基于调频型颗粒阻尼器(Tuned Particle Damper,TPD)的简化线性分析模型-双调谐质量阻尼器(Doubly Tuned Mass Damper,DTMD)模型建立了TPD的数值优化方法,对TPD的参数进行了分析和优化,建立了TPD的简化非线性分析模型及其参数计算法,并利用该简化非线性分析模型对上述TPD数值优化法进行评价。理论和数值研究结果表明:与单TMD相比,TPD简化线性分析模型-DTMD的减震频带更宽,控制效果的鲁棒性更好。依据数值优化方法得到的TPD具有良好的减震控制效果;TPD简化非线性分析模型及其参数计算方法,可为颗粒阻尼器的应用提供理论和数值分析指导。
Based on the simplified linear analysis model of Tuned Particle Damper (TPD) - Doubly Tuned Mass Damper (DTMD) model, a numerical optimization method of TPD was established and the parameters of TPD were analyzed and optimized , A simplified nonlinear analysis model of TPD and its parameter calculation method are established, and the simplified TPD numerical optimization method is evaluated by using the simplified nonlinear analysis model. Theoretical and numerical results show that, compared with single TMD, TPD simplified linear analysis model-DTMD has a wider damping band and better control effect. The TPD obtained by the numerical optimization method has a good damping control effect. The TPD simplified nonlinear analysis model and its parameter calculation method can provide theoretical and numerical guidance for the application of the particle damper.
