Low-friction, high-resistance-reduction, light-weight and high-strength bobsleigh device and forming method

Abstract

The invention provides a low-friction, high-resistance-reduction, light-weight and high-strength bobsleigh and a forming method. The shape of the outer surface of a shell is designed, so that the shell meets the specific curve requirement in a coordinate system. The characteristics of low friction, high resistance reduction, light weight and high strength of the bobsleigh can be achieved, in addition, through the installation of a front protective cover and a rear protective cover, the bobsleigh has better impact resistance, the shell is formed and processed by adopting a composite material through a female die forming method, the overall dimension and the profile precision of the shell are improved by combining a curing tank curing process and a vacuum bag coating process, and the bobsleigh being low in the friction, high in the resistance reduction, light in weight, high in strength and high in reliability is achieved.

Description

technical field [0001] The invention relates to a device and a molding method, in particular to a streamlined structure using composite materials and a molding method. Background technique [0002] Fiber-reinforced composite materials are widely used in the field of sports equipment because of their outstanding light weight, high strength, and designability, and are favored by sports enthusiasts. The application of fiber-reinforced composite materials in sports equipment mainly includes plate structures (skis, surfboards, windsurf boards, etc.), tubular structures (tennis rackets, badminton rackets, ice hockey sticks, etc.), thin sheet structures (hull structures of helmets, boats, etc.) etc.), others (bicycles, sword hilts, climbing ropes, etc.), the current application of fiber-reinforced composite materials in sports equipment is in the field of simple, rapid manufacturing, and low cost. The application on the steering sled has not been reported. The main reason is the l...

Problems solved by technology

[0005] A bobsleigh (also known as a bobsleigh) is a high-end sports equipment, shaped like a small boat, with a streamlined cover on the front, and the bobsleigh runs like lightning during the race Gliding at high speed, the main factors affecting the sliding speed are weight, air resistance, and friction. The current bobsled is mainly made of steel, aluminum alloy and other metals. The heavy body and high air resistance limit the speed of the bobsled. Sliding affects the performance of athletes and the appreciation of events. Therefore, it is urgent to develop a low-friction, high-drag reduction, light-weight and high-strength bobsled to greatly increase the sliding speed of the bobsled, improve the performance of events, and ensure that Chinese athletes can compete in major sports. Excellent results in competitions (Olympics, World Cup, World Championships, etc.)
