某特种机械开孔减振技术的仿真研究

Simulation study on vibration reduction with open pore for a special machine

利用空气动力学理论建立数学仿真模型,采用Matlab软件编写程序得到某特种机械导气室气体压力随时间的变化曲线。探讨导气室内部开孔孔径大小对于此种机械导气室压力以及气孔反作用力的影响,为特种机械振动控制以及精确度的提高提供有益参考。

In this paper,a mathematical simulation model was established based on aerodynamics theory,and the change curve of the gas pressure in the air chamber of a special machine was obtained by programming with MATLAB.The influence of the diameter of the open pore in the air chamber on the pressure and the reacting force of the air chamber was discussed.This paper has provided a useful reference for the vibration control of the special machine and the improvement of its accuracy.
