摘要: 通过实验测试与回归分析相结合的方法,研究了半圆形拉深筋的圆角半径和金属流动方向对拉深筋阻力的影响。通过专门设计的实验装置,分别测取了以圆角半径和金属流动方向为变量的拉深筋阻力数据,分析得出圆角半径对拉深筋阻力的影响呈近似线性关系,金属流动方向对拉深筋阻力的影响呈近似的抛物线关系。综合两个参数的影响规律,基于回归分析方法建立了拉深筋阻力的近似解析模型。最后,通过回归系数的T检验得出,金属流动方向对拉深筋阻力的影响要比圆角半径显著,并且金属流动方向与圆角半径的耦合效应较小。

Abstract: The effects of drawbead corner radius and metal flow direction on drawbead restraining force are studied by experiment testing and regression analysis. Experimental data are acquired respectively by a specially designed experiment device, in which the variable is the corner radius or metal flow direction. An approximate linear relationship exists between the corner radius and drawbead restraining force, while the relationship between the metal flow direction and drawbead restraining force is nearly parabolic. An approximate analytical model of drawbead restraining force is established based on the influence law and regression analysis. Finally, by T test of regression coefficient, it is concluded that the metal flow direction has stronger impact on drawbead restraining force than that of the drawbead corner radius. Besides, the coupling effect of metal flow direction and corner radius is insignificant.

Key words: vehicle engineering, drawbead, corner radius, metal flow direction, drawbead restraining force, regression analysis
