摘要
研究采用HyperWorks软件对某车企提供的3d模型进行分析,并在车门上的6个位置分别施加600 N的刚性球作用,进而找出车门在受力作用下的薄弱位置。在3D模型优化方面,研究通过建立目标函数的方式来规范车门模型,并从起筋角度、高度和宽度等方面的角度对车门模型进行优化,最终输出优化后的车门3D模型。为验证该优化方案的有效性,研究对车门重构模型进行模态分析,发现经过优化后的车门目标位置模态频率得到显著提升,各受力位置的抗凹位移均维持在3mm以内,符合车企所提出的最大位移要求。
In this study,HyperWorks software was used to analyze the 3D model provided by an automobile company,and a rigid ball of 600N was applied to six positions on the door to find out the weak position of the door under the force.In terms of 3D model optimization,the car model is standardized by establishing an objective function,and the door model is optimized from the perspectives of stiffener length,height and width,and finally the optimized 3D model is output.In order to verify the effectiveness of the optimization scheme,the modal analysis of the vehicle reconstruction model was carried out,and it was found that the modal frequency of the optimized door target position was significantly improved,and the anti-concave displacement of each stress position was maintained within 3mm,which met the maximum displacement requirements of the automobile enterprise.
