以6PK型汽车多楔带为研究对象,首先,分析了多楔带传动噪声产生机理,基于振动特性分析与声学边界元分析相结合的方法,建立两轮多楔带传动噪声仿真预测模型,得到多楔带传动系统的噪声分布云图和幅频特性曲线。然后,基于声阵列测量原理搭建了多楔带传动噪声源识别装置,并进行转速对多楔带传动噪声影响规律的试验研究,得到不同转速下多楔带传动噪声的频域曲线和噪声分布云图。最后,通过仿真结果与试验结果的对比得知,在非共振区,噪声幅值随转速的增加而增大;在共振区,噪声幅值会发生明显增大,且高阶共振时的共振噪声幅值更大。试验结果比仿真分析结果高约4%。验证了理论分析和仿真方法的正确性,为汽车多楔带传动噪声预测提供了依据。
Taking 6PK type V-ribbed belt as the research object. Firstly, the mechanism of V-ribbed belt drive noise is analyzed, based on the method of combination of vibration characteristic analysis and acoustic boundary element analysis, the simulation and prediction model of two pulleys V-ribbed belt drive noise is established. The noise distribution nephogram and amplitude-frequency characteristic curve of V-ribbed belt drive system are obtained. Then, based on the principle of sound array technology, a noise source identification device for V-ribbed belt drive is set up, and the experimentally study of influence of rotating speed on V-ribbed belt drive noise is carried out. The frequency domain curve and noise distribution nephogram of V-ribbed belt drive noise at different rotating speeds are obtained. Finally, the comparison between simulation results and experimental results shows that in the non-resonance zone, the noise amplitude increases with the increase of rotating speed. In the resonance zone, the amplitude of the noise will increase sharply, and the amplitude of the higher order resonance is larger. The experimental results are about 4% higher than that of simulation analysis. The correctness of theoretical analysis and simulation method is verified, which provides a basis for the prediction of noise of automobile V-ribbed belt drive.
