中文摘要:
      汽车车轮空气室声共振对车内噪声有重要贡献,谐振器作为有效的噪声控制措施,在研制过程中降噪效果评估常用轮胎振动测量和路试测量方法,该方法较为复杂繁琐。提出了一套声管测量方法,对其测量原理、测试平台设计和关键技术及测量评价方法进行描述。对某谐振器利用建成的测量平台与振动测量及路试比较表明,提出的声管测量方法用于车轮空气室谐振器降噪效果评估合理,且简单易行、准确可靠。
英文摘要:
      The acoustic resonance of wheel air chamber is an important contribution to the interior noise of car. The resonator is an effective control mean to the acoustic resonance. However, it is complicate and tedious to evaluate the noise reduction effect of resonator by wheel vibration measurement and vehicle road test in its development process. A set of acoustic pipe measurement method is proposed in this paper. Its measurement principle, test platform design, key techniques and measurement evaluation method are described. Compared with vibration measurement and road test, the results show that the acoustic pipe measurement method is reasonable, simple, accurate and reliable.
