Problems solved by technology
[0003] In order to solve the problem that the frictional force between the existing lateral loading device and the fixed point on the ground is not enough to bear the reaction load generated by it, the side wall edge beam needs to bear a certain reaction load, but this situation is inconsistent with the actual force and cannot be accurately simulated To solve the technical problem of the actual stress situation of the car body, the present invention provides a universal lateral loading device for the static strength test of the car body

The present invention provides a lateral loading universal device for vehicle static strength test, and relates to the technical field of the railway carriage vehicle body static strength test devices. The lateral loading universal device comprises a left side loading mechanism, a reinforcing screw and a right side loading mechanism, the left side loading mechanism and the right side loading mechanism are the same in structure and symmetrically arranged; the left side loading mechanism comprises a support beam composition, a lower portion loading pedestal, a lower portion reinforcing rib plate, a loading support plate, a middle portion reinforcing rib plate, a bearing steel plate, an upper portion reinforcing rib plate, an upper portion loading pedestal, a loading block and a hydrocylinder. The lower portion loading pedestal is connected with a ground rack to achieve ground rack support with no need for extra installation of a counter-force tool; the reinforcing screw is connected withthe left side loading mechanism and the right side loading mechanism to easily achieve the symmetrical installation and symmetrical loading of the device, the split type structure can reduce the mutual influence of loads in different directions; the replaced loading block can achieve loading of different vehicle bodies and different positions of the vehicle bodies, and the adjustability is high;and moreover, the device is simple in structure, easy to install, convenient to operate and good in universality.
Description
Technical field [0001] The invention relates to the technical field of a static strength test device for a railway passenger car body, in particular to a transverse loading universal device for a static strength test of a car body. Background technique [0002] With the rapid development of rail vehicles, more and more attention has been paid to the operation and safety performance of the vehicles. The static strength test of the car body is a key node in the performance test of the rail passenger car, which is directly related to the safety of the vehicle operation. At present, when carrying out the static strength test of the rail vehicle body according to domestic and foreign standards, the lateral load simulation is realized by the two-way integrated test auxiliary device. The disadvantage of this test device is that the friction between the test device and the fixed point on the ground is not enough to bear its production. Reaction load, resulting in figure 1 with figure 2...
