Abstract: Methods and systems for analyzing stamped parts having a final shape for a vehicle are provided. A method includes receiving data for the stamped part; producing a computer simulation based on the data; determining a wrinkling index (WI) for the stamped part in response to the processor producing the computer simulation; determining whether an element under analysis is located at a trimmed edge of the stamped part; when the element under analysis is located at a trimmed edge of the stamped part, determining a stretching index (SI) for a trimmed edge portion, or when the element under analysis is not located at a trimmed edge of the stamped part, determining a SI for a plane stress portion in response to the processor producing the computer simulation; comparing the SI to a SI threshold and/or comparing the SI to the WI; and generating, using the processor, a uniform failure index (UFI).

Abstract: A system performs a method of manufacturing a vehicle. The system includes a camera, a transport device, and a processor. The camera obtains an image of a part that is to be assembled to the vehicle. The transport device orients the part with respect to a surface and drops the part onto the surface. The processor creates a first model representing the part and a second model representing the surface from the image, places the first model at a selected drop orientation and a selected drop height with respect to the second model, simulates a drop of the first model onto the second model, and determines a change in a dimension of the first model resulting from the simulated drop. The part is dropped onto the surface at the selected drop orientation and the selected drop height when the change in the dimension of the first model meets a criterion.
