Environmental test method for civil light and small UAV system Part 5.Impact test

1 Scope

This part of GB/T 38924 specifies the civil light and small unmanned aerial vehicle (take-off weight 0.25kg~150kg) system (including aircraft and Ground station) impact test requirements and methods, including test conditions, test equipment and instruments, test process, test interruption and recovery, test result evaluation And test report. This section applies to civil light and small drones that may experience impact environments during transportation, loading and unloading, and use (take-off weight is 0.25kg~150kg) system (including aircraft and ground station) to determine whether civilian light and small UAVs can withstand the impact of the impact environment.

3 Test conditions

3.1 Flight impact test conditions Test conditions are preferred to use actual measured values. If there is no actual measurement, the flight impact test value can refer to Table 1.The waveform adopts post-peak sawtooth wave, post-peak The shape of the sawtooth shock pulse and its tolerance limit are shown in Figure 1. Description. D --- Nominal pulse duration, in milliseconds (ms); A --- Nominal pulse peak acceleration, in meters per square second (m/s2); T1---The minimum pulse monitoring time when using a conventional impact testing machine, in milliseconds (ms); T2---The minimum pulse monitoring time when using the vibration generator, in milliseconds (ms). Figure 1 The shape of the sawtooth shock pulse of the back peak and its tolerance limit ......
