Abstract

The invention provides a lightweight maglev train driver's cab cover and an integral molding process thereof. This kind of lightweight maglev passenger car driver's cab cover includes a cover body, and the cover body includes a right side cover plate, a front cover plate, a coupler cover plate, a left side cover plate and a bottom cover plate, and the cover body is made of glass fiber and carbon fiber. It is made of hybrid fiber composite material with reinforcement and thermosetting resin as the matrix. And by using the split combination mold of the above five parts, the traditional train driver's cab and the shroud are integrally formed. The formed hybrid fiber composite cab is more than 30% lighter than the current FRP cab, and has high strength, high damage tolerance, low notch sensitivity, and impact resistance, flame retardancy, corrosion resistance, aging and Excellent fatigue properties.

Description

technical field [0001] The invention relates to a light-weight maglev train driver's cab cover and an integral molding process. Background technique [0002] Maglev trains are divided into two types: medium-low speed and high-speed. The medium-low speed maglev is mainly used for short-distance rail transit such as urban rail transit, with a speed of 80-150 kilometers per hour. my country built the first medium and low-speed maglev train in Shanghai in 1992. At present, the driver's cab made of aluminum alloy or fiberglass is basically used. In recent years, maglev technology has entered a stage of rapid development. Under the concept of "energy saving and environmental protection" advocated globally, it is required to reduce the weight of trains to achieve lower energy consumption and stronger transportation capacity, while ensuring the safety and security of the operation process. Longer life of operation. [0003] Therefore, it is necessary to solve the problem of light ...
