Abstract

Safety, environmental protection and intelligence are targets and directions of automobile development, and automobile lightening is a significant way for energy conservation and emission reduction. Cementing has multiple advantages and is more and more widely used in new material lightened automobiles. The invention relates to an automobile body cementing structure health monitoring system which comprises an automobile body, a cementing structure, a data acquisition unit, a data storage and processing unit, a remote data center, a driver, an automobile maintenance center, a cementing layer, a connected material, a conductive filler and a lead. On-line load monitoring, damage positioning, damage analysis and residual structure service life prediction on an automobile body cementing structure can be achieved, the safety reliability of the cementing structure and the automobile body is improved, the maintenance cost is lowered, the service life is prolonged, and in addition service information acquisition and optimal design of lightened automobile structures can be facilitated.

Description

technical field [0001] The invention relates to the real-time acquisition and evaluation of the damage of the glued structure in the lightweight automobile body, in particular to an automobile body glued structure health monitoring system, which belongs to the field of vehicle safety and structural health monitoring. Background technique [0002] Safety, environmental protection and intelligence are the goals and directions of automobile development, and lightweight automobiles are an important way to achieve energy conservation and emission reduction. The body weight accounts for about 30 to 50% of the weight of its passenger car, and the lightweight of the body is very important for the lightweight of the whole vehicle. The mixed use of fiber-reinforced resin matrix composites, high-strength steels, aluminum alloys, magnesium alloys, and other lightweight materials is the trend of vehicle lightweighting. Adhesive bonding is a continuous connection method, which has the ad...
