摘要
针对汽车外覆盖件钢板材料的接触变形问题,建立了钢板抗凹性力学模型,并采用有限元方法对轿车发动机罩盖、顶盖与后备箱盖外板的静态抗凹性进行了数值模拟分析。研究结果表明,0.65 mm厚度180BH材料的车身覆盖件,其后备箱外板抗凹性相对其它区域较弱,最大变形量为5.301 mm,变形量满足车身抗凹性测试标准的要求,车身具有较好的抗凹性。研究结果为汽车外覆盖件的设计和评价提供了理论指导和数据依据。
Aiming at the problem of contact deformation of automobile outer panel steel plate, a mechanical model of steel plate dent resistance is established. The static dent resistance of engine cover, roof cover and trunk cover outer plate of automobile is numerically simulated and analyzed by finite element method. The results show that in body panels of 180 BH material with 0.65 mm thickness, the dent resistance of the trunk outer panel is weaker than that of other areas. The maximum deformation is 5.301 mm. The deformation meets the requirements of the anti-concave test standard of the body, and the body has good anti-concave property. The research results provide theoretical guidance and data basis for the design and evaluation of automobile outer panels.
