Abstract

The invention provides an automatic forming method of a high-speed rail composite material vehicle body. The method comprises the following steps of (1) firstly carrying out partition treatment on a cylindrical section of the vehicle body, and dividing the vehicle body into a multi-cavity carbon fiber composite material structure with different section shapes; (2) carrying out pultrusion molding on the multi-cavity carbon fiber composite material for a high-speed rail through pultrusion equipment; (3) positioning and gluing adjacent high-speed rail vehicle body composite material assemblies through a positioning and clamping tool; (4) carrying out winding through a forming device for winding a reinforcing layer, and completing forming of the reinforcing layer in the blank direction and +/-45-degree direction in the length direction of the high-speed railway vehicle body assemblies ; (5) adopting a shot blasting surface treatment mode; and (6) coating and spraying the surface of the carbon fiber composite material high-speed railway vehicle body. Automatic vehicle body integration and automatic forming are achieved, the number of connecting pieces is greatly reduced, and the reliability, safety and comfort of the vehicle body structure are guaranteed, and automatic forming of the high-speed railway vehicle body is completed.

Description

technical field [0001] The invention relates to the field of automatic forming of carbon fiber composite materials, in particular to an automatic forming method for a high-speed rail composite material vehicle body. Background technique [0002] The high-speed EMU car body can be regarded as a cylindrical overall load-bearing structure. At present, most of the car bodies of high-speed EMUs adopt a full-load aluminum alloy structure. The alloy extruded profiles are tailor-welded, and the various components are welded and connected. This full load-bearing aluminum alloy car body bears all the loads during the operation of the high-speed EMU. For the high-speed EMU, the performance of the car body stiffness directly affects the safety, reliability and comfort of the EMU car body. and other key indicators. [0003] At present, the traditional structure trains made of metal materials increase the difficulty of solving the problems of vibration, impact, resistance and noise whi...
