[Example] External Super Element 1

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

【Case Overview】 ■Product Name: NX 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 limited number of analysis specialists. There has been no pre- and post-processing tool that fully supports SE analysis, and the data creation process has been complicated, which has hindered its widespread adoption until now. Femap has started to support external Super Elements for Nastran from version 11. In this case study, we will use an assembly model from the Femap example collection to demonstrate that SE analysis can be used by anyone with Femap v11.

Example: Injection Molding - Simultaneous Filling of Multi-Cavity Molds

Example: Injection Molding - Simultaneous Filling of Multi-Cavity Molds

By collaborating with 3D TIMON, we automatically suppress variations and improve yield.

In general, even runners of equal length have different flow lengths for inner and outer paths, leading to filling imbalances. Here, we will introduce an example of optimizing runner diameter by integrating AMDESS and 3D TIMON* to improve filling balance. *3D TIMON is a plastic injection molding CAE software developed by Toray Engineering Co., Ltd. *For more details, please refer to the related links or feel free to contact us.

[Example] Generation of CAD model from topology optimization results of a chair.

Utilize the generated surface! It is possible to conduct verification analysis by generating a mesh.

We will introduce a case where we smoothed the surface of the shape obtained from topology optimization analysis and created a CAD model for verification analysis, as well as STL data for 3D printing. The generated curved surface can be treated as a solid body in CAD software, allowing for verification analysis by generating a mesh. Additionally, by outputting the STL data after smoothing the surface, it can be produced using a 3D printer. [Work Contents] ■ Initial STL ■ Fold settings ■ Editing of small holes ■ Smoothing ■ Editing of thin members ■ Generated curved surface *For more details, please refer to the PDF materials or feel free to contact us.

[Example] Topology optimization considering manufacturing requirements

[Example] Topology optimization considering manufacturing requirements

Initial design proposals and significant contributions to cost reduction! Introducing topology density variation limitation functions such as 'cross-section'!

Topology optimization is a method for determining the necessity or redundancy of materials (member layout) that contributes to lightweight and high-rigidity product design by seeking structures that maximize rigidity under a certain weight limit. While it allows for significant structural changes compared to the initial structure, it can also result in outcomes that are difficult to manufacture or lead to complex structures with high manufacturing costs. To avoid such situations, the topology optimization in 'OPTISHAPE-TS' utilizes a topology density variation limitation function, enabling optimization while satisfying manufacturing requirements.

[Column] The Theory of OPTISHAPE-TS: Norm Spaces and Inner Product Spaces

[Column] The Theory of OPTISHAPE-TS: Norm Spaces and Inner Product Spaces

Explanation of spaces where norms and inner products are defined! Introduction to a technical column.

In the previous article, we explained the concept of "space" in modern mathematics. The concept of a set exists as "a collection of specific things," and among those, we specifically call those that can determine some kind of relationship between the elements belonging to it "space." Additionally, we introduced "linear spaces" and "metric spaces" as concrete examples of spaces. In this article, we will further discuss spaces where norms and inner products are defined.

[Technical Column] The Theory of OPTISHAPE-TS: Sigmoid Function

[Technical Column] The Theory of OPTISHAPE-TS: Sigmoid Function

A thorough explanation of linear spaces, also serving as a review! Introduction to our company's technical column.

This time, I will discuss the idea related to the optimization problem of a function that takes values within a certain specified range, specifically focusing on the sigmoid function. When solving non-parametric optimization problems using the H1 gradient method, we consider that an initial value of the function, which serves as the design variable, is given, and we update the design variable by adding an incrementing term to it. Therefore, this function must be an element of a linear space. I will carefully explain the concept of linear space as a review. Please feel free to download and take a look.

■□Optimization, Weight Reduction, Cutting-Edge Seminar□■

We will introduce the usage, precautions, and examples regarding the structural analysis and optimization of advanced material utilization products.☆

The use of composite materials is being actively considered as one solution for product lightweighting. Challenges such as cost and recycling are also being overcome, and it seems we are finally entering the practical stage. However, without establishing techniques to simulate the strength, safety, and productivity of products using new materials, we cannot move forward. In this seminar, we will introduce the optimization of composites using Abaqus and composite optimization pre-software, topology optimization with Tosca, adjoint optimization solvers, and plastic injection molding simulation with Simpoe-Mold. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ ● Date and Time: June 30, 2016 (Thursday) 13:30~17:00 ● Capacity: 30 participants (first come, first served) ● Venue: Dassault Systèmes Tokyo Headquarters Seminar Room 2-1-1 Osaki, Shinagawa-ku, Tokyo, ThinkPark Tower (Reception on 20th floor) (3 minutes walk from JR Osaki Station) ● Application URL: http://www.cae-sc.com/events/keiryo-saitekika-seminar-201606.html

[Example] Free Surface Motion Simulation

[Example] Free Surface Motion Simulation

Analysis of the sloshing phenomenon when the bottom of the tank is excited horizontally using the virtual fluid boundary and phantom elements of NX Nastran.

【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.

[Case Study] Buckling Analysis of Thin-Walled Frame Structures

[Case Study] Buckling Analysis of Thin-Walled Frame Structures

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.

[Example] Optimization of Golf Club Heads

[Example] Optimization of Golf Club Heads

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. In this case, the key indicator is the initial ball speed at impact. In this example, we determined the optimal face thickness and shaft stiffness that maximize the initial speed under defined loading conditions (average golfer's power) using optimization methods. 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.
