| Abstract: | Taking the framework of a digitally controlled as an experimental object oil pump (so called )" framework body" for short) and adopting single site excitation and multiple-spot pick up of vibration, various analog outputs can be converted to logic one by using afrequency analyzer. The mode parameters of the framework body are obtained from the experimental data by using vibration mode theory and the law of mechanical impedance, providing the basis for finding the vibration origin as well as the damping method. |
