Based on the theory of dynamic vibration absorber, a class of structure resonators equipped with additional vibrators is put forward to suppress fluid pulsation which causes system unstable or reduces work performance. Working principle of resonators is explained from mechanics and three kinds of elements are used to work as additional vibrators, namely round metal sheet, rectangular metal sheet, round rubber membrane. Multiple vibrators are designed into one resonator to damp the pressure pulsation in system over a wide range of frequency. Mat...
