Abstract

It is known that vehicle structural thickness change will lead to vehicle modal characteristics change .In this paper, the thickness of floor, sidewalls and vehicle top are chosen as the variables so as to calculate the relationship amongst thickness change and frequencies (Vertical bending- f1, Torsion- f2, Rhombus- f3),vertical nodes and the ratio of Vertical bending and Torsion respectively. The results show that structure size have a significant impact on the vehicle body natural frequency; In terms of the overall degree of influence, the vehicle top and vehicle top corrugated board have greater influence on f1, f2, f3 than the other size’s; For a given vehicle, in the premise of no significant increase in vehicle body weight, we can increase the natural frequencies f1, f2, f3 by adjusting the dimensions of the material. Also we can change the vehicle body vertical bending nodes by adjusting the component dimensions, and increase the thickness of the vehicle top to improve the ratio of vehicle body vertical bending and torsion, and reduce the ratio of vehicle body vertical bending and torsion by increase the floor, sidewall thickness. But how the floor thickness affect the ratio of vertical bending and torsion depends on thickness which has been designed.
