description The invention provides a test method for identifying the rotation fault of a compressor casing of a diesel engine matching turbocharger. The test method comprises the following steps: judging the reference state of a verification platform by means of overall vibration evaluation of a diesel engine, and rectifying a test bench which does not meet the requirements; designing test points by using thephysical characteristics of a test instrument and the rotation couple characteristics of a turbocharger volute; performing vibration data acquisition and typical characteristic post-processing on therotation fault of the compressor casing of the turbocharger; designing a suppression scheme for suppressing the rotation of the compressor casing of the turbocharger, analyzing a suppression way anda hypothesis implementation scheme, and determining a dredging and guiding mode of abnormal local stress; and pre-assessing the effect of hypothesis implementation scheme for suppressing the rotationof the compressor casing of
