Case study using seismic waves from the Great East Japan Earthquake!!
**Case Overview** ■Product Name: Simcenter Fema with Nastran ■Industry: Construction There are many structural forms for containers that store liquids and their supports. During an earthquake, the sloshing of the liquid surface inside the tank generates dynamic liquid pressure that acts on the container's side walls and bottom plate, leading to tank damage and rocking vibrations that can cause parts of the bottom plate to lift, resulting in tank damage. This case study utilized the virtual fluid boundary and phantom elements of Simcenter Nastran to perform transient response analysis on three types of tanks, as shown in the right diagram, using the seismic waves from the 2011 Great East Japan Earthquake (M9). Below, we present the sloshing behavior and dynamic liquid pressure distribution during the earthquake. * Downloaded from K-NET For more detailed information, please refer to the catalog or contact us directly.

We conducted a modal complex eigenvalue analysis at the specified rotation speeds to investigate the whirling modes due to rotation, changes in damping, and critical speeds.
**Case Overview** ■Product Name: Simcenter Nastran ■Analysis: Modal Analysis of Natural Frequencies ■Industry: Other The vibration characteristics of rotating bodies exhibit whirl motion due to centrifugal force, tilt vibrations, and gyroscopic effects as the axis rotates, resulting in changes in eigenvalues. When the direction of rotation and whirl motion align, it is referred to as forward whirl; when they are opposite, it is called backward whirl. When the rotational speed matches the eigenvalue of the axis, the amplitude of the whirl increases, leading to instability in the rotating system and potential damage to components. The speed at this point is referred to as the critical speed. In this analysis, modal complex eigenvalue analysis was conducted for specified rotational speeds to investigate the whirl modes induced by rotation, changes in damping, and critical speeds. □ For other functions and details, please refer to the catalog.

Reduce the computational load of large-scale models!! It can also be utilized for information security!!
**Case Overview** ■Product Name: Simcenter Femap with Nastran ■Industry: Mechanical Components The super-element feature of Simcenter Nastran reduces computational load by dividing large models for analysis or by simplifying parts of the model (external super-elements), thus making the analysis model smaller and shortening computation time when changes are made to other parts. In this case, we validated the analysis accuracy and evaluated the reduction in computation time by simplifying the unchanged boss section as an external super-element and analyzing it in conjunction with the mesh model of the blade section during the eigenvalue design of the fan blades. This method saves computation time, especially in design phases where performance evaluations and repeated calculations at the component level are common, and the more unchanged parts there are, the more significant the benefits. Additionally, by converting in-house component models into super-elements and providing them to other companies, the shapes can be treated as black boxes, thus enhancing information security. □ For other features and details, please refer to the catalog.
