A double u-shaped buffer support and its manufacturing method

Abstract

The invention discloses a double-U type buffering support and a manufacturing method of the double-U type buffering support. The double-U type buffering support comprises double-U type components. Each double-U-type component comprises a U-shaped component and a reversed-U-shaped component, wherein one open end of the U-shaped component and one open end of the reversed-U-shaped component are connected, the length of the connected side of the double-U type component is larger than the sum of lengths of the open sides of the double-U type component, the connected side of the double-U type component is fixedly connected to the outer side of a first circular ring, the open end of the reversed-U-shaped component is fixedly connected to the inner side of a second circular ring, and the open endof the U-shaped component is fixedly connected to the inside of a third circular ring. The invention further discloses a manufacturing method of the double-U type buffering support. According to the manufacturing method, steel is cut into steel strips with different lengths, widths and thicknesses, the steel strips are bent into the reserved-U-shaped components, the U-shaped components and three different circular rings, each reserved-U-shaped component and each U-shaped component are welded into the double-U-shaped component, and then the circular rings and the double-U-shaped components arewelded into the double-U type buffering support. The double-U type buffering support has the advantages of being large in buffering deformation travel, high in impact bearing capacity and reusable.

Description

technical field [0001] The invention belongs to the technical field of impact protection engineering structures, and relates to a double U-shaped buffer support and a manufacturing method of the double U-shaped buffer support. Background technique [0002] With the advancement of science and technology, the number of various vehicles, ships, and aircraft is increasing, and the speed is getting faster and faster, and the collision accidents are also increasing. The main way to solve the collision accidents is to improve the crashworthiness of the structure itself and A protective device with good energy-dissipating cushioning properties. [0003] The traditional load-bearing structure only undergoes small elastic deformation under the working load, while the energy-absorbing structure can withstand short and strong dynamic loads such as impact and explosion, so the design and analysis of the energy-absorbing structure and the traditional load-bearing structure are obviously d...
