Abstract：Experimental support resonance method is used to measure Young's modulus experiment device, and material separation variable method is used to approximate solution Housner transverse vibration equation of tubular material containing fluid tube material which can obtain the liquid density calculation formula. Through the experimental measurement and calculation of the density of distilled water and different concentrations of sucrose solution values, the relative error between the experimental value with the theoretical value is in the normal range of error of being less than 3%,which provides a new method to measure the liquid density.
