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.

Abstract

The invention discloses a method for controlling the weather fastness quality of an automotive trim part by utilizing a xenon lamp test. The method comprises the following steps: (1) collecting service environment data of the automotive trim part according to a finished automobile natural exposure test; (2) calculating an environmental stress value under a synergistic effect of radiation and temperature on the trim part in exposure duration of one year by utilizing a dual-environment-factor stress quantitative model; (3) simulating service environment conditions of the trim part by utilizing the xenon lamp test; and (4) calculating the xenon lamp test time according to the equivalent aging theory when the same environment stress value is realized. The method is used for simulating the influence of solar irradiation, temperature and air humidity on the automotive trim part in the natural exposure process by utilizing the xenon lamp acceleration test, and the weather fastness quality of the trim part is evaluated according to a test result so that the weather fastness quality of the automotive trim part is controlled, and the method is rapid, simple, convenient 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...
