Gasoline engine supercharger vibration test method

The invention discloses a gasoline engine supercharger vibration test method, and belongs to the technical field of supercharger test. The method comprises the following steps that S1, a vibration sensor is additionally arranged on the supercharger, and preparation work before a test is conducted; S2, test execution conditions are controlled; s3, performing a test; and S4, repeating the step S3 for at least two times. According to the method, the working state and reliability of the supercharger are judged by testing the vibration condition of each key part of the supercharger in the acceleration and deceleration processes of the engine, powerful data are provided for simulation design, manufacturing process, material selection and the like of the supercharger, the supercharger is prevented from being damaged due to excessive vibration, meanwhile, empirical data of vibration of the supercharger can be accumulated, and the reliability of the supercharger is improved. The device can rapidly measure the vibratio
