Integrated Forming Simulation System for
Virtual Tool Shop
Functions and Features
Crack/Wrinkle Evaluation (e.g. Dash Upper)
The accuracy of JSTAMP/NV is shown by comparing the results between virtual
simulation and actual try.(Courtesy of G-TEKT CORPORATION)
JSTAMP/NV accurately predicts the locations and sizes of two cracks. (JSTAMP/NV shows thinning distribution.)
JSTAMP/NV accurately predicts the wrinkles.(See the locations and shapes of the wrinkles)
Crack Evaluation (e.g. Hood Inner)
By the comparison between JSTAMP/NV result and the actual try product, it can be shown that JSTAMP/NV predicts accurately the location of crack of the Hood Inner panel. Around hinge region shows over 30% of thinning in the simulation. Actually, the crack is recognized at the same region of the actual try product. This crack can be removed through the convinient JSTAMP/NV features. Specially using in the re-analysis feature, the die face geometry or product geometry can be substituted to the new ones partially or totally.
Initial Blank Line Evaluation
Trim Line Evaluation
Kinematic Hardening Material Model: Yoshida-Uemori Model
CAD surfaces compensated can be generated from JSTAMP/NV springback compensation.
Multi-Stage Process Management (Intuitive Analysis Condition Setting)
Most of design changes can be controlled easilly through the Re-Analysis Function in JSTAMP/NV. Design change anternatives are generally a blank material, initial blank position and size, and geometries of dieface or product. JSTAMP/NV Re-Analysis function gives a template that defines design changes above mentioned. These changes can be checked conveniently using another powerful function, Process Comparison, in JSTAMP/NV.
The material database of JSTAMP/NV provides more than 100 material types including high strength steel sheet and aluminum sheet as the standard database. Also, the test results by user can be added to the JSTAMP/NV material database easily. In case of unsufficient material data, the simulation could start immediately using JSTAMP/NV material database. JSTAMP/NV material database is being renewed progressively.
Hierarchical Management of Material Database
Not only master material data but also the user material data can be managed by the user.
