Effect of fixing style on dynamic characteristic of water jet air ejector

This paper calculates the natural frequencies and the vibration modes of the former six harmonics based on FE analysis.Meanwhile,the effect of the fixing style on the dynamic characteristics of the water jet air ejector is also studied.The result shows that the fixing style will both affect the natural frequencies and the vibration modes.The more tight effects the fixing style has,the larger value the ejector will have for the natural frequency.However,there is not a necessary relation between the vibration mode and the fixing style.No matter what kind of fixing style,as the number of the harmonic increases,the vibration mode will be more complex.
