Abstract

The invention discloses a method for detecting the firmness of a carbon fiber accessory for an automobile. The method comprises the following steps: inputting layer laying information of the carbon fiber accessory into a calculation file; inputting the mechanical performance of the carbon fiber accessory; discretizing the carbon fiber accessory, and establishing a finite element analysis model; selecting a weak point from the carbon fiber accessory, and generating a virtual pressure head to carry out stress analysis on the weak point; and outputting a stress analysis result. According to the method, the instability area of the carbon fiber accessory can be conveniently found out through virtual detection; and whether the firmness requirement is met or not can be evaluated in the design stage of the carbon fiber accessory, design adjustment can be synchronously carried out when insufficient firmness is found, and the product design cycle is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of automobile bodies, in particular to a method for detecting the robustness of carbon fiber accessories for automobiles. Background technique [0002] With the development of new energy vehicle technology, more and more new energy vehicles have been chosen by people. In order to reduce the weight of the new energy vehicle and increase the cruising range, the carbon fiber material hood will be used as one of the technical solutions for weight reduction. Under normal circumstances, users will press the surface of the carbon fiber material hood with their palms to check whether the hood is firm. If there is a crackling sound during the pressing process, it will give the user the impression that the body is not strong enough, and affect the user's desire to buy. . In order to ensure the robustness of the carbon fiber material hood, experimental methods are usually used to detect it. However, the existing det...
