Railway vehicle model

Abstract

The invention discloses a railway vehicle model which can visually display the transfer relation of connection and forces between a vehicle body steel structure of a railway vehicle and all parts and can be used for reverse engineering teaching and deducing the mechanical property correspondence between the model and the true vehicle structure. The railway vehicle model comprises a steel structural simulated vehicle body and a vehicle fixing device, wherein a simulated bogie is arranged at the bottom of the simulated vehicle body; and a force applying device and a force testing system are respectively arranged on the simulated vehicle body and the simulated bogie. The railway vehicle model can be used for structural function display or exhibition and leads students to obtain visual perceptual knowledge; simultaneously can be used for scientific researches such as deducing of mechanical property correspondence between a similar model and the true model, can visually display the transfer relation of connection and forces between all parts of the railway vehicle, can analyze transfer of forces in all the directions through the force testing system; and is suitable to popularize and use in the teaching and scientific research device fields.

Description

technical field [0001] The invention relates to the field of teaching and scientific research equipment, in particular to a railway vehicle model. Background technique [0002] Railway passenger car is an important tool for transporting passengers, and the design and manufacturing process of its main load-bearing components are related to the comfort and safety of passengers. For teaching units such as railway-related colleges and universities, higher vocational colleges, secondary vocational schools, and railway training institutions, railway vehicle models are of great significance in the teaching process. [0003] At present, most of the various railway vehicle models used in China are made of plastic or plastic steel products. Teaching contents such as load-bearing structure, beam section type, welding process, bearing capacity, vibration mode, anti-collision structure, and impact energy transfer of main components of railway vehicles are mainly explained through books....

AI Technical Summary

Problems solved by technology

Book teaching has difficulties in teaching related experiments such as structural force, process analysis, and reverse engineering. Students cannot deeply understand the important role of the main force-bearing parts of the vehicle, and the existing railway vehicle models are difficult to use for similar applications due to material and structure limitations. Scientific research work such as the derivation of the relationship between mechanical properties between the model and the real model cannot intuitively display the connection and force transmission relationship between the various parts of the railway vehicle, and cannot analyze the transmission of forces in various directions. Even if the existing railway vehicle model It is made of steel structure, and many structures have been simplified. Even for the convenience of production, many deformation designs have been carried out after the original structure has been scaled down. It is impossible to carry out reverse engineering teaching and deduce the corresponding relationship between the mechanical characteristics of the model and the real vehicle structure. Wait
