Pre-verification
- At each stage in the development process, Seoyon E-Hwa is carrying out pre-verification activity such as analysis, assembly verification, assessment of harmful factors etc. on parts by means of ‘CAE’ and ‘DPA’ technology. After part development, we aim to minimize potential failure cost through ‘BSR assessment’, ‘ES testing, ‘side impact testing’.
Applied field and effect
-
- 1. CAE(Computer Aided Engineering)
- 1) Structure and dynamic interpretation
- - Analysis of flexural/torsional/modal characteristics of door trims, bumpers, pillars, and seats - Analysis of static stiffness and non-linear strength of various parts to prevent vibration noise etc.- Optimization of head lining & pillar trim structure for FMH satisfaction
-
- 2) Mold Flow Analysis
- - Analysis of optimal molding conditions through gate position and clamp force examination
- Analysis of cooling channel optimization for optimum cooling temperature and minimization of cycle time
- Improvement of product surface problems (BURR, WELDLINE, SINK, FLOW, SILVER etc.) -
- 2. DPA(Digital Pre-Assembly)
- - Verification of assembly : Planning data quality improvement through verification of data and tool interference/part workability
- Assessment of harmful factors: Prevention of musculoskeletal disorder through workability assessment when assembling parts -
- 3. Test & Evaluation
- - BSR assessment : Structure optimization for minimization of squeak & rattle noise
- ES test : Interpretation of vibration for avoiding resonance of interior part and suspension seat
- Side Impact test : Door trim and IP & seat structure optimization for securing impact safety -
