惯性平台新型金属橡胶减振器理论与实验研究

金属橡胶减振器（以下简称MRD）是为克服目前惯性平台常用橡胶减振器随时间老化这一致命弱点而开发研制的一种新型减振器，其在航空航天等军事领域具有广阔的应用前景，但目前主要依靠经验和试凑进行设计和加工，缺乏系统的理论基础。对其动态特性参数与工艺安装参数之间关系的研究在国内一直是个空白，对于这一动力学前沿课题的研究，具有重要的理论与工程应用价值。本文建立了MRD的力学模型，通过对其力学模型的分析与研究，给出了MRD系统非线性特征参数的参数识别方法；通过实验验证了其力学模型和参数识别方法的合理性。提出了MRD的特性参数与工艺安装参数关系的研究策略及其优化设计技术研究的主要内容。

Theory and experiment research on a new type of metal rubber damper for inertial platform

Metal rubber damper (MRD) is a new kind of damper for inertial platform,which is devoted to overcoming fatal weakness-aging with time.Although MRD has a wide application prospect in the military field of aerospace etc,lacking of systematic theoretical basis,designing and machining MRD is mainly dependent on experience and test.Research on the dynamics is of great value in theory and engineer applications,but there are always gaps in research on the relationship between MRD dynamic property parameters and technological assembly parameters in China.In this paper,a MRD dynamic model is set up,and by analyzing and research on it a parameter identification method of MRD system's nonlinear characteristic parameter is obtained.Then,rationality of the dynamic model and parameter identification method is verified by experiment.Finally,the relationship between MRD characteristic parameter and technological assembly parameter and MRD optimal design technique is given.
