Method for wirelessly testing dynamic performance of oscillating damper for train and device thereof

Abstract

The invention provides a dynamic performance wireless testing device for an oscillating damper for a train. The device comprises a sensor module, a GPS module, a data acquisition module, a wireless network transmission module, a data processing and analysis software module and the like, wherein the sensor module comprises an acceleration sensor, an infrared temperature sensor and a laser displacement sensor; data communication is carried out between the GPS module and MCU through a RS-232 serial port for obtaining information of running speed and position of the train so as to determine that indexes of the dynamic performance of the oscillating damper for the train are acquired under what working conditions, such as what speed, which position and the like; the data acquisition module simultaneously realizes acquisition of four paths of analog signals by an A / D conversion chip, including two paths of acceleration signals, a path of a temperature signal and a path of a displacement signal; the wireless network transmission module is constructed by a zigbee network so as to realize wireless data transmission and processing of dynamic performance testing of the oscillating damper for the train; and the data processing and analysis software module is used for analyzing and processing testing data of the dynamic performance indexes of the oscillating damper.

Description

Technical field [0001] The invention relates to the field of electrical detection, in particular to a wireless detection method and device for the dynamic performance of a train shock absorber. Background technique [0002] As one of the important components of the running mechanism of rolling stock, the performance of shock absorber directly affects the safety and reliability of rolling stock. Therefore, during the operation of rolling stock, it is necessary to ensure that the shock absorber can maintain reliable and stable performance. The shock absorber dynamic performance test is a test to monitor whether the various parameters of the shock absorber meet the design requirements. It analyzes the vibration reduction by testing and recording the movement of the shock absorber on the actual line. The main vibration frequency, maximum extension length, minimum compression length, temperature, vertical vibration acceleration of the axle and frame of the shock absorber on this line,...

Problems solved by technology

However, this type of test bench test system also has obvious shortcomings: the equipment requires a special working environment and strict maintenance, so it is not suitable for use in general grassroots units, and at the same time, it cannot perform performance testing of shock absorbers on actual lines
