[0038] Optimization steps for car dashboard beams:

[0039] 1) Select the main material of the beam;

[0040] 2) Determine the main mounting bracket;

[0041] 3) Adjust the overall stiffness of the instrument panel beam;

[0042] 4) Increase the first-order frequency of the beam;

[0043] 5) Use ABAQUS and NASTRAN tools for analysis: suspend the instrument panel beam flexibly, use the exciter as the excitation source, select 30 points on the instrument panel beam for vibration pickup, and test the direction perpendicular to the normal direction of each measuring point of the car door;

[0044] 6) Carry out grid division: the basic data beam body model is divided into grids under constraint conditions;

[0045] 7) In the stage of grid division, use the pre-processing software to process the grid: focus on dividing the solder joints, the joints of the sub-supports, the joints of the rounded corners and reinforcing ribs, and modify the deformed grid holes; handled evenly and ...

Abstract

The invention provides a method for optimizing an automobile instrument cross beam. The method aims at solving the problems that when novel instrument cross beam design is developed, the development cost and the physical experiment cost are high, and the labor cost is increased due to long development time. According to the technical scheme, by means of a quantitative design mode, design errors are reduced, and structural design is optimized. The method has the advantages that on the basis of guaranteeing high inherent frequency and high structural strength, the weight of the product structure is reduced as much as possible, the production cost is reduced, and function design is achieved.
