abaqus经纬编织织物模型，umat子程序(ABAQUS warp and weft knitted fabric model, UMAT subroutine)

说明：  该模型是对50kW、380V、50Hz三相三电平逆变器的两个相同电路进行建模。IGBT逆变器采用SPWM技术，(8kHz载频)将直流电源从a +/-200Vdc源转换为220V AC, 50Hz。逆变器通过75kVA 220/380V变压器输入50kW电阻负载。变频器输出采用L-C滤波器滤除主要产生于8kHz开关频率倍数(Fh=n*8000 +/-k*50Hz)附近的谐波频率Fh。逆变器所需的12个逆变脉冲由PWM发生器块产生。该系统以恒定的调制指标在开环中工作。 电路1使用三电平桥块对逆变器进行建模。电路2使用独立的IGBTs和二极管块。用开/关延时块模拟死区，仅在电路1上应用。(It is easy for us)

ansys计算边裂纹断裂参数应力强度因子和J积分还有G释放率(ansys fracture K J G)

说明：  混响器的MATLAB实现：利用MATLAB/SIMULINK软件实现混响器(Realization of reverberator with MATLAB)

多目标优化的最大妥协解，转换成单目标优化 三人博弈的部分(The maximum compromise solution of multiobjective optimization)

说明：  400KW光伏参与并网，4组光伏模组共同输出400KW的功率(400KW photovoltaic participates in grid connection, 4 sets of photovoltaic modules jointly output 400KW power)

包括GPS仿真的全套代码，matlab和C#。GPS信号的模拟、捕获、追踪，以及数据的处理，极限的解算，周跳的探测及整周模糊度的接算。有用的资料与大家共享后才能体现其价值，希望同仁们也能及时共享比较好的资料，大家一同探讨、进步。(ncludes a full set of GPS simulation code, matlab and C#. GPS signal simulation, capture, tracking, and data processing, limit solution, cycle slip detection and integer ambiguity. Only when useful information is shared with all of you can it reflect its value. We hope that colleagues can also share better information in time, and everyone will discuss and progress together.)

说明：  该插件用于快速生成2维VORONOI图 请将文件解压到C盘-用户-abaqus_plugins文件夹下(This plug-in is used to generate 2D Voronoi graph quickly Please unzip the file to the C disk user ABAQUS plugins folder)

说明：  利用MATLAB实现平行泊车过程演示，实现泊车动画演示。(MATLAB parallel parking process demonstration.)

纳入了机械损伤和应变速率的断裂UMAT子程序，不能用于平面应力。(The fracture UMAT subroutine incorporating mechanical damage and strain rate can not be used for plane stress.)
