某型艇舱室次声场环境模拟装置的研究

目的 建立某型艇舱室次声场环境模拟装置。方法 通过对甲板及各舱室的次声声压级、频谱进行测量及对次声场辐射状况进行分析,得出该型艇二次次声产生的原理。结果 研制了符合实艇次声环境的模拟装置。结论 该模拟装置产生的次声场与实艇环境工况相吻合,可为治理措施的制订和治理效果的评估提供基础性支撑。

A simulation device of infrasound field in the cabin of a certain naval boat

Objective To develop a simulation device of infrasound field in the cabin of a certain naval boat. Methods Through detection of the infrasound pressure levels and noise spectrum on the deck and in the cabins and analysis of the infrasound field radiation, the principle of secondary infrasound induction was thus obtained. Results The simulation device that complied with real boat infrasound environment was developed successfully. Conclusion The infrasound field generated by the simulation device coincided with the real boat infrasound environment, which could provide basic support for the development of control measures and assessment of control effects.
