[Case Study] Shape Optimization to Improve Natural Frequency ★ Detailed Materials Available

Control the natural frequency while considering the MAC value. Utilize parallelization to handle large-scale models in a short time.

By changing the shape, we improve the natural frequency and resonance frequency. Additionally, we have added conditions to allow for die-cutting in accordance with manufacturing requirements. In recent years, the performance of PCs has increased, and the scale of models required for finite element analysis has also grown larger. In such cases, significant time savings can be achieved by utilizing parallelization. This time, we performed shape optimization on a large-scale model with over one million nodes using parallelization. 【Analysis Model】 ■ Elements: Tetrahedral second-order elements ■ Number of elements: 653,931 ■ Number of nodes: 1,026,428 <Related Keywords> - Rib shape - Matching considering MAC values - Controlling eigenvalues *For more details, please refer to the PDF document or feel free to contact us.

Example: Warpage Countermeasures for Connectors in Injection Molding

By collaborating with 3D TIMON, we automatically adjust the thickness of the solid element model, thereby suppressing warping deformation.

Here is an example of minimizing warpage by changing the thickness of solid elements. The analysis was conducted using the "Basis Vector Method," which modifies the shape by moving the nodes of the finite element model without using CAD. Several patterns (basis vectors) of the desired shape were prepared from the initial model and combined. As a result of the optimization, the sum of squares of warpage improved by 33% to 4.9480e-004 compared to the initial shape, and the maximum warpage (mm) improved by 12% to 3.8607e-002. [Case Overview] ■ Optimization Conditions - Design Variables: Thickness A, B - Sampling: Initially LHS 20 points, Approximate optimal solution + 10 recommended points - Approximate Model: CRBF (Convolutional RBF) ■ Analysis: Basis Vector Method *For more details, please refer to the PDF document or feel free to contact us.

[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.
