Abstract：

In order to solve the problem of lacking mechanical performance parameters for as-quenched aluminum alloy sheet in the digital design and production of aircraft sheet metal parts and provide the data support for process design and simulation of aircraft sheet metal parts, the material performance parameters were obtained by the mechanical performance test of as-quenched aluminum alloy sheet, and the parameters were saved in Access database. Then, the connection between the Access material database and the material parameters selection module in CATIA was established by ADO database access technology of Visual C++ to realize the automatic retrieval of the mechanical performance parameters for as-quenched aluminum alloy sheets by CATIA. The establishment of the database provides material data for the automatic compensation system of aircraft sheet metal rubber bladder forming die based on the secondary development of CATIA CAA, so that the system accurately simulates the springback compensation, simplifies the digital design and trimming process of die, and plays a promoting role in improving the manufacturing accuracy of aircraft sheet metal parts and saving cost.
