摘　　要：为了快速评价产品模块组合的多种配置方案,并且能够通过修改子模块结构及其配置方式,达到满足产品整机动态特性的客户要求,提出了一种基于试验/有限元模态分析模型的产品整机模态综合方法。以小型农业作业机为研究对象,根据小农机的结构特征与工作模式,对其进行了功能模块划分;并根据产品模块的模态试验或有限元模态分析结果,完成了小型农业作业机产品整机动态性能的快速模态综合求解,并通过整机试验模态综合方法进行了求解结果的有效性验证。研究结果证明,上述方法能够根据具体产品模块配置组合,快速有效地进行配置样机的模态求解,大大提高了产品配置设计效率。In order to cater for the dynamic characteristics forecasting demand of product in configuration design process,a product modal synthesis method based on the experiment/finite element modal analysis models of product modules was proposed.With small agriculture machinery design as example,according to the product structural characteristics and working modes,the function module partition was carried out,and the whole modal of configuration prototype was acquired through modal synthesis with product modular＇s modal test and finite element modal analysis.The results show that the above-mentioned methods can forecast the whole mode of the prototype,greatly improving the product configuration design efficiency.
