[Abstract]:The model of viscous damper is simulated by the fluid dynamics analysis software Fluent. Considering the fact that the viscosity of silicone oil in medium dampers varies with temperature and the stress and deformation caused by piston weight, the model and simulation are adjusted and corrected, and the accuracy of simulation and test results is higher than 5%. The influence of the key parameters such as piston length and clearance on the performance of the clearance viscous damper, especially on the velocity exponent and damping coefficient, is studied.
