悬吊质量摆减振控制体系原理简单、安装方便、减振效果好，许多学者对其进行了研究，并将之应用于工程实践。然而，目前关于悬吊质量摆减振控制体系的研究，仍存在着如下严重不足：被动式悬吊质量摆忽略了摆的大振幅非线性和空间振动特性对减振性能的影响；自适应悬吊质量摆尽管能够提高减振性能，但是传感器和作动器又会带来系统的可靠性和稳定性问题。本项目针对悬吊质量摆减振控制体系研究中存在的不足，开展深入细致的研究，首先从理论上解决悬吊质量摆大振幅几何非线性及空间振动中的关键力学问题，包括体系阻尼矩阵的确定方法和非线性振动方程的求解；考虑到摆的大振幅非线性和空间振动特性，通过设计流线型支座来消除摆的大振幅非线性和空间振动对减振性能的影响，达到被动式自适应减振的目的；考虑悬吊质量摆的大振幅几何非线性、空间振动特性以及结构参数的不确定性，研究悬吊质量摆体系的参数优化设计方法。最后通过振动台实验验证理论分析的正确性。

The Suspended Mass Pendulum Damper (SMPD) has the advantages of simple theory, easy installation and great control performance. A lot of scholars have conducted the research about SMPD and applied it in engineering practice. However, there are still following serious limitations on the current research about SMPD. The nonlinearity under large amplitude and spatial vibration of pendulum are neglected for passive SMPD. Although adaptive SMPD can improve the control performance, the sensors and actuators will bring the problems of stability and reliability. This proposal will conduct the thorough research focused on the shortcomings of current research on SMPD. Some key mechanical problems of geometric non-linear and spatial vibration for SMPD will be solved, including the determination of the damping matrix of the system and the solution of nonlinear vibration equation. The streamline support will be designed to compensate the influences of large amplitude nonlinearities and spatial vibration of SMPD, which will achieve the objective of passive adaptive control. Considering the large amplitude nonlinearities, spatial vibration and parametric uncertainties, the method of optimal design for SMPD will be developed. Finally, the shaking table test will be performed to verify the correctness of proposed theory.
