DN65通海阀声学特性分析

摘要

以典型DN65通海阀为对象，采用数值仿真的手段，对通海阀声学现状和结构特性进行分析研究。同时，利用LMS振动测试仪器对DN65通海阀的模态频率和模态阻尼进行了测试，对比分析仿真计算和试验测试的结果，证明了仿真计算的可信性和正确性。%Targeted at the typical DN65 sea valve, using numerical simulation method to study the acoustic status and structure characteris-tics of the sea valve. At the same time, using the LMS vibration testing instrument to test the modal frequency and modal damping of the DN65sea valve, contrasted the simulation results and the testing results, the credibility and correctness of simulation calculation’s results was been proved.
