Simulation Technology Advantages
Sigma robust simulation for big parts, aluminum parts and high strength steel parts, all influential factors such as blank position (vary ±3mm), the anisotropic coefficient fluctuations (vary ±20％ )，blank thickness (vary -5％), material yield strength (vary ±10％ ), material tensile strength (vary ±10 ％), binder force (vary ±10％ ) and the friction coefficient fluctuations the friction (vary ±10％ ) are fully considered to remove tryout difficulty at post tryout stage.
Based on the theoretical understanding of springback phenomenon and the summary of experience, a robust standard of CAE springback compensation strategy is developed to ensure the maximum consistency between predicted theoretical springback and the actual springback conditions
