Embodiment Construction

[0034] The present invention is described in detail below in conjunction with accompanying drawing:

[0035] The purpose of the present invention is to provide a high-speed EMU drive train assembly reliability test bench to meet the needs of reliability parameter detection of rail vehicle drive systems under various operating conditions. The test bench adopts a reasonable structural design of the load simulation system, which can simulate the vibration conditions of three degrees of freedom and three degrees of freedom coupling, that is, accurately simulate the vibration state of rail vehicles running on the road, thus ensuring the transmission of high-speed EMUs. The correctness and authenticity of the test results of the system reliability parameters. All the tests are destructive tests, so that the reasons for the destruction of the tested drive train and the specific technical parameters can be accurately given. Researching the reliability of high-speed EMU drive train ha...

Abstract

The invention discloses a high-speed train transmission system assembly reliability test bed. The test bed comprises a power transmission flexibility test device, a three-degree-of-freedom vibration simulation test device, and a high-speed train transmission system assembly reliability test device. The three-degree-of-freedom vibration simulation test device and the high-speed train transmission system assembly reliability test device are mounted on the foundation in parallel; a crossbeam of the three-degree-of-freedom vibration simulation test device and a high-speed train transmission system assembly support platform of the high-speed train transmission system assembly reliability test device have a parallel distance of 20 to 40 mm; and the upper work surface of the crossbeam and the upper work surface of the high-speed train transmission system assembly support platform are on the same horizontal plane. The three-degree-of-freedom vibration simulation test device is connected with the power transmission flexibility test device mounted on the foundation through a transverse actuator; and the power transmission flexibility test device is connected with the high-speed train transmission system assembly reliability test device through a cross-shaft type universal coupling.

Description

technical field [0001] The invention relates to a test device for detecting and testing parameters of a rail vehicle drive train, and more specifically, the invention relates to a reliability test bench for a drive train assembly of a high-speed EMU. Background technique [0002] In recent years, my country's EMU technology has developed rapidly. Through six major speed increases, more than 160 sets of "Harmony" high-speed trains with a speed of 200km / h and above have been operated on the main trunk lines in the Bohai Rim, the Yangtze River Delta, and the Pearl River Delta. The operating speed of some sections reaches 250km / h. In 2008, the Beijing-Tianjin intercity high-speed train was successfully launched, and the maximum operating speed was increased to 330-350km / h. h, the maximum speed of the EMU under development is close to 500km / h. With the increase of the train speed and the aggravation of the vehicle axle load, the vibration between the vehicle and the track is inten...
