Response Simulation of Non-Obstructive Particle Damping Structure Based on Extremal Properties of Endochronic Theory

非阻塞性颗粒阻尼(non-obstructive particle damping)是在传统颗粒阻尼和冲击阻尼技术基础上发展起来适用于恶劣环境、具有良好减振效果的一种复合阻尼新技术。通过利用极值特性的内时理论简化方法对NOPD结构响应进行了分析,并在此基础上进行了仿真计算和实验验证。结果表明,将内时理论简化方法应用于NOPD结构响应计算是可行的,为NOPD技术的工程应用提供了一种有效的分析方法。

Non-Obstructive Particle Damping (NOPD) is a new composite damping technology which is based on traditional particle damping and impact damping technique. NOPD technology is applicable to awful circumstance and has good effect on vibration absorption. In the paper the response of NOPD structure is analyzed by endochronic theory which is simplified by extremal properties. Computer simulation and experiment are done on the basis of it. Results show it feasible to calculate the response of NOPD structure by simplified endochronic theory, which afford an effective analysis method for engineering application of NOPD technique.
