CAE Business

Professional Engineering Solution Services

VPK supplies diverse and accurate solutions for research and design in various fields, including automobile, machinery, metal, electricity, and electronics. Based on FEM (implicit and explicit finite element methods) and BEM (Boundary Element Method), the Company analyzes various structures, acoustics, and collisions to evaluate strength, life span, safety, and acoustic performance. Advanced design techniques such as sensitivity analysis and topology optimization are applied to optimization tasks.
The Team operates a testing facility that can experimentally verify various material properties, boundary conditions, and analytical models that are entered into CAE. Moreover, the Team uses these practical CAE analyses to predict performance, improving the efficiency of design processes and reducing design costs.
