Development design / CAE analysis / 3D modeling
This is an attractive job to create the future of mobility through the development and improvement of new vehicles. We offer the best services to play an important role in achieving sustainable mobility development.
Development design
By skillfully operating high-end three dimensional CAD “CATIA”, we design automobile parts that are delivered to users all over the world.
Work content
In design, we coordinate with related departments to determine the final product shape so that it meets the requirements necessary to realize the product.
To determine the shape, we use CATIA to model a shape that incorporates our own technology and ideas in a 3D space, and based on this, we repeat various studies with related departments.
We measure performance from various perspectives, such as compliance with the laws and regulations of each country, environmental performance and collision safety performance, and work as a team to derive a shape that meets all performance requirements.
Based on the wealth of knowledge, experience, and know-how we have accumulated over the years, specialists with high-level modeling skills are dispatched as designers, or entrusted or contracted for design work.

CAE analysis
It is the work to predict and evaluate the performance and behavior of products by computer simulation.
Work content
Automobile collision CAE analysis is to predict and evaluate the behavior and safety of automobiles when they encounter accidents or collisions using computers.
This makes it possible to evaluate the safety of the vehicle while minimizing actual collision tests.
In such analysis, the design, structure, material properties, collision speed, and angle of the automobile are first incorporated into a computer model.
Next, based on these information, the computer performs mathematical numerical calculations and simulates data on various factors at the time of collision.
We mainly support the evaluation of the following points as a collision CAE analysis.
- Model creation
Create a 3D model of the target car or structure on a computer. This model precisely represents the shape, structure, and material properties of the target object. - Structural analysis
Evaluate how effectively the strength and deformation of the vehicle’s structure and the design of the deforming space absorb impacts.
Occupant behavior analysis: Assess occupant safety by predicting how they will move and how much force will be applied in a collision.
Based on the results of these analyses, automobile manufacturers can optimize designs and improve safety functions to increase safety before conducting actual collision tests.
It also serves to streamline product development procedures, and save costs and time.
In addition, we have the following analysis work results.
- – POWER UNIT-related
- – Light assembly / Interior-related

Computer-Aided Engineering (CAE) software for analysis is a tool that utilizes computers to analyze the collision and collision-related behavior of structures.
These tools are useful for simulating the effects of physical collisions and forces in virtual space, for identifying problems during the development stage, and for optimal design.
Based on a CAD (Computer-Aided Design) model, input the shape of an object, material characteristics, boundary conditions, etc., and simulate actual behavior on a computer.
CAE software is used in a variety of industrial fields, including the automotive and aerospace industries, and contributes to improving the efficiency and quality of product design and development processes.
