用有限元分析软件ansys来仿真模拟火车过桥的过程中桥的受力分析(The deformation of high-speed railway track was simulated by ansys)

说明：  非常详细的基于stm32的ATT7022驱动程序！除了读取各个计量参数外还包含电压、电流、功率以及相位角的校正和温度系数补偿。该程序是本人参考官方手册所写且经过实际测试已用于项目中，里面每个函数都有详细的注释，对新手具有很大的参考价值(Very detailed STM32 based ATT7022 driver! In addition to reading each measurement parameter, it also includes voltage, current, power and phase angle correction and temperature coefficient compensation. This program is written by myself with reference to the official manual and has been used in the project after actual test. Each function in it has detailed comments, which is of great reference value to novices)
