该文针对平面对称结构和不对称结构,比较TLCD-结构体系和TMD-结构体系的耦联微分方程,得到TLCD-主结构与TMD-主结构质量比、频率比、主结构自振频率和主结构阻尼等,由此可将TLCD-结构体系转化为TMD-结构体系,利用Den Hartog公式对TLCD阻尼比和频率比参数优化,并用有限元软件来对复杂结构减振控制进行数值计算。通过单层平面不对称结构和20层Bechmark模型放置单个或多个TLCD,用Den Hartog公式求得TLCD参数,并用SAP2000进行结构分析,与MATLAB结果进行比较来验证该方法的合理性和可行性。
In this paper, the coupling differential equations of TLCD-TMD and TMD-TM are compared for planar symmetry and asymmetric structures. The mass ratio of TLCD-TMD to TMD, frequency ratio, Structure damping and so on, thus the TLCD-structure system can be transformed into TMD-structure system. The damping coefficient and frequency ratio parameters of TLCD are optimized by Den Hartog formula. The finite element software is used to calculate the damping control of complex structure. Single or multiple TLCDs were placed by single-layer planar asymmetric structure and 20-layer Bechmark model. The TLCD parameters were obtained by Den Hartog formula, and the structural analysis was carried out by using SAP2000. Compared with MATLAB results, the method was verified to be reasonable and feasible.
