摘要: 基于有限元法对管道系统在泵激励下的振动特性进行分析,以管系传至基础的振动功率流最小为目标,采用基于Matlab开发的优化分析(遗传算法)平台对管道系统支吊架的位置以及刚度进行优化设计,在保证系统抗冲击能力的前提下,达到降低管系振动的目的。通过分析得知,在管道系统的振动控制中,支吊架位置参数的调整及刚度特性的变化是降低管道振动的有效方法。Abstract: Based on an engineering project, finite element analysis on vibration characteristics of piping system under the excitation of the pump is carried out. Then, by using the genetic algorithm, vibration attenuation is achieved by optimizing the positions of the supports of the piping system with the goal of minimizing the vibration power flow. And antishock performance of piping system must be ensured. The results show that at the aspect of vibration control of piping system, the adjustment of the position of the supports is another effective method for reducing the piping vibration.
