When a structure such as a machine or a machine that combines mechanical elements receives an external force, numerical calculation is performed on the stiffness, stress distribution, and deformation amount of the structure, and the approximate value is obtained. 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, there has been commercialized a general-purpose structural analysis software capable of easily performing structural analysis by a personal computer due to improvement of computer performance. Most of these software can use shape data created with 3D CAD

Strength Interpretation

1) Example: Analysis of seat belt anchor strength.
2) Purpose: Analysis to confirm the strength and rigidity of seat belt assembly assembly (SEAT BELT ASSEMBLY ANCHORAGE) installed to reduce the damage to the wearer by restricting the movement of the passenger in case of sudden deceleration of vehicle collision.

Collision Analysis

1) Example: CARGO SECURING Strength Analysis
2) Purpose: Analysis to check the seat strength against LUGGAGE shock to prevent LUGGAGE (cargo) from entering the passenger space and causing injury to the passenger in frontal collision in FIELD

Testing (design verification)
