Example Embodiment

[0042] The present invention will be described in detail below in conjunction with the drawings:

[0043] The invention provides a six-degree-of-freedom simulation loading test bench for a monorail train bogie, so as to meet the requirements of reliability parameter test of the monorail train bogie under actual operating conditions. The test bench is designed with a test simulation car body, which can truly simulate the mass and mass distribution of the semi-cars. It uses 7 actuators to effectively simulate the vibration conditions of six degrees of freedom and six degrees of freedom, that is, to accurately simulate monorail trains. The actual operating vibration conditions of the bogie ensure the correctness and authenticity of the reliability parameter test results of the monorail train bogie. Research on the reliability of monorail train bogies has high social value and broad social significance. It has a very good role in improving the safe operation of monorail trains, impro...

Abstract

The invention relates to a six-degree-of-freedom simulation loading test bench for a bogie of a monorail train, which is composed of a car body restraint truss, a six-degree-of-freedom excitation test device and a test simulation vehicle body. The six-degree-of-freedom excitation test device consists of a vibration excitation device, 1, No. 2 guide wheel driving device, running wheel driving device and stabilizing wheel driving device, the test simulation body and the test bogie are fixed together, and are located on the six-degree-of-freedom excitation test device as a whole, so that the running wheel of the test bogie , the stabilizing wheel and the guiding wheel are respectively in frictional contact with the driving roller of the traveling wheel, the driving roller of the stabilizing wheel and the driving roller of the guiding wheel. The invention overcomes the problem that the monorail train bogie cannot be tested for bogie parameters in actual operation and there is no record for the parameter test equipment of the monorail train bogie. It can accurately simulate the vibration of the monorail train bogie in actual operation, so that the test data is more correct and authentic, and the test results are more real and reliable.

Description

technical field [0001] The invention relates to a monorail train bogie parameter detection test device, more specifically, the invention relates to a monorail train bogie six-degree-of-freedom simulation loading test bench. Background technique [0002] The world's first straddle-type monorail railway line was born in Ireland in 1888. The line is about 15km long, pulled by steam locomotives, with a maximum speed of 43km / h and a travel speed of 29km / h. The technology of straddle-type monorail railway began to receive people's attention after the Second World War, and gradually improved and matured. [0003] With the rapid development of social economy and the advancement of urbanization, urban traffic is facing enormous pressure, especially in medium and large cities, the existing traffic system has gradually become one of the bottlenecks of sustainable economic development, the development of urban The rail transit system is an effective solution. Monorail traffic, like li...
