The present invention discloses a noise detection method of an oil tank. The method comprises the steps of (1) fixing the oil tank to a rocking bench, and carrying out the shaking of multiple angles of a simulation road condition on the oil tank, (2) sensing the sound decibel in the oil tank and judging the decibel of sound, (and 3) reducing the shaking angle of the oil tank until the sound decibel of the oil tank is equal to a preset decibel in the condition that the sound decibel exceeds a preset decibel, and storing the shaking angle value of the oil tank, or increasing the shaking angle of the oil tank until the sound decibel of the oil tank is equal to the preset decibel in the condition that the sound decibel is lower than the preset decibel, and storing the shaking angle value of the oil tank. According to the noise detection method, the problem that the oil tank decibel value in the use process of the oil tank can not be detected in the prior art is overcome, and the noise detection of the oil tank is achieved.
Description
technical field [0001] The invention relates to the field of noise detection of fuel tanks, in particular to a noise detection method of fuel tanks. Background technique [0002] Automobile fuel tank is the full name of automobile fuel tank. At present, with the development of the automobile industry and the revitalization of the domestic automobile industry, the demand for automobile fuel tanks by major automobile manufacturers is showing an obvious growth trend. [0003] During the use of the fuel tank, the noise of the fuel tank may be too large due to the unstable road conditions. The fuel tank should have a certain sound insulation effect, but whether the sound insulation effect of the fuel tank meets the requirements and how to detect it is an urgent problem in this field. . Contents of the invention [0004] The object of the present invention is to provide a noise detection method of a fuel tank, which overcomes the problem in the prior art that the decibel value...
