化工装置结构-设备耦合体系协同减震优化控制策略
Optimized Control Strategy of Chemical Plant Structure-equipment Coupling System for Cooperative Damping
大型化工装置结构-设备耦合体系地震响应规律复杂,仅依靠提高化工装置结构本身抵抗地震能力的方法难以满足生产工艺需求。为了减小化工装置结构-设备耦合体系的地震响应,以地震时结构和设备的振动同时得到控制为优化目标,研究了化工装置结构-设备耦合体系阻尼装置多目标优化减震控制策略,对化工装置结构-设备耦合体系进行了地震响应控制分析。结果表明:以结构层间位移和设备加速度形成的优化性能指标及构建的目标函数,能够较好地解决阻尼器在装置结构中的优化布置问题。单目标优化时,工况一(设备为等效荷载)与工况二(设备为实体模型)层间位移的平均减震率分别为37.78%和32.83%,设备位移和加速度的最大减震率分别为18.73%和17.13%;多目标优化时,其层间位移的平均减震率为31.17%,设备位移和加速度的最大减震率分别为24.16%和25.07%。这些研究结果可为保障此类装置的安全可靠性提供技术支持。
The seismic response law of the structure-equipment coupling system of a large-scale chemical plant is complicated, and it is difficult to meet the demands of the production process only by improving the seismic resistance of the structure of the chemical plant itself. In order to reduce the seismic response of the chemical plant structure-equipment coupling system, the vibration of the structure and equipment during the earthquake was taken as the optimization goal, and the multi-objective optimization seismic damping control strategy of the chemical plant structure-equipment coupling system damping device was researched, and the seismic response control analysis of the chemical plant structure-equipment coupling system was carried out. The results show that the optimized performance index formed by the structural inter-story displacement and equipment acceleration and the constructed objective function can better solve the problem of optimized damper arrangement in the device structure. When single-objective optimization is performed, the average damping rates of inter-story displacement in Case 1 (the equipment is equivalent load) and Case 2 (the equipment is a solid model) are 37.78% and 32.83%, respectively, and the maximum damping rates of the equipment displacement and acceleration are 18.73% and 17.13%, respectively; When multi-objective optimization is performed, the average damping rate of the inter-story displacement is 31.17% and the maximum damping rates of the equipment displacement and acceleration are 24.16% and 25%, respectively. Were 24.16% and 25.07%, respectively. These results can provide technical support for ensuring the safety and reliability of such devices.
