[Example] Hull strength analysis using the finite element method

[Example] 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 Overview** ■Product Name: NX 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 plates, 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 that closely resembles the actual structure and conducted a strength analysis of the entire hull model. - Creation of complex hull FEM models using Femap's mesh generation capabilities - Creation and management of loads such as static/dynamic water pressure and cargo conditions - Improved computational efficiency through continuous analysis of multiple load cases - Analysis of large-scale models made possible by NX Nastran's parallel processing capabilities □ For other features and details, please refer to the catalog.

[Example] Large-scale finite element analysis of train vehicle dynamics

[Example] Large-scale finite element analysis of train vehicle dynamics

An eigenvalue analysis of a 10-car train model was conducted using NX Nastran, and the natural frequencies up to 20 Hz were obtained.

**Case Overview** ■Product Name: NX Nastran ■Analysis: Modal Analysis ■Industry: Railways and Shipping Since railway vehicles operate in a coupled manner, it is necessary to analyze the motion characteristics of the entire train when considering vehicle dynamics. To accurately predict the vibrations generated in various parts of the moving vehicle, a vehicle simulation using a finite element model (FEM) that closely resembles the actual structure, rather than a uniform beam or equivalent plate structure, is required. On the other hand, such analyses heavily depend on the computational environment, model creation, and result visualization capabilities, necessitating parallel computing solutions and efficient pre/post-processing software. This example involves creating the vehicle body using Femap and conducting a modal analysis of a 10-car train model with NX Nastran to determine the natural frequencies up to 20 Hz. Additionally, the application of FEMAP and GLView for post-processing large-scale finite element analyses will be introduced.

Case Study: Thermal Fluid Analysis of a Muffler

Case Study: Thermal Fluid Analysis of a Muffler

This is an introduction to the recommended software Femap Thermal/Flow for customers who are starting thermal fluid analysis with Femap.

**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. Through the combination of 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. By using Femap Thermal and Femap Flow simultaneously, thermal fluid analysis can be conducted. 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 necessary parameters for design by determining 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. □ For other functions and details, please refer to the catalog.

[Example] Thermal conduction analysis using thermal coupling functionality

[Example] Thermal conduction analysis using thermal coupling functionality

We analyzed the temperature distribution of heat conduction due to heat generation from the chip in a structure composed of a chip, substrate, edge guide, and case.

【Case Overview】 ■Product Name: Femap Thermal ■Analysis: Thermal Analysis ■Industry: Mechanical Components Modeling thermal connections between components can be challenging due to thermal resistance from contact and heat conduction at adhesive joints. By using the thermal coupling feature, it is possible to define conductive conductance, thermal conductivity, or thermal resistance values between distant meshes that do not share nodes, allowing for thermal coupling in calculations between these distant meshes. This is an excellent feature that automatically considers the positional relationships of elements and allocates the degree of thermal coupling for each element. In this analysis case, we will analyze the temperature distribution due to heat generation from a chip within a structure consisting of four types of components: chip, substrate, edge guide, and case. The adhesive between the chip and substrate, as well as the edge guide that connects the substrate and case, were modeled using thermal coupling. □ For other functions and details, please refer to the catalog.

[Example] Linear static analysis considering initial bolt load

[Example] Linear static analysis considering initial bolt load

Linear static analysis using beam elements and bar elements for bolt connection parts!!!

**Case Summary** ■Product Name: NX Nastran ■Industry: Mechanical Components NX Nastran allows for various analyses considering pre-tensioned bolts (linear static analysis, nonlinear static analysis SOL601, linear buckling analysis, etc.). Using the Femap interface, modeling of bolt connections with beam elements, bar elements, and solid elements, as well as the setting of bolt loads, can be done easily. This case modeled the bolts using bar elements and solid elements and compared the results from both methods. Two fittings with a surface static friction coefficient of 0.15 were fastened with M10 bolts. An axial force of 150 kgf was applied, with one side fixed, and a linear static analysis was performed (Figure 1). The comparison of results from the bar elements and solid elements showed that the maximum and minimum Mises stress values and the maximum and minimum displacement values for the two fittings were the same for both methods. ● For more features and details, please download the catalog.
