On Validation of Automatic Assembly of Structural Component Analysis Models to Build Large-Scale Structural Analysis Model

Key Points

• The research aims to develop a method for automatically setting multibody constraint conditions in large-scale structural analysis models using finite element methods.
• Developed mathematical approaches for analyzing multibody constraint conditions.
• Implemented a technique to eliminate degrees of freedom for multibody constraints.
• Utilized conjugate gradient method for solving global stiffness matrix equations without increased computational burden.
• Tested the method using small- to medium-scale analysis models.
• Confirmed that displacement continuity is maintained at contact surfaces with set multibody constraints.
• Validated that the computational load of the conjugate gradient method does not increase with the imposed constraints.
