB/Simulink进行编 程,建立了风力机传动链的数学模型。 在 MATLAB/Simulink中进行传动链系统的编程运算,建立了 风力机 ADAMS柔性多体结构动力学仿真模型,并利用 MATLAB/Simulink和 ADAMS进行风力机振 动性能的联合仿真。 仿真时将气动载荷加载到风力机叶片结构上,将传动系统模型的反扭矩加到 AD AMS风轮模型上,同时考虑风力机的结构变形对气动性能、传动性能产生的影响。 仿真最终实现了风 力机系统振动性能耦合分析,其数据同实验测试数据比较表明,该联合仿真方法可以较好地模拟风力机 的振动特性。(TheaerodynamicscharacteristicsofwindturbinewerecalculatedbyapplyingGDWthe oryandwereprogrammedin MATLAB/Simulink.
