汽车全塑前端模块支架刚度的研究

传统的汽车前端是非模块化设计的,一般由10～ 20个钢制冲压零件焊接成一个框架,然后将散热器、车灯和锁等零/部件分别安装在钢制框架上.此钢制框架属于车身的一部分,重量重、焊接组装复杂,成本高.因此,提出采用一种玻纤增强的复合材料整体注塑成型的全塑料框架,替代传统的钢制框架,集成汽车前端各种零件,形成一个大的模块组件,然后整体装在车身上.与传统的汽车前端相比,不但安装与拆卸方便,且使车身前端重量减轻,成本降低,是未来汽车行业发展的趋势所在.重点对其刚度进行了详细的研究.

The stiffness study of automobile plastic front-end module frame

The front-end of traditional automobile is designed through non-modular,and it is generally a welded frame which is consisted of 10~20 metal stamping and punching parts.Radiators,lights,locks and other parts are then installed in this steel frame which is belong to the part of the automobile body.This frame is not only heavy but also costly.And its weld and assembly is complex.The plastic frame injected with reinforced composite materials of a glass fiber is used instead of traditional steel frame.This plastic frame integrated with front-end various automotive parts is a large module component,packed into the automobile body as a whole.Compared with the traditional front-end,this frame is both easier to be installed and removed,and lower about the front-end body weight and cost.Then it is the future development trend of the automobile industry.Makes detailed study about its stiffness.
