[Example] Vibration of liquid tanks and sloshing of the liquid surface during an earthquake.
Simcenter Femap with Nastran
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.
