Simulation of APDL-Based Super-High Pressure Compressor Pipeline System Vibration Control

In order to solve the problem that super-high pressure compressor pipeline system had serious vibration and noise pollution, finite element method was used in this paper to have system vibration analysis and a vibration control program was designed by changing system inflexibility. On the other hand, in order to improve the efficiency of simulation modeling, the ANSYS parametric design language (APDL)was used to build pipeline system vibration analysis models which can be revised by test data and recover vibration field. After the implementation of the program, test data showed that the vibration displacement drop greatly, all displacement values meet compressor vibration norms. The result proved that the APDL-based finite element analysis approach was an effective way to have super-high pressure compressor pipeline system vibration control, which solved hand-modeling inefficiency issues and improved the efficiency of the simulation modeling.
