Method and device for manufacturing ultra su00c8nicos tensions in railway wheels

摘要

Method and device for manufacturing ultra su00c8nicos tensions in railway wheels the present invention is a system for measuring voltages of manufacture in railway wheels, based on the measurement of the transit time of ultrasonic waves longitudinal critically petrographic S. the system is composed of commercial equipment, program control and automation and mechanical assembly.The facilities are: computer acquisition board 20 MHz or higher, the plate normal signal acquisition, conditioning and heat detectors and force (or pressure), a push button receiver, a set of transduction, system for force control system for control of the temperature and System for fixing on the wheels.One of its advantages is to be the first set capable of determining mechanical stresses in the rail wheels new without damaging them, being of easy use and low cost. The results of measurements with the system shall include the effects of temperature, the strength of the application and the variation of texture, which is not yet done by other systems, non-destructive for stress measurement.
