Abstract

The invention discloses a design method of a composite material automobile B column. A CFRP / high-strength steel composite structure is adopted, CFRP layering design, CFRP-high-strength steel connection design, CAE modeling and simulation analysis, performance verification and the like are conducted, and the common technical problems of structural design optimization, performance evaluation, connection evaluation and the like of the carbon fiber-thermal forming steel part can be solved. According to the design method of the composite material automobile B column, the strength and rigidity of the designed automobile B column of the high-strength steel and CFRP composite structure are improved by about 10% compared with those of an automobile B column of an original structure, rapid mold pressing integrated forming of carbon fibers and metal is achieved, and sufficient verification is provided for mass production of products.

Description

Technical field [0001] The invention relates to the field of automobile parts production, in particular to a design method of a composite material automobile B-pillar. Background technique [0002] With the development of the automobile industry, the number of automobiles has increased rapidly, and energy problems and environmental protection are facing severe forms. As an effective countermeasure, automobile lightweight is a research hotspot in the current automobile industry. Automobile lightweighting mainly reduces the weight by optimizing the design of the automobile structure and reducing the thickness; or replacing the original steel and other materials with new lightweight materials such as aluminum alloys and composite materials. [0003] Carbon fiber composite materials are among the current commonly used materials with better performance, with higher specific stiffness and specific modulus. Carbon fiber composite materials have excellent properties such as light weight,...
