Designers and engineers who are moving into the area of dynamic analysis who need to use FEMAP and Simcenter Nastran to perform those analyses to predict dynamic structural behavior under a wide variety of conditions.

Prerequisites: FEMAP 101 or similar work-related experience with FEMAP and Simcenter NASTRAN but no other background knowledge is required.

• Brief overview of theoretical solutions to simple dynamics problems
• Classifications of dynamics environments
• Dynamic excitation
• Practical modeling considerations
• Commonly used elements and how these should be used in dynamics analysis
• Tips and hints on model versification such as weight and Groundcheck
• Eigenvalue (Modal) analysis focusing on why and when to use modal analysis
• Important facts and results regarding mode shapes and natural frequencies
• Rigid body modes with an emphasis on issues of ridged body modes causes by errors in modeling
• Direct and modal frequency response and when and how to use.
• Frequency response analysis – with practical hint and tips
• Dynamic data recovery
• Viscous and structural damping
• Direct and modal transient reasons analysis
• Restarts of dynamics analysis
• Defining transient excitation
• Residual vector methods (getting better results even with few modes)
• Enforced motion (base input accelerations, displacements or velocities) for earthquake or swept sine shaker test simulations
• Random vibration and powerspectral density (PSD’s) input
