Abstract

The invention discloses a method for designing a finite element model of a colloidal finite element model of a collision honeycomb barrier, which comprises using a hexagonal shell element in cross section and cutting gaps between the six faces of the hexagonal shell element, and then Bend six faces inward at ninety degrees to form the flange faces. Then generate six-sided cubic units on the shell elements of each flange surface by parallel stretching method. One surface of these solid elements is connected with the shell elements on the flange surface through the same node, and the cube parallel to this surface The nodes on the other surface are connected to the front cover of the barrier model through a mathematical coupling algorithm. Through this special adhesive model, the energy-absorbing honeycomb barrier is bonded to the cover plate and the middle partition to form a three-piece whole barrier, and the overall honeycomb barrier module is installed on the fixed installation plate Above, the whole barrier is fixed on the collision rigid trolley or the rigid wall through the mounting plate.

Description

Technical field [0001] The present invention relates to the field of imitation modeling technology using a finite element algorithm, and more particularly to a finite element model design method for colliding honeycomb wall barrier adhesive. Background technique [0002] At the global automotive industry, with the continuous improvement of automotive safety performance, automotive enterprises for the safety requirements for development models and different national regulations, in order to save real-vehicle collision during model development, it is necessary to use a large number of finite yuan. Calculate the simulation of virtual collision simulation. During frontal collision, side collision, rear-end collision virtual simulation, according to different regulatory requirements, the boundary condition of this virtual simulation is completely consistent with the entire calendar collision setting in the actual collision laboratory. [0003] In order to make the CAE simulation calcu...
