4 core test scenarios
1. Vehicle Dynamics Testing
Perform dynamic performance testing on bogies, wheelsets, and suspension systems. Strain gauges measure frame stress, accelerometers monitor vibration response, and displacement sensors record suspension travel. The system supports a maximum sampling rate of 512kS/s, precisely capturing high-frequency transient events from wheel-rail interactions.
2. Structural fatigue testing
Perform fatigue life assessment on key structural components such as car bodies, bogies, and coupling devices. Continuously monitor stress cycle loads and predict remaining structural life using the rainflow counting method combined with Miner's cumulative damage theory. The device supports offline storage and remote data transmission to meet long-term monitoring requirements spanning several months.
3. Brake System Test
Record pressure changes, deceleration, and brake shoe temperature during braking to evaluate braking performance and safety margins. High-frequency sampling captures transient braking responses while synchronously recording data from multiple cars to analyze the uniformity of braking force distribution. Complies with UIC 544-1 braking system testing standards.
4. NVH Comfort Testing
Install microphones and accelerometers inside the cabin to evaluate passenger ride comfort. The system supports ISO 2631 human vibration exposure standards and automatically calculates comfort indices. With spectral analysis and order tracking, it identifies noise and vibration sources to guide isolation and noise reduction optimization.
