【摘要】 以声学理论和典型消声器结构为基础,结合振动噪声测试结果分析,设计一种新型消声窗结构,既要满足小尺寸消声窗降噪要求,又要保证变压器正常工作时的通风散热。基于SYSNOISE软件对消声窗消声量进行仿真,并为其工程化提供新思路。更多还原

【Abstract】 Based on the acoustic theory and the type structure of the muffler,combining with the interpretation result of the vibration and noise test,to design a new narrow-band noise which can meet the minisize demands as well as airiness and heat elimination.After that emulate to the sound deadening capacity of the acoustic enclosure with the software SYSNOISE,and provide a new method for engineering in the end.更多还原
