摘　　要：一种能控制盖板下落速度的旋转阻尼器的性能取决于其内部圆柱凸轮机构、弹簧与黏滞阻尼器。为计算旋转阻尼器系统的性能,对凸轮机构的传动作用与弹簧和黏滞阻尼器的输出特性进行分析;建立旋转阻尼器系统盖板下落过程的动力学理论计算模型,采用龙格-库塔法对该模型进行计算;应用该模型对旋转阻尼器各部件参数的匹配进行分析;通过实验验证该计算模型的准确性。结果表明:该计算模型可用于旋转阻尼器的参数匹配设计。The performance of a rotary damper which can control the falling speed of the cover plate depends on its internal cylin⁃drical cam mechanism,spring and viscous damper.In order to calculate the performance of the rotary damper system,the transmis⁃sion action of the cam structure and the output characteristics of spring and viscous damper were analyzed;a theoretical calculation dy⁃namic model of the falling condition of rotary damper system was created and calculated by using Runge-Kutta method;the model was used to analyze the parameter matching of the viscous damper;the accuracy of the calculation model was verified through experiment.The results show that the model can be used for parameter matching design of the rotary damper.
