【摘要】：结合某型粘滞阻尼器,通过流体动力学分析软件Fluent对粘滞阻尼器模型进行了仿真分析。考虑使用中阻尼器硅油黏度随温度变化及活塞自重引起的应力变形等实际情况,对模型和仿真进行了调整和修正,最终达到了仿真和试验结果误差在5%以内的较高精度要求。研究了活塞长度和间隙等关键参数对间隙式粘滞阻尼器性能的影响,尤其是对速度指数和阻尼系数的影响规律。
[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.
