Case study: Hull strength analysis using the finite element method.

Case study: Hull strength analysis using the finite element method.

A full hull model close to the actual structure was created, and strength analysis of the model was conducted.

**Case Summary** ■Product Name: Simcenter Femap with Nastran ■Analysis: Linear Static Analysis ■Industry: Railways and Shipping Finite element method strength calculations are widely used in hull design. The hull structure, composed of many components such as decks, side plating, double bottoms, bulkheads, and longitudinal and transverse strength frames, is complex, making it difficult to analyze just a part of it. This example created a full model close to the actual structure and conducted a strength analysis of the entire hull model. - The mesh generation feature of Simcenter Femap allows for the creation of complex hull FEM models. - Creation and management of loads such as static/dynamic water pressure and cargo conditions. - Improved computational efficiency through continuous analysis of multiple load cases. - The parallel processing capability of Simcenter Nastran enables analysis of large-scale models. □ For other features and details, please refer to the catalog.

[Example] Rotating Dynamics Eigenvalue Analysis

[Example] Rotating Dynamics Eigenvalue Analysis

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.

Case Study: Thermal Fluid Analysis of a Muffler

Case Study: Thermal Fluid Analysis of a Muffler

Introduction of recommended software examples for Simcenter Femap users starting thermal fluid analysis.

**Case Overview** ■Product Name: Femap Thermal, Femap Flow ■Analysis: Thermal Fluid Analysis ■Industry: Automotive Femap Thermal/Flow is software for thermal fluid analysis that operates as a Femap application. It can be used with the same operational feel as Femap. By combining Femap Thermal and Femap Flow for thermal fluid analysis, we calculated the flow of exhaust gases within the muffler and the temperature distribution of the muffler due to high-temperature exhaust. Using Femap Thermal and Femap Flow simultaneously allows for thermal fluid analysis. It can solve complex problems such as heat transfer at the fluid-structure interface, fluid flow, thermal conduction in structures, and consideration of radiation at the surface of structures. In this case, we conducted thermal fluid analysis focused on the muffler. We confirmed that we could obtain the temperature difference of exhaust gases at the inlet and outlet, the flow of exhaust gases within the muffler, and the temperature of the surface of the muffler structure, providing the parameters necessary for design. □ For other features and details, please refer to the catalog.

[Example] Vibration of liquid tanks and sloshing of the liquid surface during an earthquake.

[Example] Vibration of liquid tanks and sloshing of the liquid surface during an earthquake.

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.

[Example] External Super Element

[Example] External Super Element

Reduction of analysis costs, enhancement of information security!!!

【Case Overview】 ■Product Name: Simcenter Femap with Nastran There has been an image that Super Elements (SE) are only applicable in the aerospace and automotive fields and can only be used by a few dedicated analysts. There has been no pre-post that fully supports SE analysis, and the data creation process has been complicated, which has hindered its widespread adoption until now. Simcenter Femap supports external Super Elements from Simcenter Nastran, making SE analysis accessible to everyone.

[Example] Efficiency improvement of repetitive calculations using the super element function.

[Example] Efficiency improvement of repetitive calculations using the super element function.

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.
