分析了某钢厂5000mm精轧机立辊液压回油管振动问题,考虑使用改变管路的刚度来解决振动问题,并使用ANSYS CFX软件对这段液压回油管路的一截进行了分析,进行了现场测试,通过仿真和测试共同验证改变管路刚度可以有效地减少回油管振动。
The vibration problem of vertical hydraulic return pipe of 5000mm finishing mill of a steel mill was analyzed. The vibration problem was solved by changing the stiffness of the pipeline. A section of the hydraulic return pipe was analyzed by ANSYS CFX software. Test, through the verification of simulation and testing together to change the pipe stiffness can effectively reduce the return pipe vibration.
