Wheel/rail contact geometry inspection

摘要

Management Strategic Research Initiative (SRI), automated inspection of wheel/rail contact geometry is one of four major tasks in the SRI 1A project. The objective is to improve the life of wheels and rails and vehicle per-formance through controlled wheel and rail profiles; improved safety; reduced wheel/rail profile-caused derailments; improved efficiency; significantly increased wheel/rail contact inspection efficiency and improved rail maintenance by identifying the problems and prioritizing the needs.
