Abstract
The invention discloses a kind of method for detecting vibration of headlight for vehicles, comprise the following steps：（1）Headlight for vehicles is arranged on simulated automotive and is powered and lights headlight for vehicles, simulated automotive bottom is fixed on a vibration table；（2）The vibration frequency and acceleration magnitude of shake table are adjusted, shake table drives simulated automotive vibration；（3）Switch headlight for vehicles once at regular intervals, and adjust the vibration frequency and acceleration magnitude of shake table；（4）Photosensitive detector is set in front of headlight for vehicles, records the headlight for vehicles brightness that a photosensitive detector detects at regular intervals；Vibration detection effect of the present invention is good, efficiency high, improves automobile lamp ability affected by vibration, ensure quality when automobile lamp dispatches from the factory and it is follow-up will not occur when using coming unglued because of vibration, cracking phenomena.
Description
Technical field
The present invention relates to a kind of detection method, more particularly to a kind of method for detecting vibration of headlight for vehicles, belong to Automobile
Lamp manufacturing technology field.
Background technology
Automobile lamp, it is in the case of night or low visibility, is provided to driver, passenger and traffic administration personnel
Illumination, to other vehicles and pedestrian play a part of prompt and alert, at present automobile lamp during the manufacturing not
Carry out vibration-testing, and automobile lamp is in actual use, due to being influenceed by running car road conditions, and enging cabin shakes
Dynamic, the influence of the vibration of each side to automobile lamp is also larger, and over time, automobile lamp is opened due to vibration
Glue, the phenomenon of cracking are more and more, ultimately result in automobile lamp damage, therefore, automobile lamp is during the manufacturing, to it
It is extremely important to carry out vibration-testing.
The content of the invention
To solve the deficiencies in the prior art, the present invention provides a kind of method for detecting vibration of headlight for vehicles, vibration detection effect
Fruit is good, efficiency high, improves automobile lamp ability affected by vibration, ensures quality when automobile lamp dispatches from the factory and follow-up use
Coming unglued occurs because of vibration in Shi Buhui, cracking phenomena.
The technical solution adopted in the present invention is：
A kind of method for detecting vibration of headlight for vehicles, comprises the following steps：
（1）Headlight for vehicles is arranged on simulated automotive and is powered and lights headlight for vehicles, simulated automotive bottom is fixed on shake table
On；
（2）The vibration frequency and acceleration magnitude of shake table are adjusted, shake table drives simulated automotive vibration；
（3）Switch headlight for vehicles once at regular intervals, and adjust the vibration frequency and acceleration magnitude of shake table；
（4）Photosensitive detector is set in front of headlight for vehicles, a photosensitive detector is recorded at regular intervals and detects
Headlight for vehicles brightness.
Further, the vibration frequency adjustment section of described shake table is 15-20Hz, and the adjustment section of acceleration magnitude is 1-
4G。
Further, step（3）Described in the headlight for vehicles of switch at regular intervals be once every 10 minutes switch vapour
Car headlight is once.
Further, step（4）Described in record the automobile that detects of a photosensitive detector at regular intervals big
Lamp brightness is the headlight for vehicles brightness detected every photosensitive detector of 5 minutes records.
Further, the duration of whole vibration detection process is 1 hour.
The beneficial effects of the present invention are：Vibration detection effect is good, efficiency high, improves automobile lamp energy affected by vibration
Power, ensure quality when automobile lamp dispatches from the factory and it is follow-up will not occur when using coming unglued because of vibration, cracking phenomena.
Embodiment：
Specific introduction is done to the present invention with reference to embodiment.
The present embodiment is a kind of method for detecting vibration of headlight for vehicles, is comprised the following steps：
（1）Headlight for vehicles is arranged on simulated automotive and is powered and lights headlight for vehicles, simulated automotive bottom is fixed on shake table
On；
（2）The vibration frequency and acceleration magnitude of shake table are adjusted, shake table drives simulated automotive vibration；
（3）Switch headlight for vehicles once at regular intervals, and adjust the vibration frequency and acceleration magnitude of shake table；
（4）Photosensitive detector is set in front of headlight for vehicles, a photosensitive detector is recorded at regular intervals and detects
Headlight for vehicles brightness.
In the present embodiment, the vibration frequency adjustment section of shake table is 15-20Hz, and the adjustment section of acceleration magnitude is 1-
4G。
The present embodiment step（3）In be every 10 minutes switch headlight for vehicles once.
The present embodiment step（4）In be every the headlight for vehicles brightness that detects of photosensitive detector of record in 5 minutes.
The duration of the whole vibration detection process of the present embodiment is 1 hour.
The inventive method vibration detection effect is good, efficiency high, improves automobile lamp ability affected by vibration, ensures automobile
Quality when car light dispatches from the factory and it is follow-up will not occur when using coming unglued because of vibration, cracking phenomena.
Described above is only the preferred embodiment of patent of the present invention, it is noted that for the common skill of the art
For art personnel, on the premise of patent principle of the present invention is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection domain of patent of the present invention.
