| Abstract: |
| This paper aims to improve the product quality of civil light and small unmanned aerial vehicle (UAV) enterprises, to improve the comprehensive test ability of relevant environmental test personnel, and to improve the technical level of industry tests. On the basis of GB/T 38924—2020 series standards, the environmental test methods of civil light and small unmanned aerial vehicles (UAV) were analyzed. In this paper, the influence factors of the environmental test of civil light and small unmanned aerial vehicle (UAV) systems are analyzed, mainly including the climatic and mechanical environmental factors. The climatic environmental test method and mechanical environmental test method were compared and analyzed. According to GB/T 38924—2020 series standards, the specific test parameters were analyzed. The temperature change rate of temperature test is not more than 3 ℃/min; the pressure change rate of low pressure and high-pressure test is not more than 4.8 kPa/min; the salt spray test is divided into continuous spray mode and intermission spray mode. The main parameters of the waterproofness test are raindrop diameter and spray water quantity. The main parameters of the sand and dust test are dust concentration and sand concentration. Dust-blowing velocity and sand-blowing velocity; the main parameters of the impact test are peak acceleration and pulse time. The main parameters of the vibration test are spectral density, amplitude, acceleration and sweep frequency rate, the test parameters of shock test and vibration test should be selected according to the type of unmanned aerial vehicle (UAV) and take-off weight. According to the relevant standards, a test parameter of shock test and vibration test were selected to carry out the test, and the test curves were obtained. The test results are reliable, and some suggestions for some environmental tests were put forward. |
