Embodiment 1
[0094] The present embodiment one discloses a kind of test system used for air suspension airbag durability test, such as figure 1 As shown, the test system includes: an air compressor 2, an electromagnetic master valve 3, an air bag 5, an air storage tank 6, an actuator 7 and a test controller 10; wherein:
[0095] The air compressor 2 is electrically connected with the DC power supply 1 to form a power supply circuit, and a relay 4 is installed on the power supply circuit, and the power supply or disconnection of the DC power supply 1 to the air compressor 2 is realized by controlling the relay 4 to be closed or disconnected. Electricity;
[0096] A pressure relief valve 11 is integrally installed in the air compressor 2, and the air in the air compressor 2 is discharged by opening the pressure relief valve 11, so that the air pressure in the air compressor 2 is unloaded;
[0097] A temperature sensor 12 is also integrated in the air compressor 2, and the temperature sensor...
Embodiment 2
[0115] This embodiment 2 discloses a test method for air suspension airbag durability test, the test method described in this embodiment 2 is based on the test system for air suspension airbag durability test described in the foregoing embodiment 1, The test method includes: firstly carry out a round of failure test on the accompanying sample, after confirming that the accompanying sample is working normally, then carry out the endurance test on the air suspension airbag, and carry out the endurance test on the air suspension airbag During the test, control methods for emergencies were also set up.
