When a structure such as a machine (or a machine that combines mechanical components) receives an external force, numerical calculations are performed to measure the stiffness, stress distribution, and deformation amount of the structure. Structural analysis is roughly classified into linear analysis in the elastic region and nonlinear analysis in the plastic region.
As a numerical calculation method, a finite element method (FEM) is often used. In recent years, a general-purpose structural analysis software has been commercialized that is capable of easily performing structural analysis via personal computer. Most of this software can use shape data created by 3D CAD.
Strength analysis
1) Example: Analysis of seat belt anchor strength.
2) Purpose: To reduce the damage to the wearer by restricting the movement of the passenger when sudden deceleration of the vehicle collision accident, the strength of seat belt ass'y assembly (SEAT BELT ASSEMBLY ANCHORAGE) And interpretation to confirm rigidity.
Crash analysis
1) Example: CARGO SECURING STRENGTH ANALYSIS
2) Purpose: Analysis to check seat strength against LUGGAGE shock to prevent LUGGAGE (cargo) from entering the passenger space and causing injury to the passenger during frontal collision in FIELD.
