Problems solved by technology

[0008] In order to solve the problem that the existing bogie frame strength test only loads a few frame stress nodes after mechanical simplification, it cannot fully simulate the frame under the combined forces of load, extrusion, tension, shaking, torsion, and rollover at the same time. The load-bearing state of the frame caused a large deviation between the simulated results of the test and the actual situation, and there were also certain errors in the validity of the obtained mechanical data, which could not fully reflect the real stress of the frame and brought technical problems of hidden dangers in the design. The invention provides an auxiliary loading device for bogie frame strength test

Abstract

An auxiliary loading device for a bogie frame strength test belongs to the field of auxiliary loading devices for railway vehicle bogie frame strength tests and comprises four vertical torsion load loading seats, two vertical load loading seats, two groups of nut gaskets, transverse load loading units, four braking load loading sets, two snake-shaped swing resistant load loading seats, two gear box load loading seats, two longitudinal load and transverse restrain loading beams, two motor load loading seats, vertical restraint traction bases and two testing traction pull rods. The auxiliary loading device for the bogie frame strength test has the advantages that an original arrangement space is expanded through a plurality of force bearing load loading components with expanding structures, a bogie frame strength test needs not simplify the numbers of a stress loading points, the arrangement space among every application force driving component or force bearing component is sufficient, interference and conflicts cannot occur among the every application force driving component or force bearing component, and the testing results of a simulation bogie in a dynamic comprehensive force bearing state is more accurate and reliable.

Description

technical field [0001] The invention belongs to the field of auxiliary loading devices for bogie frame strength tests of railway vehicles, in particular to an auxiliary loading device for bogie frame strength tests. Background technique [0002] Such as figure 1 with figure 2 The railway vehicle bogie shown is an H-shaped structure welded by two longitudinal beams 2, two beams 1 and side beams 3 fixedly connected to both ends of the beam 1, and each beam 1 includes a gearbox crane. Seat 1-2, motor suspension seat 1-3 and a set of traction rod seat 1-4, two seamless steel pipes 1-1 are parallel to each other, and the distance between them is bridged and fixed by two parallel longitudinal beams 2 respectively . The gear box hanger 1-2 and the motor hanger 1-3 are located on the outside of the beam 1, and a set of traction rod base 1-4 is fixedly connected above the middle section of the beam 1 and located on the gear box hanger 1-2 and the motor hanger Between 1-3. The t...
