PC for the operation of the collision analysis support tool "HYCRASH" considering work hardening.

Automatic generation of initial conditions for Ansys LS-DYNA!! Quickly respond to vehicle design changes with "HYCRASH" operational PC.

◆Automatic Generation of Initial Conditions for Ansys LS-DYNA: Rapid Response to Vehicle Design Changes In collision analysis, we aim for further accuracy improvements by considering the initial conditions of press-formed materials, such as sheet thickness and plastic strain. Since FEM meshes are created according to the respective purposes for press forming analysis and collision analysis, it is common to map the results of press forming simulations to the collision model due to differences in modeling of the R parts and mesh sizes. However, this method requires time for changing the analysis model or re-simulating when design changes occur, making rapid response difficult. HYCRASH solves this issue by automatically generating initial conditions for Ansys LS-DYNA using the collision model itself! ◆Automatic Generation of Collision Model Data: Improving Analysis Accuracy and Efficiency The only required input data is the collision analysis model. By simply specifying the part number of the press-formed material, HYCRASH conducts forming analysis for all those parts and fully automatically generates new collision model data. Since the collision model data includes initial conditions such as sheet thickness and plastic strain from the forming analysis results, it enables highly accurate collision analysis.
