Problems solved by technology

According to the design experience and the statistical results of the crash test, if the front longitudinal beam is too thin, the collapse mode is not ideal, and if it is too thick, it is easy to cause the front longitudinal beam to bend during the collision
The traditional design of the front longitudinal beam based on high-strength steel cannot satisfactorily coordinate the contradiction between high energy absorption, low peak collision acceleration and good crush mode in the process of crash safety design

Embodiment Construction

[0015] The following description is merely exemplary in nature and not intended to limit the disclosure, application or use.

[0016] refer to Figure 4-6 , the structure of the patent square tapered aluminum alloy car front longitudinal beam has three parts: aluminum alloy outer wall 1, carbon fiber reinforced plate 2 and aluminum alloy tail plate 3. The assembly process is as follows: first produce the aluminum alloy outer wall 1, carbon fiber reinforced plate 2 and aluminum alloy tail plate 3, then install the carbon fiber reinforced plate 2 from the tail end of the aluminum alloy outer wall 1 formed into a square surround, and finally put the tail plate 3 Welded to the tail of the aluminum alloy outer wall 1, thereby completing the manufacture of the front longitudinal beam.

[0017] The following is the manufacturing process for the three parts:

[0018] The manufacturing process of the aluminum alloy outer wall 1: Since there are not many applications of aluminum alloy...

Abstract

The invention relates to a square tapered aluminum alloy automobile front carling based on an embedded carbon fiber. The square tapered aluminum alloy automobile front carling based on the embedded carbon fiber is characterized in that the section of the front carling is composed of two parts, namely the aluminum alloy outer wall and a carbon fiber reinforced plate. An aluminum alloy outer plate is little in elasticity modulus and good in deformation mode and the carbon fiber reinforced plate has the strong collision energy absorption capability. By means of the two new materials are combined and a square tapered structure, the contradiction among the high energy-absorption performance, the low-collision-acceleration peak value and the good crushing mode can be coordinated in a satisfying manner in the collision safety design process. The square tapered aluminum alloy automobile front carling based on the embedded carbon fiber has great significance in improvement of the collision performance and weight reduction.

Description

technical field [0001] The invention relates to the technical field of front longitudinal beam design in automobile manufacturing, in particular to a square tapered aluminum alloy automobile front longitudinal beam based on embedded carbon fiber. Background technique [0002] The front side beam is an important part of the car crash safety design. During a frontal collision, the energy absorbed by the front longitudinal beam accounts for 50% to 70% of the total energy, and in an offset collision, it accounts for 30% to 50% of the total energy. The front side beam absorbs the most collision energy among all body parts, and its energy absorption characteristics and deformation mode determine the acceleration response and force transmission path during the collision process. Therefore, major automobile companies regard the optimal design of the front side beam as the body An important part of safety and lightweight design. The traditional car front longitudinal beam design us...
