Abstract

The invention relates to a simulation test bed for a straddle type monorail single-shaft bogie. The simulation test bed comprises walking rollers, a bearing table, a base platform and a positioning pull rod, wherein the walking roller can be rotatably installed in the bearing table and is used for cooperating with a walking wheel of a bogie to be tested and driving the walking wheel to rotate. The bearing table is installed on the base platform through a vibration excitation unit capable of driving the bearing table to excite vibration. A support unit capable of adjusting the freedom degree of the base platform is installed below the base platform. The positioning pull rod is installed on the upper portion of the bearing table and used for adjusting the posture of the bearing table. Compared with the prior art, the test bed can simulate the postures of the bogie when the bogie operates under different working conditions, can also perform multi-directional vibration excitation on the single-axle bogie through the vibration exciter to determine the random response frequency of the single-axle bogie, and can effectively verify the related performance of the bogie and judge whether the bogie can normally and safely operate or not.

Description

technical field [0001] The invention relates to a detection device for a bogie, in particular to a simulation test bench for a straddle-type monorail single-axis bogie. Background technique [0002] With the rapid development of the country's economy and society, the urbanization process is accelerating, resulting in serious pollution of the urban environment, traffic congestion, and hindering the further development of the city. Only the development of traditional public transportation cannot solve this problem, especially in cities with large mountainous areas such as Chongqing, it is difficult to continue to develop road transportation, so many cities are looking for public transportation with large capacity, less land occupation and less pollution. Urban rail transit has become the first choice to solve traffic pollution and congestion problems. [0003] Straddle-type monorail transit is a form of urban rail transit. It is built on elevated roads, occupies less land, is...
