| Abstract: | Springing back of the plate after forming greatly affects its precision. So it sppears to be very important to have a precision forecast of the resilience in numerical value simulation. The advantages and shortcomings of several methods for calculating the plate resilience were analyzed and compared. Calculating the resilience by the static implicit method was found to be more suitable. Taking MARC as the platform, a system for calculating the plate resilience was established. The three dimensions' resilience after bending was calculated, and the reliability of the calculation was verified by the consistency of the calculated result and the experimental result. |
