Abstract: 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.
