Bogie-Mounted Electronics and Brake Systems

Electronic systems located on train bogies or air supply compressors for braking systems situated under vehicles or inside are subjected to significant shock and vibration during operation.

These permanent vibratory phenomenon dynamic inputs are prone to cause wear out these equipments by fatigue, potentially leading to early mechanical wear failure.

SOCITEC offers a full range of wire rope isolators with an unlimited lifespan when properly sized and designed, designed capable of withstanding to withstand extreme temperatures and humidity levels.

Our shock and vibration solutions protect the onboard systems to preserve their functionality and durability.

Bogies sit at the point of maximum mechanical stress on a train: every irregularity in the track is transmitted directly into the equipment mounted on or under them. Moreover, compressors providing the air supply to braking systems generate vibration damageable to passenger comfort if not properly isolated, with no suspension stage in between for many onboard systems. Their elastic mounting also reduces stresses and increases lifetime.

Unlike a single shock event, this vibration is permanent across the entire operating life of the vehicle — often decades — so even a small unmitigated resonance builds up into significant fatigue damage over time.

Components also face wide temperature variations and humidity exposure underneath the vehicle, which is why isolation solutions in this zone need both vibration performance and long-term environmental durability.
