Problems solved by technology

Among them, the first and second types of car body skirts can meet the requirements of rigidity, strength, impact, fire protection, and service life, but their weight is relatively large, which is not conducive to achieving the goal of lightweight; the third type of car body skirt with sandwich sandwich structure exists The core material is sensitive to water vapor, the interface connection strength between the core material and the skin is not high, or due to the limitation of the compressive strength of the core material, the mechanical properties of the formed skin are low, which leads to problems such as skin damage resistance, which affects the use life

Abstract

The invention relates to a railway vehicle and a vehicle body apron board of the railway vehicle. The vehicle body apron board of the railway vehicle comprises an apron board body, and the apron boardbody is an integrally formed carbon fiber composite material; and the apron board body comprises an outer skin, an inner skin, a shaft hole part and a vertical rib set, the shaft hole part and the vertical rib set are arranged between the outer skin and the inner skin, the vertical rib set can form a multi-cavity structure between the outer skin and the inner skin, and the shaft hole part is located at an end of one side of the multi-cavity structure. The vehicle body apron board can meet requirements for rigidity, strength and a service life, and meanwhile a light weight target can be achieved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle and its car body skirt. Background technique [0002] In order to reduce the running resistance and noise of the rail vehicle, skirts are installed on the side of the car body, which can resist snow and ice, prevent sundries from impacting equipment under the car, and prevent dirt, rain and snow from accumulating under the car. [0003] There are three main types of existing car body skirts, the first is the car body skirt made of lightweight aluminum alloy material, the second is the car body skirt with rib structure, and the third is the car body skirt with sandwich sandwich structure plate. Among them, the first and second types of car body skirts can meet the requirements of rigidity, strength, impact, fire prevention, and service life, but their weight is relatively large, which is not conducive to achieving the goal of lightweight; the third type of ca...
