Computer Aided Design (CAD)
A parametric 3D-CAD system provides :
• 3D-designing
• automated generation of drawings
• basis finite element analysis (FEA)
Finite-Element-Analysis (FEM)
The finite element analysis is used for verification and improvement of structures:
• stess analysis
• deformation analysis
• contact analyse fo sealing areas (especially for metal seated systems)
• gap analysis (e.g. for sealing grooves)
Stress/Strain Measurement
Especially for critical areas te stress/strain measurement by strain gauges ist used:
• experimental dedection of strains and stresses
• verification of the results of finite element analysis
