EXPERIMENT METHOD AND GRASP OF DYNAMIC PROPERTIES OF VISCOUS FLUID MATERIAL

Study on strain, temperature and frequency sensitives dependence of shearing type viscous fluid damper Part1

Abstract

It is necessary to clarify the characteristics of the ideal viscous fluid material to examine a characteristic model of the viscous fluid damper of the various shapes. Here the small size testing equipment was used in consideration of the steel stiffness, the work efficiency and so on. But the correct grasp of the characteristic from the measured values with that equipment was difficult, because these values were not the ideal forces and were affected by the scale effect. Therefore, inspecting those unexpected forces and grasping the ideal values are important. First of all, part1 shows the method to consider properties of viscous fluid material under ideal condition with experiment and analysis, and the test outcomes performed in extensive strain, temperature and frequency.
