Ground vehicle load simulation implementation device in physical model test

Abstract

The invention relates to the field of vehicle test equipment, in particular to a ground vehicle load simulation implementation device in a physical model test, which comprises a driving assembly, a linkage assembly meshed with the driving assembly and a vehicle load applying assembly arranged on the linkage assembly. The driving assembly comprises a driving part and two fluted discs arranged at the output end of the driving part, and the axial distance between the two fluted discs is adjustable. The linkage assembly comprises gears meshed with the two sides of each fluted disc, the axial distance between the two coaxial gears can be adjusted, the outer sides of every two gears located on the same plane are sleeved with a chain, and the chains are connected with the vehicle load applying assembly. A weight adjusting part is arranged on the outer side of the vehicle load applying assembly, and a wheel simulation device is arranged at the end, away from the chains, of the vehicle load applying assembly. The invention provides a ground vehicle load simulation implementation device which is used in a physical model test and can be adjusted according to actual vehicle wheel track, wheel base, wheel set single axle load, vehicle running speed and vehicle flow.

Description

technical field [0001] The invention relates to the field of vehicle test equipment, in particular to a ground vehicle load simulation implementation device in a physical model test. Background technique [0002] In the catastrophic process of urban road and surrounding engineering geological disasters, the ground vehicle load is one of the disaster-causing factors that must be considered. Indoor physical model test is a main research method for the research on the mechanism of such engineering geological disasters. According to the similarity theory, the surrounding environment and disaster-causing factors during the occurrence of actual engineering geological disasters can be reproduced in the laboratory through physical model tests, and the experimental data obtained through monitoring can intuitively reflect the occurrence process of disasters. Compared with the field test, the physical model test has the advantages of low cost, simple operation, and strong parameter co...

Problems solved by technology

[0003] However, in this type of physical model test, the ground vehicle load is usually simplified to a uniform surface load with a certain frequency and load size. In reality, the actual vehicle load is based on the contact surface between each wheel and the road surface, and the vehicle The wheelbase and wheelbase are much larger than the size of the contact surface, so there is a big difference between the current ground vehicle load simulation implementation method and the actual vehicle load application method, and it is difficult to truly reflect the actual situation, resulting in the vehicle load in this type of project. The research results of the disaster-causing mechanism in the process of geological disaster catastrophe are relatively inaccurate
