The invention discloses a method for testing the vibration transmission sensitivity of a part, and the method comprises the steps: processing a to-be-tested part to be in a free state, and determiningan excitation point and a response point on the to-be-tested part, loading corresponding preset excitation loads to all the excitation points on the to-be-tested part in sequence, obtaining actual amplitude values of all response points on the to-be-tested part correspondingly, comparing the actual amplitude values with a standard amplitude value, selecting and optimizing the structure of the to-be-tested part, and obtaining the vibration transmission performance of a single part, thereby improving the vibration transmission performance of the to-be-tested part, and achieving the valuation ofthe vibration transmission performance of a single part, so the structure of the single part is optimized accordingly, and therefore vibration and noise of the whole automobile body are accurately reduced, and the automobile
