考虑系统需求的通海阀箱结构声学优化

摘要

考虑管路系统功能需求，改变阀箱内部结构以及外形尺寸，建立7个方案的阀箱计算分析模型。通过利用数值计算方法，对阀箱出口处3个监测点的声压级进行计算。在此基础上，对各监测点计算结果进行对比分析，进而得到通海阀箱结构的声学最优模型。%By changing the internal structure and overall dimensions of the sea chest, seven sea chests calculation model were installed considering pipe system requirement. Using numerical calculation method, sound pressure level of three points of sea chests were calculated. On the basis of these, the calculation results of these points were compared and analyzed. In the end, the acoustic optimization model was got.
