Study on the Structure Parameters Simulation and Optimization for Stamping Quality of Plate Heat Exchanger

摘要

CAD/CAE model of plate structure is designed for plate heat exchanger provided by the manufacturer. Stamping process of the plate is simulated using Dynaform which is the special software of numerical simulation for sheet metal. The quality of plate stamping is analyzed by thinning rate, forming limit diagram (FLD) and other indicators, and compared with practical problems. At the same time, twelve levels experiments programs including ripple inclination, ripple normal pitch and ripple height are established according to uniform design principles based the parameters of ripple structure provided by manufacturer, and twelve chevron ripple plate models is established and their forming quality is analyzed with Dynaform Software. Influence and laws of plates three structural parameters, plates' section parameters, BHF for stamping quality are studied and summarized, and the optimal choice of the plates is fond out to provide a theoretical basis for the actual production.
