摘要

摘要: 针对车身覆盖件抗凹性优化问题，在现有工程中使用有限元数值模拟方法及相应工程经验基础上，开发基于可变工况的车身覆盖件抗凹性全流程优化方法。以某车型翼子板为例，采用Tcl/Tk语言编制脚本，快速建立了考虑材料非线性和接触非线性的仿真模型，经Abaqus软件计算得到抗凹性结果，再利用简化了的脚本定制优化参数，对工况变动的结构进行优化。结果表明，此套全流程优化方法解决变工况抗凹性问题快速，高效，准确。

Abstract: Aiming at the optimization for dent resistance of cover body, a whole process method is developed with FEM and the engineering experience to solve the dent resistance problem. The script for fast simulation model is developed considering the material nonlinearity and contact nonlinearity via Tcl/Tk language, the dent resistance is calculated with the Abaqus software. The structure for the variable conditions is optimized with the simplified script parameters. The results show that the present optimization method of whole process for solving the dent resistance for variable conditions is quick, efficient and accurate.
