Switch rail locking mechanism: BYDRecent Research Landscape

Unintended switch movement during high-speed rail transit causes catastrophic derailment risks. These innovations engineer positive mechanical constraints to ensure structural integrity under heavy dynamic loads.

What technical problems is BYD addressing in Switch rail locking mechanism?

Insecure turnout switch positioning

(24)evidences

Mechanical misalignment or failure to lock during turnout transitions causes derailment risks. Ensuring precise positioning prevents catastrophic structural failure during high-speed transit.

Track beam surface slippage

(20)evidences

Ice accumulation and geometric irregularities compromise the safe interface between the vehicle and the rail beam. Addressing these ensures continuous operational reliability and prevents derailment risks.

Rail switch ice accumulation

(14)evidences

Frozen precipitation obstructs mechanical movement of rail switching components. Preventing mechanical blockage ensures operational safety and prevents transit delays.

Thermal expansion misalignment

(4)evidences

Inadequate electrical return paths in rail systems cause electrolytic corrosion and safety hazards. Mitigating these currents prevents structural degradation and equipment failure.
