Embodiment Construction

[0048] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the accompanying drawings only show some but not all of the parts related to the present invention.

[0049] like Figure 1 to Figure 4 As shown, this embodiment provides a vibration and noise testing system for performing vibration and noise testing on a test product. In this embodiment, the test products mainly refer to auto parts, such as front and rear seats, instrument panel, center console, body, front and rear doors, brake assembl...

Abstract

The invention relates to the technical field of vibration noise test, and discloses a vibration noise test system, the area of a first horizontal test board is smaller than that of a second horizontal test board, and the installation requirements of test products of different sizes can be met; the first vibration exciter and the second vibration exciter can be selectively connected with the first horizontal test board or the second horizontal test board, and the first vibration exciter can be used for driving the first horizontal test board or the second vibration exciter can be used for driving the second horizontal test board according to actual requirements. Or the first vibration exciter and the second vibration exciter are used for simultaneously driving the second horizontal test board and the like, so that the requirements of different test products on parameters such as vibration frequency, thrust and displacement are met, and the test flexibility is high; before a vibration noise test is carried out on a test product, the horizontal test bench and the vibration exciter which are not used are moved out of the test area through the inlet and outlet, the inlet and outlet are blocked by the blocking plate, and then the vibration noise test is carried out, so that noise reflection can be avoided.

Description

technical field [0001] The invention relates to the technical field of vibration and noise testing, in particular to a vibration and noise testing system. Background technique [0002] There is vibration during the driving process of the vehicle. The vibration of the vehicle will cause abnormal friction noise or impact noise between the auto parts. In order to improve the safety and comfort of the vehicle during driving Parts are tested for vibration and noise. [0003] The current vibration and noise test method is to place the component to be tested in a semi-anechoic chamber and fix it on the test platform, provide vibration for the test platform through a vibration source, and determine the noise level during the test process by collecting the sound in the semi-anechoic chamber. In order to realize the vibration and noise test of the parts to be tested. [0004] In order to improve the versatility of the vibration and noise test system and meet the vibration and noise ...
