(1) there is geometric catastrophe in the cross section of junction, and framework overall stress cannot evenly be transmitted, and there will be stress and concentrate situation, belongs to framework load-carrying capacity weak area;
(2) for meeting the requirement of strength of this join domain, need carry out comparatively complicated structure design and welding design, thus, the manufacturability in this region requires higher;
(3) on framework, the actuating device of larger quality is directly installed on crossbeam place, and its frequent operation state causes the force-bearing situation of this join domain very harsh, causes this join domain to belong to anti-fatigue performance thin spot in the framework military service phase.
Also have a kind of EMU power steering truck frame work, its technical characteristics is that the crossbeam of box-structure is connected by intermediate configuration with curb girder, and namely intermediate configuration side is connected with crossbeam, and opposite side is connected with curb girder.Other functional details are welded in crossbeam and two curb girders respectively.Following problem is there is in the framework of this kind of structure in the connection of crossbeam, curb girder and intermediate configuration:
(1) the multiple tracks attachment weld of every side is in close region, and cause the strength grade in this region seriously on the low side, therefore this join domain belongs to the stressed weakness zone of framework; Therefore the degree of quality of weld seam requires higher, belongs to the high risk area in the framework military service phase simultaneously;
(2) intermediate configuration rigidity is bigger than normal, when causing framework stand under load, the stress of crossbeam and curb girder can not evenly transmit, must form area of stress concentration in its vicinity, bear higher stress with therefore causing the large density of neighbouring attachment weld, the fatigue property of butt welded seam is very unfavorable.
Summary of the invention
The object of this invention is to provide a kind of EMU power steering truck frame work of low stress, to be connected with curb girder variable section and the stress in this region is concentrated to solve crossbeam, simultaneously by the particular design of weld seam, make the stress level of each parts attachment weld on framework relatively low, present good anti-fatigue performance and the safety of this framework.
