Wayside Angle of Attack Measurement System
AOAView is a wayside angle-of-attack (AOA) measurement system that integrates with AEI for vehicle identification and reporting. AOAView is designed to measure AOA of both wheels of a wheel set simultaneously. Since AOAView is installed on a tie (sleeper) between the rails, it provides a reliable AOA measurement as track fluctuations due to dynamic loads do not affect where the measurements are performed (the system moves with the track). Moreover, AOAView provides extremely accurate measurements of back-to-back distance of wheel sets.
Tracking position and axle back to back measurements are other parameters that this system is capable of measuring. The system is installed between the rails and has sufficient clearance with respect to the rail for most rail grinding machines and other track maintenance equipment to pass through the location without interference.
