Abstract

ABSTRACT The inertial amplifier viscoelastic base isolators (IAVBI) are introduced in this paper. The viscoelastic materials are implanted inside the core material of the inertial amplifier base isolators. The standard linear solid (SLS) models are applied to formulate the viscoelastic material mathematically. The viscoelastic materials are also implanted inside the traditional base isolators to enhance their dynamic response reduction capacity. The optimal dynamic responses of structures controlled by novel viscoelastic base isolators are derived analytically. The exact closed-form expressions for optimal design parameters of novel viscoelastic base isolators for structures are derived using and optimization methods. The feasibility of these optimal design parameters has been tested by frequency domain analysis. The optimal dynamic response reduction capacity of inertial amplifier viscoelastic base isolators has been determined to investigate the robustness of the and optimized design parameters. The closed-form expressions for optimal design parameters of novel base isolators are mathematically correct and effective for design purposes.
用于减缓结构动力响应的最佳惯性放大器粘弹性基隔振器的分析研究
本文介绍了惯性放大器粘弹性基底隔离器(IAVBI)。粘弹性材料被植入惯性放大器基座隔离器的核心材料内部。应用标准线性固体(SLS)模型对粘弹性材料进行数学公式化。粘弹性材料也被植入传统的基础隔震器中,以提高其动态响应降低能力。分析推导了新型粘弹性基础隔震器控制下结构的最优动力响应。利用和优化方法,导出了结构用新型粘弹性基础隔震器优化设计参数的精确闭合表达式。通过频域分析验证了这些优化设计参数的可行性。确定了惯性放大器粘弹性基础隔震器的最佳动态响应衰减能力,以研究其鲁棒性和优化设计参数。新型基础隔震器优化设计参数的闭合表达式在数学上是正确的,对设计目的是有效的。
