Abstract

Based on deflection phenomenon of force-displacement curve and phase lag phenomenon of time history curve of a double-outbar pore type viscous damper, the mathematical model for velocity-load characteristics of the viscous damper was established considering shear thinning characteristics and compressibility of dimethyl silicone oil.The mechanical characteristics of the viscous damper under sinusoidal displacement excitation signal were simulated using the software MATLAB Simulink.The results showed that the output damping force of the viscous damper is directly determined by the shear thinning characteristics of dimethyl silicone oil; the compressibility is the main reason for deflection of force-displacement curve of the viscous damper; the test results verifies the correctness of  the above conclusions.
