Absorber sealing quality detection device

Abstract

The invention provides an absorber sealing quality detection device. 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; the GPS module communicatesdata with an MCU through an RS-232 serial port and is used for acquiring the operation speed and position information of a train, thus, under what working conditions such as speed, position and the like the dynamics performance indexs of a train absorber are obtained can be determined; the data acquisition module acquires 4 ways of simulation signals, including two ways of acceleration signals, one way of temperature signal and one way of displacement signal, simultaneously by use of an A / D conversion chip; the wireless network transmission module is constructed by a zigbee network to realizewireless data transmission and processing for dynamics performance detection of the absorber; the data processing and analysis software module is used for analyzing and processing test data of the dynamics performance indexes of the absorber.

Description

technical field [0001] The invention relates to the technical field of automobile shock absorber assembly tools, in particular to a shock absorber sealing quality detection device. Background technique [0002] Shock absorber is one of the important components of rolling stock running mechanism, and its performance directly affects the safety and reliability of rolling stock operation. Therefore, it is necessary to ensure that the shock absorber can maintain reliable and stable performance during the operation of the rolling stock. The dynamic performance test of the shock absorber is a test to monitor whether the various parameters of the shock absorber meet the design requirements during work. It analyzes the shock absorber by testing and recording the movement of the shock absorber on the actual line. The main vibration frequency, maximum stretching length, minimum compression length, temperature, vertical vibration acceleration of the axle and frame of the shock absorbe...

AI Technical Summary

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
