非阻塞性微颗粒阻尼（ＮＯＰＤ）是在传统颗粒阻尼和冲击阻尼技术基础上发展起来的一种复合阻尼新技术，具有良好的阻尼特性，因而表现出极佳的减振效果．文中建立了用于非阻塞性微颗粒阻尼分析的散体单元法模型（球体元模型），利用接触力学理论合理地确定了各接触参数，对非阻塞性微颗粒阻尼中的冲击能耗和摩擦能耗进行了计算机仿真研究．计算机仿真结果与实验结果有很好的一致性，为ＮＯＰＤ理论分析提供了一种新方法
Non-obstructive micro-particle damping (NOPD) is a composite damping technology developed on the basis of traditional particle damping and impact damping technology. It has good damping characteristics and thus shows excellent damping effect. In this paper, the discrete element method (spherical element model) for the non-obstructive micro-particle damping analysis is established. The contact parameters are reasonably determined by the contact mechanics theory. The impact energy and friction Energy consumption was studied by computer simulation. Computer simulation results are in good agreement with experimental results, providing a new method for NOPD theoretical analysis
