摘　　要：以义马某气化炉厂房为研究对象,通过有限元软件ANSYS构建厂房模型,分析了在矩形脉冲周期激励下结构的响应。把厂房中的主要设备(气化炉)作为TMD控制系统的惯性质量,设计了TMD控制系统。对安装TMD控制系统的框架结构的动力性能进行了分析,计算结果显示:TMD装置对矩形脉冲周期激励下的反应控制良好,减振效果在60%以上。Taking a gasification furnace workshop in Yima as investigated object,using the finite-element program ANSYS,the response of the structure under rectangular cyclic impulse excitation is researched.The TMD control system is designed,and the gasification furnace is considered as inertial mass of the system.The dynamic performance of the frame structure with the TMD control system was analyzed.The results show that the structural responses under the excitation are effectively reduced by 60% at least by the TMD system.
