两个关于ansys的应力与应变方面的详细实例分析，容易入门与操作(Two stress and strain on the aspects of detailed case studies on ansys, easy entry and operation)

包含三个M文件，程序为本人自行编译完成，Demo中设有仿真信号验证，并经本人实际齿轮箱信号（轴承外圈故障）测试，经包络分析结果显示能够有效定位轴承外圈故障频率。 亲测可用。(It contains three M files. The program is compiled and completed by myself. Demo has simulation signal validation. It has been tested by my actual gear box signal (bearing outer ring fault). The envelope analysis results show that it can effectively locate the bearing outer ring fault frequency. The pro-test is available.)

说明：  将三相电流实施坐标变换后得到了M-T坐标系下的电流反馈值，再经过PID调节后，形成了电流闭环控制；且定子电流通过反变换后得到静止两相坐标系的定子电压给定值，再经过SVPWM控制逆变器，得以输出三相电压(The feedback value of the current in the M-T coordinate system is obtained after the coordinate transformation of the three-phase current. After PID adjustment, the current closed-loop control is formed.The stator current is inversely transformed to obtain the stator voltage value of the static two-phase coordinate system, and then the three-phase voltage can be output by the SVPWM controlled inverter)

html5 canvas饼图统计图表效果，配合jquery实现的，鼠标悬停于图上时会动态突出显示的饼形图。圆饼图和右侧的列表数据是对应的，用鼠标点击右侧的选项，左侧饼形图的对应部分会向外突出显示，这样便于清楚的看出所选择数据的比重，在百度统计中，会看到类似的效果。
