Wheel polygon test analysis method and system

Abstract

The invention provides a polygon test analysis system. The polygon test analysis system comprises a data acquisition module for collecting data and a data processor responsible for analyzing the datacollected by equipment and obtaining an out-of-roundness curve of a wheel to be tested. The wheel polygon test analysis system is provided with a storage module for storing the acquisition data. The data acquisition module and the data processor perform wired or wireless data transmission, and the data transmission mode is WIFI or USB line transmission. The wheel polygon test analysis system is provided with a power supply module, and a battery and / or a USB cable and / or a power source are used for power supply. The wheel polygon test analysis system is further provided with a display which candisplay the out-of-roundness curve in real time. The polygon test analysis system can improve accuracy and efficiency, has good repeatability and has a low comprehensive cost.

Description

technical field [0001] The invention relates to the technical field of rail traffic safety monitoring, in particular to a wheel polygon testing and analysis method and system. Background technique [0002] With the continuous development of science and technology, the technology of rail vehicles is also changing with each passing day. It has undergone many changes from steam locomotives, diesel locomotives, and electric locomotives. Especially in modern times, high-speed rail is gradually becoming the first choice for daily travel due to its fast and comfortable. And with the development and progress of the city, the subway has become an indispensable way of travel for people's daily life, so the current rail vehicles include a variety of forms: EMUs, passenger cars, locomotives, trucks, subways and other special vehicles, but these rails The common point of vehicles is the rolling contact friction between the wheel and rail, which directly affects the dynamic performance an...

Problems solved by technology

For example, application 201310556634.0 (the out-of-roundness detection device and method of urban rail vehicle wheels based on laser displacement sensors discloses a kind of out-of-roundness detection device and method of urban rail vehicle wheels based on laser displacement sensors, the method utilizes multiple laser displacement sensors , and set a guard rail on the inner side of the rail in the detection area, the guard rail is tangent to the inner side of the wheel rim, the sensor is installed between the rail and the guard rail, and is located under the wheel, but this method is costly and requires modification of the track

And because the wheel is in the measurement, there will be a certain vibration due to contact, etc., resulting in inaccurate measurement and reducing the accuracy of measurement
