Uncover Design Flaws with Forming Simulation
Dynaform is a complete die system, LS-DYNA based simulation solution for the automotive, electrical, stamping, and tool & die industries. It allows organizations to evaluate alternative and unconventional designs and materials while reducing costs, eliminating prototype tooling, and improve product performance.
By simulating the die system, during the design stage, Dynaform ensures the highest quality formed part and most efficient manufacturing process possible.
The BSE module is used for the unfolding of three-dimensional sheet metal parts and for estimating the blank size along with blank nesting the maximum material usage scrap, and piece price. BSE can be used to predict thinning, thickening, and to generate a forming limit diagram (FLD).
The FS module facilitates the rapid development and validation of the single-station, progressive and line die design. It uncovers hidden problem areas and enables the ability to optimize designs based on accurate forming results.
Dynaform’s D-Eval module is tailored to analyze CAD based tooling designs during the early stages of the product development cycle. It is equipped with the stamping purpose increment solver, which generates reliable formability results in a suitable timeframe.
The DSA module efficiently predicts many stamping concerns within the stamping production line. DSA consists of three unique capabilities; Die Structure Integrity (DSI), Scrap Shedding/Removal (SSR), and Sheet Metal Transferring/Handling (SMTH). The DSI simulates operational loads to analyze the design integrity of the die. It can generate FEA models of the die structure, define operational and stamping loads, evaluate the die structure strength, and durability by incorporating implicit solutions. The number one cause of stamping line shutdowns is the failure of scrap from exiting the workstation. This problem can be predicted and corrected in the trim die design stage which will help to avoid possible troubleshooting in the plant. The SHR streamline, models the generation for scrap, trim dies, chutes, and trim steel. The trimming operations and shedding simulations can be easily set up in the scrap shedding graphic interface. SMTH simulates the transfer of metal as it progresses through the manufacturing process, simulating the transfer of the work-piece to the initial die station, movement between stations, pick-up of the finished part, and the placement on the shipping rack. Part of the deformation generated in the simulation is used to predict the interference between the work-piece and the tools. The stress and strain results can be used to prevent damage during transport, loading, and unloading operations.
BSE-in-NX is a complete solution for accurately estimating blank size and blank nesting the maximum material utilization, minimum scrap, and piece costs—all within the familiar NX environment. The solution can quickly produce a blank outline for blank size estimation along with piece price and scrap calculation.
D-Eval-in-NX allows engineers to analyze the die design within the NX environment using an efficient, non-linear finite element program that is exclusively developed for simulation of sheet metal forming processes.
