中文摘要: |
设计基于多媒体的轮胎花纹噪声智能测量分析仪,应用TNS/ODS分析优化软件,可测量轮胎花纹噪声的声压级。将噪声形成wav音频文件,通过二级定标引入A,B,C三档模糊(Fuzzy)计权网络,生成3档声压级,可执行时域、频域分析以及轮胎噪声性能评判。 |
英文摘要: |
A portable smart analyzer of tire tread noise has been developed on the basis of mutimedia.It can be used to measure the sound pressure level of tire tread noise with TNS/ODS analyzing and optimizing software.Three sound pressure levels are formed by introducing the wav sound file from the noise into A,B,C three-grade fuzzy weight network through two-level marking to carry out the analyses of time domain and frequency domain,and the evaluation of tire noise characteristics. |
