Abstract

A noise investigated in this study is the pulsation noise generated from compressor wheels, whose frequency is the same as the whine noise. Although they have the same frequency, their noise sources are absolutely different. The whine noise is induced from the unbalance of rotating modules, on the other hand, the pulsation noise is found to be generated by breaking the wheel’s dimensional symmetry by tests. This asymmetry considered in this study is done by cutting partly compressor wheels’ edge in order to remove its unbalance in a semicircular shape. It was realized by tests that the number is directly related to the level of the pulsation noise, and a specific number exists to cause the noise problem. Additional tests have been done to investigate the characteristics of the noise by changing the numbers, the size, and the arrangements of the cuttings. Finally, this study concludes that the pulsation noise is related to the three factors of cuttings.
