Abstract

The invention discloses a bogie steering resistance moment measurement test bench. The test bench comprises auxiliary lifting mechanisms, an electro hydraulic servo system, a steering resistance moment measurement platform, a rotation shaft, a transverse positioning mechanism assembly and a lower fixed platform, four sets of auxiliary lifting mechanisms lift the steering resistance moment measurement platform, the auxiliary lifting mechanisms are fixed on a test bench counter-force seat fixing platform and connected with the steering resistance moment measurement platform through a lifting pull rod, two longitudinal actuators in the electro hydraulic servo system are in a hinged connection with a test bench base and the steering resistance moment measurement platform, the rotation shaft and the transverse positioning mechanism assembly are fixed on the lower fixed platform, simultaneously the upper portion of the test bench is connected with the steering resistance moment measurement platform through an expansion type sliding block, and thereby the transverse positioning of the test bench is achieved. By means of the bogie steering resistance moment measurement test bench, the steering resistance moment measurement is achieved in states of full vehicle completion and bogie completion simulated vehicle weight during the test, simultaneously the bogie steering resistance coefficient can be determined, and thereby the vehicle can be evaluated.

Description

technical field [0001] The invention relates to testing equipment in the field of rail vehicles, in particular to a test bench for measuring swivel resistance torque of a bogie. Background technique [0002] The bogie is a key component of a rail vehicle, especially in high-speed EMU technology, its performance parameters directly affect the running quality of the vehicle, and directly determine the dynamic performance, operating safety and driving stability of the vehicle. Slewing resistance torque is an important dynamic parameter of the bogie, which directly affects the dynamic performance of the bogie and is related to the running quality of the train. If the turning torque is too large, the train will derail due to the large gauge tension when passing through the curved track; if the turning moment is too small, the vehicle will shake its head and snake-like movement during operation, which will affect the stability of the vehicle running. [0003] At present, there is...
