Problems solved by technology
[0003] At present, during the static strength test of the car body, when testing the installation position of small-mass components such as side windows, the side window load is simply distributed evenly on the structural floor of the car body, and the actual installation position and installation position are not followed. Simulated in different ways, resulting in the discrepancy between the simulated state of the above parts and the actual load state, which affects the accuracy of the static strength test of the car body and causes errors in the test results

The invention provides a side window simulation device for railway vehicle body detection. The side window simulation device comprises a frame, a mounting rack and a counterweight assembly, the frame is used for being embedded in a window frame. The mounting rack is arranged in the middle of the frame; the end part of the mounting rack is connected with the inner peripheral wall of the frame; and the counterweight assembly comprises a plurality of counterweight pieces which are respectively arranged on two side surfaces of the mounting frame and are used for simulating the load of the vehicle window. According to the railway vehicle body detection side window simulation device, the frame is installed in the window frame, the installation frame is arranged in the middle of the frame, the counterweight assembly is installed by means of the installation frame, it is guaranteed that the load is applied to the middle of the window frame, and the structure can accurately simulate the load state of the side window portion of the vehicle body through the counterweight assembly; the real simulation of the vehicle body load condition in the actual operation state is realized, the static strength test of the vehicle body is assisted, the accuracy of the test result is ensured, and the effectiveness of the test detection is improved.
Description
technical field [0001] The invention belongs to the technical field of rail vehicle body detection, and more specifically relates to a rail vehicle body detection side window simulation device. Background technique [0002] The static strength test of the car body is a mandatory type test item for rail transit vehicles. The purpose is to check whether the strength and stiffness design of the car body of the rail vehicle meets the requirements. Since the opening of the side windows of rail vehicles has a great impact on the car body structure, the car body structure near the side windows is prone to insufficient structural strength or rigidity, and is one of the key monitoring parts of the static strength test of the car body. [0003] At present, during the static strength test of the car body, when testing the installation position of small-mass components such as side windows, the side window load is simply distributed evenly on the structural floor of the car body, and th...
