Proposing our optimum solutions for lighter-weight and competitive price by Model Base Development

With our earlier involvement in our customer's vehicle development activities, our product development covers designing and testing.

① Concept designing

Build the concept of the ideal structures and frameworks which meet the customer's requirements by use of topology optimization method.

② Detailed designing

Designing the optimum structures and shapes with fostering performance, reliability, and productivity, and conducting cost study.

③ Desktop evaluation (CAE)

Desktop evaluation, including modeling, strength analysis, and forming analysis, to achieve the targeted properties for the structures and workability which meet the required performance.

④ Prototyping

Manufacture prototypes in house with the mass-production- process-simulated equipment and validate for product designing and quality build-up for mass-production.

⑤ Testing

Validate designing by bench-testing simulated to the actual vehicle motion. The test results are fed back to the designing. Model Base Development is made with the correlation between the desktop evaluation and the actual performance.

Cold forming simulation

Stress simulation (Forming simulation)

Analyzing the stresses remaining after forming enables identifying and controlling the stresses to make products with the spring back minimized.

Die structure simulation

Deflection of die tools happening when forming causes the dimensional defect of parts. Optimize the die structure by simulation of die rigidity to avoid such deflection.

Combined simulation

Combination of stress simulation with die structure simulation enables stress simulation considering die's behavior during stamping. This desktop evaluation assuming the situations with the actual machine can enhance the products' dimensional accuracy.

Hot Forming Simulation

Prediction of Temperature

We analyze and on-the-desk study for hot stamping process, which can produce high-strength parts by quenching and rapid-cooling the heated workpieces. We anticipate formability including possibility of cracks and wrinkles on the workpieces by simulating the material property which varies depending on temperature. We also anticipate the cooling performance and hardness by simulating the heat transfer between workpiece and die.

Forming allowance verification

Measure deflection in the whole surface of press formed parts. Map the measured values digitally to draw FLD with which the forming allowance against cracks are observed.Mitigate the defect risks by improving the forming surface of the area indicating less allowance.

Digital PCF

We check the joint area of the mating parts with 3D scanned product data, which enables us to observe the interference and clearance in the mating surface visually and to quantify the correction. This activity contributes to reduction of die modificiation frequency and time.

By reproducing movements of robots and equipment on a computer, design of the equipment or jigs are validated.
