vehicle electronic equipment testing

vehicle electronic equipment is applied to road vehicles or railway vehicles of electronic appliances, electronic devices or components. in the process of research and development and production, a lot of vehicle engineering technology and electronic engineering technology are integrated. it's a very technical electronic device. with the continuous development of science and technology, the structure of vehicle engineering has changed from monotonous mechanical products to electronic products. at the same time, with the application of wireless communication in vehicles, the increase of occupant comfort needs, and the conversion between mechanical and electronic systems, the application of electronic products and electronic devices in vehicles is increasing, and the proportion of electronic components is increasing. therefore, in order to ensure the safety of vehicles, in order to further improve the quality and reliability of vehicle electronic products, it is necessary to carry out targeted test and certification of related products.

q&a

what tests are required according to gb/t 25119-2010?

visual inspection；performance test; power supply test; cold start test; dry heat test; damp heat test cyclic; insulation resistance test; voltage withstand test; salt mist test; vibration and shock test.

what are the vehicle electronic products included?

power supply products, entertainment related audio and video products, occupant service equipment, environment regulation equipment, various lighting control systems related to safe exercise, monitoring related equipment and related navigation, radar, etc.

what are the requirements for shock and vibration in gb/t 21563-2018?

in the process of rolling stock moving up the track, due to the impact and vibration of the rail, it may cause looseness of fasteners, fracture of leads and mechanical damage of components. the standard adopts random vibration, which is closer to the actual situation of rail transit. in addition, the longitudinal impact acceleration is 5g, and the waveform generated by the impact should not only meet the requirements, but also have requirements for the bottom width of the pulse waveform, which truly reflects the impact of the hammer.

what tests are required according to gb/t 24338.4-2018?

conduction emission；radiated emission；rf common mode；fast transient；surges；rf electromagnetic field amplitude modulation；electrostatic discharge, etc.
