摘要
介绍了车身设计中利用先进计算机模拟软件进行模拟分析的重要性。以某型号车门为研究对象,在相同加载情况下,分析了车门关闭和开启状态下的性能。探讨了车门在这两种状态下的能量平衡、门锁处Z向位移以及车门内板应力分布情况。进行模拟分析之后,发现车门变形较大,门板角落处存在应力集中,在铰链处应力集中比较严重。通过深入分析,提出了具体的改进措施,为新车型的开发研究提供了有力支持。
The significance of using computer simulation software to design new type automobile is presented in this paper. The performance of the open and close auto-door under the same load was analyzed. This paper discussed the energy distribution, Z directions displacement and stress distribution of the door. By simulation analysis we found that door deformation is obvious, stress concentration exist at corner; especially at door hinge. After detail analysis provided improve method to support the development of new type automobile.
