EN 61373 Random Vibration Test for Automotive Subsystems
The EU standard EN 61373, titled "Electromagnetic compatibility (EMC) of apparatus and instruments - Particular requirements for the protection of railway signals and interlocking equipment against interference from radio-frequency electromagnetic fields", specifies conditions under which railway signal and interlocking equipment must operate correctly. However, its relevance extends beyond just rail systems to include automotive subsystems due to their similar electronic complexities and potential to face harsh environmental conditions.
Random vibration testing is a critical procedure in the development process of automotive electronics, ensuring that components are robust enough to withstand vibrations encountered during vehicle operation. This test evaluates how well the electronic modules perform under random mechanical stress caused by road surfaces or other dynamic environments. The purpose behind this standard is to safeguard against failures that could lead to safety issues in vehicles.
The EN 61373 vibration test aims at replicating real-world conditions where vehicles traverse various terrains and experience different levels of shock and vibration. By simulating these scenarios, engineers can identify weaknesses within the design early on before mass production begins. This approach helps reduce costs associated with recalls or post-sale repairs while enhancing overall product reliability.
In practice, this involves placing a sample component onto a shaker table that generates controlled random vibrations over specified frequency ranges and amplitudes. The duration of each cycle varies according to the test conditions outlined in EN 61373. During the test, engineers monitor various parameters such as temperature changes within the enclosure housing the electronic circuitry and observe any signs of malfunctioning.
It is important to note that while EN 61373 focuses primarily on electromagnetic compatibility (EMC) aspects related to interference from radio frequencies, it indirectly addresses mechanical shock resistance through its vibration testing provisions. Therefore, when specifying this standard for use in automotive subsystems like onboard diagnostic systems or infotainment units, manufacturers ensure compliance not just with EMC requirements but also the durability needed against physical shocks encountered during driving.
Random vibration tests according to EN 61373 play a crucial role in safeguarding the integrity of critical electronic components used in modern automobiles. By adhering strictly to this standard during development stages, companies can enhance their products' quality and safety standards significantly.
