Experimental study on measuring liquid viscosity by vertical oscillation of fusiform wing body
摘要
Abstract
In order to measure liquid viscosity quickly, the relations between the liquid viscosity and the logarithm damping rate of maximum vibration speed in all cycles were studied when the fusiform wing body spring oscillator vibrates vertically in liquid. The viscosity coefficient calculating formula of spring oscillator method was derived. The conformation of the liquid viscosity measuring system based on the fusiform wing body spring oscillator and the method of how to acquire the oscillating signal were also discussed, and some liquid viscosity measuring tests were also conducted with this system. The formula shows that the liquid viscosity can be calculated fast by taking the average value of logarithm damping rate of maximum speed as a characteristic parameter, and thus, theoretical basis of spring oscillator method for measuring viscosity is founded. Spring oscillator method can be applied to test the viscosity of room temperature liquid. The new method has many advantages, such as convenient for use, simple for installation, low for cost, and convincable for measurement and easy for continuous testing, and so on.关键词
