Wagon bogie swinging rigidity online detection device and method

Abstract

The invention discloses a wagon bogie swinging rigidity online detection device and method. The wagon bogie swinging rigidity online detection device comprises an industrial control computer, a data processor, a vertical loading actuator, a movement platform, a wheel pair clamping actuator, a horizontal loading actuator, a first displacement sensor and a fourth displacement sensor, wherein the vertical loading actuator is arranged at the top of a wagon bogie and used for exerting the vertical testing pressure on the wagon bogie, the movement platform is arranged at the bottom end of the wagon bogie and used for containing the wagon bogie, the wheel pair clamping actuator is arranged on the movement platform and used for clamping a wheel pair of the wagon bogie, the horizontal loading actuator is arranged on one side of the movement platform and used for exerting the horizontal transverse pushing force on the movement platform, the first displacement sensor is arranged at the position of a lower swinging point of a side bogie body of the wagon bogie, and the fourth displacement sensor is arranged on the triangular hole side of a square frame in the middle of the side bogie body of the wagon bogie. According to the wagon bogie swinging rigidity online detection device and method, online real-time detection can be carried out on the swinging rigidity of the swinging type wagon bogie, and guaranteeing of the safety performance when each wagon bogie runs is facilitated.

Description

technical field [0001] The invention relates to the technical field of railway freight car parameter detection, in particular to an online detection device and method for the swing stiffness of a railway freight car bogie. technical background [0002] The performance parameters (including the swing stiffness) of the railway freight car bogie are important indicators to ensure that the dynamic performance of the speed-up heavy-duty freight car meets the specification requirements. At present, the detection of the swing stiffness parameters of the railway freight car bogie is carried out in the laboratory. [0003] The existing methods are to test the samples of railway freight car bogies in special laboratories. However, due to the discreteness of parts processing size, material and structure assembly of railway freight car bogies, the performance parameters are discrete, and the power of freight cars is greatly affected. academic performance is greatly affected. The detec...

Problems solved by technology

[0003] The existing methods are to test the samples of railway freight car bogies in special laboratories. However, the discreteness of performance parameters due to the discreteness of parts processing size, material and structure assembly of railway freight car bogies has great impact on the power of freight cars. have a great influence on academic performance

The detection of railway freight car bogie samples cannot completely and accurately characterize the swing stiffness of each railway freight car bogie, which makes the railway freight car bogie have certain safety hazards in operation

At present, there is no simple and reliable detection method for on-line detection and comprehensive quality control of the performance parameters of the truck bogies produced in batches. This is a deficiency in the current production of trucks and needs to be improved urgently.
