스프링-質量 系에서 磁性流體의 振動 特性에 關한 實驗的 硏究 = An Experimental Study on Vibration Characteristics of Magneticfluid in a Spring-Mass System

다국어 초록 (Multilingual Abstract)

Distilled water, oil and magneticfluid in this study were used to know the vibration characteristics that each kind of fluids in spring-mass system transfers momentum.
The spring-mass system with hydraulic fluid showed frequency with maximum amplitude. In case the diameter of inner cylinder or hydraulic fluid is changed, as the change of diameter of inner cylinder or hydraulic fluid affected to the spring-mass system and brought about changing of natural frequency of system, a domain of frequency is a little changed. The vibration characteristics of distilled water in spring-mass system show that resonance properties happened sharply when the diameter of inner cylinder is relatively small. The higher viscosity in spring-mass system is the effect of mechanical vibration decreases and viscosity dominates it. In the spring-mass system, in case of magneticfluid under magnetism, when the diameter of inner cylinder is relatively big, the changing value of output amplitude is small.
