![[Case Study] Buckling Analysis of Thin-Walled Frame Structures](https://image.www.ipros.com/public/product/image/53f/2000006042/IPROS7955015379070885300.jpg?w=280&h=280)
We performed advanced nonlinear analysis using NX Nastran for the elastic-plastic buckling problem of frame structures.
【Case Summary】 ■Product Name: NX Nastran ■Analysis: Nonlinear Static Analysis ■Industry: Mechanical Components Buckling is a deformation that exhibits very strong nonlinear characteristics. When buckling occurs, the strength and stiffness of the structure decrease sharply, leading to instability. Thin-walled frame structures, like the one shown on the right, have many failure modes, and buckling can cause extremely large deflections in the frame. Since part of the model may return from an elastic state to a plastic state and vice versa, the analysis becomes quite complex. This analysis example presents the results of advanced nonlinear analysis using NX Nastran for the elasto-plastic buckling problem of frame structures. □ For other features and details, please refer to the catalog.

【Case Overview】 ■Product Name: NX Nastran ■Analysis: Nonlinear Static Analysis ■Industry: Other Buckling is a deformation that exhibits very strong nonlinear characteristics. When buckling occurs, the strength and stiffness of the structure decrease sharply, leading to instability. Shell structures, like the one shown in the right diagram, are thin-walled and therefore have many local failure modes in addition to overall compressive buckling. During the buckling process, there is also contact within the shell itself. This analysis example presents the advanced nonlinear analysis results of NX Nastran for the nonlinear buckling problem of shell structures. □For other features and details, please refer to the catalog.

Using the virtual fluid capabilities of NX Nastran, we investigated the changes in the natural frequency of a cantilever in a vacuum, in the atmosphere, and in water.
【Case Overview】 ■Product Name: NX Nastran ■Analysis: Linear Static Analysis, Modal Analysis, Frequency Response Analysis ■Industry: Other A cantilever is a sensor that detects the interaction force between the probe and the sample in atomic force microscopy by measuring changes in displacement or resonance frequency. It is applied in fields such as precision machining and measurement of nanostructures. Since the detection sensitivity is determined by the mechanical properties of the cantilever, it is very important to determine those properties; however, the spring constant and resonance frequency of the cantilever can vary significantly depending on the vibrating environment. In this analysis example, we used the virtual fluid function of NX Nastran to investigate the changes in the natural frequency of the cantilever in a vacuum, in the atmosphere, and in water. □ For other functions and details, please refer to the catalog.

This analysis example introduces a drawing process for a corner box-shaped container.
**Case Overview** ■Product Name: NX Nastran ■Analysis: Nonlinear Static Analysis ■Industry: Mechanical Components Plastic processing primarily involves forming processes that include contact between tools and workpieces. Among these, the method of forming bottomed containers from metal sheets using a punch and die is called deep drawing. Various factors such as the structure and material of the mold, the shape of the blank, and friction conditions influence the process, resulting in changes in the stress distribution in different parts of the blank during forming, leading to issues like cracking and wrinkling. This analysis example introduces a deep drawing case of a rectangular box-shaped container. The initial shape of the blank is 200x200 with a thickness of 0.82mm. The die is a rigid flat plate with a square hole measuring 102.5x102.5 with rounded corners of 10mm radius. The punch is a rigid body with a size of 100x100 and has steps, and similarly, the wrinkle suppressor is also a rigid flat plate. □ For other functions and details, please refer to the catalog.

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.

Reduce the computational load of large-scale models!! It can also be utilized for information security!!
**Case Summary** ■Product Name: NX Nastran ■Industry: Mechanical Components The super-element feature of NX Nastran reduces computational load by dividing large models for analysis or by reducing parts of the model (external super-elements) to create a smaller analysis model, thereby shortening computation time when changes are made to other parts. In this case, when designing the natural frequency of a fan blade, the non-changing boss section was reduced as an external super-element and analyzed in conjunction with the mesh model of the blade section to verify analysis accuracy and evaluate computation time reduction. This method saves computation time in cases where there are many repetitive calculations, such as performance evaluations during the design phase or countermeasure considerations at the component level, 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, which can also be utilized for information security. □ For other features and details, please refer to the catalog.

Analysis of golf club heads using optimization!!!
It is ideal for the characteristics of the golf club head to match the characteristics of the golfer, allowing for maximum performance of its capabilities.

We created a process using ModelCenter, an optimization support tool, to analyze the impact of face structure and shaft stiffness on initial speed. This enabled us to examine the influence of each parameter and seek the optimal golf club characteristics. For more detailed information, please refer to the catalog or contact us directly.

Nonlinear static analysis conducted on the behavior of diaphragm springs! Reproduction of the jumping phenomenon.
We would like to introduce our analysis titled "Behavior Analysis of Diaphragm Springs Using Nonlinear Static Analysis." When a load is applied to a disc spring, the shape of the spring is complex, resulting in not only bending but also twisting and buckling.
