摘要:
为了减小热风炉阀在运行时噪音对周围居民的影响，运用有限元分析软件ANSYS对某热风炉阀结构及周围声场进行分析.在流体运动管道声场、小孔喷注消音等相关理论基础上，建立了结构、流体、声场有限元模型.通过建模、划分网格、加载、求解以及后处理等步骤，对该阀体及附近区域流体进行声振耦合计算分析.结果表明：带孔板结构在孔径为4 mm时，厚度为20 mm时，该阀体的结构形式的消音效果比到较理想，能为热风炉阀减噪设计提供一定的参考依据.
Abstract:
To reduce the influence of noise from the hot blast stove valve at run time on the surrounding residents, we used the finite element analysis software ANSYS to analyze the hot blast stove valve structure and the surrounding sound field .The finite element model of structure, fluid and sound field was established on the base of pipe sound field of fluid motion, noise reduction of small hole injection and other related theory. Acoustic vibration calculation of the valve structure and the nearby fluid was performed after steps of modeling, mesh, loading, solving and post\|processing, etc. The results show that the silencing effect of the body structure is better when the perforated plate structure is 4 mm in pore diameter and 20 mm in thickness, which provides certain reference for the design of hot blast stove valve noise reduction.
