Empirical Models between User Requirements and Product Structural Variables: A Hydraulic Forging Press Case Study

摘要

To effectively determine the key parameters of a model for complex mechanical products like hydraulic forging press (HFP), design cases were analyzed, user requirements (URs) quantified, and important mechanical structural variables (SVs) addressed to identify the underlying relationships between URs and SVs. By including experts' experiences, empirical models were mathematically built and verified basing on the linear regression theory, and then applied to estimate practical variable values. The programmatic framework presented for the preliminary design of a product was implemented and successfully demonstrated on the preliminary design of an HFP company.
