利用CFD软件，采用雷诺应力模型分别计算了300型和250型水力旋流除砂器的内流 场，得到了2种水力旋流除砂器的轴向、径向、切向速度及压强的分布曲线。通过对所得结果的 分析，发现模拟结果基本符合旋流除砂器的运行规律。比较2种旋流除砂器的内流场，表明改进 的300型水力旋流除砂器的结构及分离能力优于原来250型水力旋流除砂器，为水力旋流除砂器 的优化设计和选型提供了可靠的设计依据。(use CFD software, Reynolds stress model used to calculate the respective 300-and 250-type sander hydrocyclones the flow field, been two kinds of hydrocyclones sander axial, radial and tangential velocity and pressure in the distribution curve. Based on the results of the analysis, the simulation results are consistent with the Cyclone sander operating rules. Comparing two kinds of Cyclone sander within the flow field, show improved 300 Desanding Hydrocyclones the structure and separation capacity than the original 250-hydrocyclone sander, Desanding Hydrocyclones for the optimum design and selection provided a reliable basis for the design.)

power_switching_power_supply_lib.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_switching_power_supply_lib.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

该计算程序可以对无固定约束碰撞振动系统在激励力作用 下的系统响应进行计算，模拟系统动态响应，并自动判断颤振发生情 况，记录不同参数组合（阻尼比，质量比，恢复系数，间隙，频率比） 情况下系统的响应数据，输出发生颤振的参数组合数据。(The program can be used to study the impact force of a vibro impact system with no fixed constraint The system response is calculated, the dynamic response of the system is simulated, and the occurrence of chatter is judged automatically Different parameter combinations (damping ratio, mass ratio, recovery coefficient, clearance, frequency ratio) were recorded In the case of the system response data, the output parameters of flutter data are output.)

应用最小二乘法对二阶系统进行辨识，得到相关参数(Application of least squares, second order system identification, are relevant parameters)
