摘要
基于某款汽车仪表板的CATIA三维模型,应用Hypermesh软件进行建模和前处理,采用ALTAIR公司的SNRD模块在大鹅卵石路面激励下对仪表板进行摩擦异响分析,应用Optistruct求解器计算,在Hyperview中进行后处理,判断仪表板是否会发生摩擦异响,并找出对潜在异响问题贡献量最大的模态,为试验和仿真优化分析提供参考。
Based on the CATIA 3D model of a car's instrument panel,Hypermesh software is used for modeling and pre-processing.The SNRD module of ALTAIR is used to analyze the frictional noise of the instrument panel under the excitation of large cobblestone pavement,and the Optistruct solver is used to calculate.Post-processing in Hyperview,to determine whether the instrument panel will have abnormal friction,and find the mode that contributes the most to the potential abnormal noise problem,and provide reference for the experimental and simulation optimization analysis.
