At present, the steel structure of all luggage carts in my country adopts the overall load-bearing thin-walled cylindrical structure with a center beam, that is, the underframe has a strong through-type center beam, and the cross-sectional dimensions of the side beams and the bolster beams are smaller than those of the center beam. , There are several large beams and a large number of small beams connected with the middle and side beams.
Because there is a center beam, and the center beam bears most of the longitudinal force and part of the vertical load, the load-bearing capacity of the side walls and roof members is not fully utilized and utilized. The static strength test results of the car body also show that the center beam has a strong load-bearing capacity, and there is generally no problem with the strength during the test. The side beams are less stressed, and the local beams will have insufficient strength. The end beams and side walls mainly transmit longitudinal forces, and the side columns actually Does not bear the vertical force, and the roof of the car basically does not bear the load.
