Problems solved by technology

[0005] In addition, a key issue in the design of artificial simulation experiments is "how long to test in the laboratory, and its effect is equivalent to that of outdoor experiments for one year"
If the conversion is simply based on the amount of radiation and the influence of other environmental conditions is ignored, the result will have a large deviation

Embodiment 1

[0024] The test vehicle was placed in Qionghai, Hainan, my country, at the Humidity and Heat Natural Exposure Test Site to carry out the natural exposure test of the whole vehicle. Install solar radiation sensors, pasted temperature sensors, and suspended air temperature and humidity sensors on the surface of major interior components, and all instruments record data every 5 minutes. And use the solar spectrum sensor to test the solar spectrum distribution through the car glass to the surface of the interior parts to be inspected once every half month. Perform statistical processing on the data of the whole vehicle exposed to natural sunlight for one year, and obtain the solar spectrum distribution map through the window glass, the solar radiation intensity data through the car window glass when the sun is the strongest, and the surface temperature of the interior parts when there is sunlight The statistical average data of the statistical average data and the statistical aver...

Embodiment 2

[0028] The test vehicle was placed in the dry heat natural exposure test field in Turpan, Xinjiang, my country to carry out the natural exposure test of the whole vehicle, and the rest of the operation steps were the same as in Example 1. According to the test results, the main parameters of the xenon lamp test for the weather resistance quality control of the automobile dashboard are shown in Table 2.

Embodiment 3

[0032] The test vehicle was placed in Qionghai, Hainan, my country, to carry out the natural exposure test of the whole vehicle, and the solar radiation sensor, temperature sensor and air temperature and humidity sensor recorded data every 10 minutes, and the rest of the operation steps were the same as in Example 1. . According to the test results, the main parameters of the xenon lamp test for the weather resistance quality control of the automobile dashboard are shown in Table 3.

Abstract

The invention discloses a method for controlling the weather resistance of automobile interior parts by using a xenon lamp test, which comprises the following steps: (1) collecting the service environment data of automobile interior parts according to the natural exposure test of the whole vehicle; The quantitative model calculates the environmental stress value of the interior parts under the synergy of radiation and temperature received by the interior parts within one year of exposure; (3) uses the xenon lamp test to simulate the service environment conditions of the interior parts; (4) calculates according to the equivalent aging theory Xenon arc test time at the same environmental stress value. This method utilizes the xenon lamp acceleration test to simulate the influence of solar radiation, temperature and air temperature and humidity on the interior parts of the car during the natural exposure of the car, and evaluates the weather resistance quality of the interior parts according to the test results, so as to realize the evaluation of the interior parts of the car. The weather resistance quality control of decorative parts is fast, easy and easy to operate.

Description

technical field [0001] The invention relates to a method for controlling the weather resistance quality of automobile interior parts by using a xenon lamp test, belonging to the field of product quality detection and evaluation. Background technique [0002] During the service period of the car, it will face the test of various environments, especially the long-term effects of climatic factors such as light, cold and heat, wind and rain. If the quality of parts and materials is not properly selected, it will lead to premature failure and affect the appearance and performance of the car. Even safe. In order to control the weather resistance quality of automobiles, it is necessary to design appropriate environmental tests to test the weather resistance of automobiles. [0003] Cars are mainly in two states, dynamic and static, during their life cycle. Dynamic is the driving state of the car. Due to the relative flow with the air and the adjustment of the air-conditioning sys...
