The random vibration standard for automotive electronic components is established to ensure that automotive electronic components can work normally in vibration environments. This standard mainly involves the electrical performance, mechanical performance, and environmental adaptability of components during vibration, which helps to improve the stability and reliability of automotive electronic components.

Random vibration refers to the random external force acting on automotive electronic components during operation, which may cause mechanical displacement, stress, and fatigue issues of the components, thereby affecting their performance and reliability. In order to regulate the impact of random vibration on automotive electronic systems, the automotive industry has proposed a series of standards, including random vibration standards.

According to the standard requirements, the test of automotive electronic components in random vibration environment requires a series of tests such as frequency response analysis, phase analysis, power spectral density analysis, etc. Among them, frequency response analysis involves the response of components to external forces at different frequencies, including amplitude and phase; Phase analysis is the analysis of the phase differences in the vibration of components in response to external forces; Power spectral density analysis is to process the vibration signal and obtain the power spectral density of the vibration signal.

This standard is applicable to various automotive electronic components, covering various types such as sensors, controllers, drivers, communication devices, display devices, etc. In addition, the standard also specifies different vibration testing levels, namely A level, B level, C level, and D level, and the corresponding vibration intensity and testing requirements for different levels are also different.

In the process of formulating this standard, professional technicians conducted extensive testing and research on automotive electronic components in order to develop testing standards suitable for automotive vibration environments. Yes, the implementation of the standards will provide strong guarantees for improving the quality and reliability of automotive electronic components, and also inject new impetus into the development of the automotive industry.

The main purpose of formulating random vibration standards for automotive electronic components is to ensure the reliability and stability of automotive electronic systems. Specifically, random vibration standards can play the following roles:

Ensure the mechanical performance of automotive electronic components. Random vibration standards can evaluate the mechanical performance of automotive electronic components, including stress and fatigue performance, to ensure the stability and reliability of components during long-term operation.

Improve the anti-interference ability of automotive electronic systems. Random vibration standards can help automotive electronic systems better cope with external interference, thereby improving the system's anti-interference ability and ensuring its normal operation.

Reduce the failure rate of automotive electronic systems. By establishing random vibration standards, the operating environment of automotive electronic components can be standardized, the failure rate of components can be reduced, and thus the failure rate of automotive electronic systems can be reduced.

In summary, random vibration standards are an important means to ensure the reliability and stability of automotive electronic systems. By developing random vibration standards, the operating environment of automotive electronic components can be standardized, the mechanical performance of components can be evaluated, and the stability and reliability of automotive electronic systems can be ensured during long-term operation.
