【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: 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.

【Case Overview】 ■Product Name: NX Nastran ■Analysis: Modal Analysis and Frequency Response Analysis ■Industry: Architecture Indoor acoustic characteristics are very complex, and the influence of standing waves on acoustic properties is significant. The acoustic analysis in NX Nastran is a fluid-structure interaction analysis that examines the vibrations within a container filled with fluid. In this analysis, the standing waves in a rectangular room were calculated, and the frequency characteristics of the acoustics driven by a point sound source were determined. *Note 1: Nastran includes elements for sound absorption and damping (acoustic absorbers/acoustic barriers), but this analysis does not take them into account. The walls of the room are considered to be perfect reflectors. □For other functions and details, please refer to the catalog.

**Case Summary** ■Product Name: NX Nastran ■Analysis: Frequency Response Analysis ■Industry: Electrical and Electronics Ultrasonic motors are actuators that generate ultrasonic vibrations in the stator through piezoelectric elements, driving the rotor via friction. They feature low-speed, high-torque operation without gears, fast response, high holding torque, quietness, and non-magnetic properties. Practical applications are being advanced in various fields such as optical devices, precision instruments, information equipment, medical devices, and transportation equipment. In this analysis, two bending vibrations with a 90° phase difference were excited in the stator of disk-type and ring-type traveling wave ultrasonic motors, and the behavior of the traveling wave and the elliptical trajectory of arbitrary points on the vibrating body were confirmed. *Note: Since Nastran does not have piezoelectric analysis capabilities, excitation was performed using force loading instead of voltage drive.* □ For other functions and details, please refer to the catalog.

【Case Overview】 Containers for storing liquids, such as water tanks and oil tanks, experience a sloshing phenomenon where the free surface of the liquid inside the container oscillates at relatively low frequencies when subjected to vibrations. In this analysis, we utilized the virtual fluid boundary and phantom elements of NX Nastran to analyze the characteristics when the bottom of the tank is excited in the horizontal direction. *Note: Fluid can be modeled without creating elements.* □ For other functions and details, please refer to the catalog.
