Latest Patents
Xin Chen holds a patent titled "Reference-free load-modulated longitudinal rail stress measurement using ultrasonic LCR waves." This patent describes a method for in situ measurement of an acoustoelastic constant (L) of a railway rail. The process involves using an ultrasonic wedge sensor to measure a stress-free time-of-flight in the vertical direction of the rail. After applying a known vertical load to the rail, the sensor measures the stressed time-of-flight value. The difference between the stress-free and stressed time-of-flight is calculated to obtain a time-of-flight difference value (Δt). This method allows for the calculation of the acoustoelastic constant, L, which is crucial for understanding the stress conditions of railway rails.
