Subway Design To Apply For Fastener Stiffness Detection Patent, Greatly Improve The Efficiency Of Fastener Stiffness Detection

On February 27, 2024, according to the announcement of the State Intellectual Property Office, Guangzhou Metro Design and Research Institute Co., Ltd. applied for a project entitled "A fastener stiffness detection method, device, equipment and storage media", the public number CN117606925A, the application date is November 2023. The patent abstract shows that the invention discloses a method, device, equipment and storage medium for detecting fastener stiffness. The method comprises: obtaining vehicle parameters and track parameters of the line to be detected; Obtain the wheel-rail vertical force of the line to be detected, and calculate the fundamental frequency of the wheel-rail coupling system according to the vertical force of the line to be detected. The vehicle parameters, track parameters and the base frequency of the wheel-rail coupling system of the line to be tested are input into a preset fastener stiffness prediction model, so that the fastener stiffness prediction model can predict the fastener stiffness of the detection line according to the vehicle parameters, track parameters and the base frequency of the wheel-rail coupling system, and output the predicted fastener stiffness of the line to be tested. The invention can greatly improve the detection efficiency of fastener stiffness, and significantly reduce the manpower and material resources required for fastener stiffness detection.
