Abstract
The invention provides an automobile door noise testing system, for solving the problem of lack of an automobile door noise testing apparatus for the automobile industry in the prior art. The technical main points of the system are as follows: a vertical microphone support is arranged at a position which is 1 m away from the edge of one side of a test desk, a microphone is fixed at the top end of the microphone support, a data acquisition device is connected with the microphone and a digital tensiometer, the microphone is 20-185 cm away from the desk surface of the test desk, the digital tensiometer is arranged between the edge of the test desk and the microphone, and the two ends of the digital tensiometer are provided with rubber ropes. The advantages are as follows: objective data about automobile door-closing sound quality can be obtained, and the test method is direct, fast and effective. The application condition of the method is simple, the operation is easy, the versatility is quite high, the structure is simple, the operation is convenient, the cost is low, the practicality is high, and the like.
Description
Technical field
The invention belongs to vehicle performance technical field of measurement and test, particularly the close the door psychoacoustic parameter such as loudness, sharpness of sound of automobile is made the car door noise measuring system of test to sample sound.
Background technology
Automobile sound quality is under the requirement that meets human and environment, seek to meet the product sound of automobile characteristic, be the pith of auto NVH research, the quality of the height of automobile noise level and sound quality, directly affects people to the impression of car mass and purchases the selection tendency of car.Therefore, the design of automobile sound quality has caused the attention of acoustic engineers, becomes the important content of domestic and international well-known automobile in the time of design.System and the parts of on automobile, sounding are a lot, as the sound of the sound of the sound of motor car engine, closing of the door, Wiper blade and glass friction, the sound that hood is closed, sound and the sound of indicator etc. of wind excitation, these parts have the topic of sound quality, also affect the evaluation of client to automobile.Closing of the door sound can transmit to client the information of series of complex, as safety, comfortable, luxurious, reliable and confidence etc., is therefore highly significant to the sound quality research of car door.
But at present not about the car door noise-measuring system for automobile industry.
Summary of the invention
The object of this invention is to provide the close the door psychoacoustic parameter such as loudness, sharpness of sound of automobile and sample sound is made to the car door noise measuring system of test.
Specific embodiment of the invention scheme is: it is made up of test board, microphone arm, microphone, data collector, digital tautness meter, elastic string, be provided with vertical microphone arm at the 1m place, edge apart from test board one side, microphone arm top is fixed with microphone, data collector is connected with microphone and digital tautness meter, and microphone is apart from test board table top 20 ~ 185cm; Numeral tautness meter is arranged between test board edge and microphone, and the two ends of digital tautness meter are provided with elastic string.
Feature of the present invention is mainly to obtain the close the door objective data of sound quality of automobile, directly, efficiently, effective method of testing.The condition of the method application is simple, and easy operating, has very strong versatility, and experimentation cost is cheap.
