- Abstract
The piezoelectric micro-jet is a multi-physics coupling device which contains electro-mechanical coupling, fluid-structure coupling and gas-liquid two phase flow coupling. The fluid-structure coupling is mainly referring to the coupling effect between the piezoelectric vibrator and the fluid. Generally, the working frequency of the micro-jet is the resonant frequency of the vibrator which is affected by the fluid-structure coupling. The fluid-structure coupling effect of a kind of micro-jet, which is used for the bearing lubrication, is analyzed in this paper. The added mass is created on the piezoelectric vibrator due to the strong fluid-structure coupling effect, as the vibrator of the micro-jet is immersed in the lubricating oil. The added mass of the piezoelectric vibrator, which directly influences the resonance frequency, is studied in this paper. The relationships between the influence factors and impact strength of the added mass are analyzed and the method of reducing the effect of additional mass is presented. In addition, the adjustment scheme of the working frequency of the micro-jet by taking advantage of the additional mass effect is given.
