Comprehensive simulation test system for railway hopper car

Abstract

The invention relates to a comprehensive simulation test system for a railroad hopper car. The test system comprises an orthogonal six-degree-of-freedom excitation platform, a simulated hopper car bin, a bottom door opening and closing mechanism, a longitudinal load simulation loading mechanism and a material circulating system, wherein the simulated hopper car bin is installed at the upper end of the orthogonal six-degree-of-freedom excitation platform, the orthogonal six-degree-of-freedom excitation platform is provided with a discharge port opposite to the simulated hopper car bin, the bottom door opening and closing mechanism is connected with a bottom door of the simulated hopper car bin, the bottom of the longitudinal load simulation loading mechanism is vertically fixed on the orthogonal six-degree-of-freedom excitation platform, and the top of the longitudinal load simulation loading mechanism is connected with an end wall of the simulated hopper car bin. The material circulating system and the simulated hopper car bin are opposite to the discharge port of the orthogonal six-degree-of-freedom excitation platform. The test system can accurately simulate the real test environment of the hopper car and accomplish functional simulation test, vibration test and material circulating test of the hopper car.

Description

technical field [0001] The invention relates to a funnel car test device, in particular to a railway funnel car comprehensive simulation test system. Background technique [0002] At present, there are relatively few test methods for railway hopper cars at home and abroad, and the technology is backward. According to the standard AAR S-233-2014 of the Association of North American Railroads, "Technical Conditions for New Gravity Unloading Ports of Covered Hopper Cars". Taking the core components of the funnel car (bottom door and opening and closing mechanism) as the research object, it is necessary to complete the function simulation test, vibration test, material circulation test, sealing test and bottom door opening and closing of the railway funnel car bottom door and opening and closing mechanism. Mechanism cycle test and many other comprehensive tests, while the existing test methods and test devices cannot complete functional simulation tests, vibration tests and mat...

AI Technical Summary

Problems solved by technology

Moreover, the software analysis method can only simulate some tests of the hopper car, such as the strength test, but cannot analyze and simulate the live operation of the hopper car, such as vibration conditions, material circulation conditions, and bottom door opening and closing conditions, etc.
