Description

technical field [0001] The invention belongs to the technical field of rail transit, and more specifically relates to an online dynamic measurement device and method for measuring wheel rim parameters of a rail transit wheel. Background technique [0002] With the rapid development of my country's rail transit, the safety issues of train running online are becoming more and more obvious. The wheelset is the part of the train that comes into contact with the rails. The wheel set ensures the running and turning of the locomotive on the rails, bears all the static and dynamic loads from the train, and transmits it to the rails, and transmits the load caused by the unevenness of the line to the components of the train vehicle. In addition, the driving and braking of train vehicles also work through the wheelset. Therefore, the condition of the wheel set is directly related to the running quality and safety of the train, and the real-time monitoring of its size parameters is an...
