E ngineering T echnology A ssociates. A sia P acific M iddle E ast. It has following functional modules: Springback and Springback Compesation. Blank and Trim Line Development. It can accurately predict wrinkling, cracking, rebound, stress problems, surface defects, BHF, press tonnage, and so on. We can parameterize equivalent drawbead in the CAE model to make it into a solid shape drawbead.

The mesh information of the solid bar can be used for simulation; the user can export the solid drawbead directly to the CAD software catia, UG, etc. The real rib simulation is more consistent with the actual forming state, which provides a reliable guarantee for springback prediction and springback compensation. Baosteel provides 9 categories of material parameters for all grades of sheet metal. Material library contains detailed parameters like stress-strain curves, FLC and so on. It is found that the Bauschinger effect has a significant impact on the forming and springback of ultra-high-strength steels such as DP and TRIP steels.

The accurate material yielding trajectory combined with the non-linear isotropic-follower reinforcement material model can greatly enhance the forming and springback prediction of the accuracy. As shown in the figure, using DYNAFORM to calculate DP springback using isotropic strengthening and isotropic respectively – follow-up to strengthen the material model, the contrast can be found to use isotropic – follow-up material model after a lot of rebound volume.

After ensuring the process stability, whole processcan be carried out after the simulation. Main Features Blank Size Engineering: Curve surface creation and editing capabilities are provided. BSE- Modular two pieces of material: BSE- Tailor – welded blanks.

ETA/Dynaform Sheet Metal Simulation Software

Reverse Three Dimensional Trimming line: According to the key point of material utilization, adjust the blank size, size of 3D inverse boundary line and provide basis for the product block evaluation and improvement of material utilization rate.

BSE automatic forming reports. BSE-Supports the formation of nesting, drawing layout, mixed layout. You can manually drag and drop to adjust the nesting results: Tailor Welded blank layout: BSE- Stamping direction adjustment, automatic and manual, convenient, support for the single-piece, two-mode, variety of stamping process conditions.

Rapid batch analysis can be carried out in batches; batch start and batch layout feature. It can analyze complex stamping process in the industry which includes springback and springback compensation and it is known for high precision era the world. In the early stages of product development and mold development, springback analysis provides the basis for product design, as shown following example: Accurate springback analysis provides basis for the product and mold development.


Especially in the case of high-strength steel, accurate springback analysis is very important. Product springback larger circumstances, relying on the mold process and structure has been difficult to produce products to meet the demand, so the current springback compensation is an indispensable tool in the development of mold means.

Springback Analysis and Springback Compensation Case: The method of iteration is used to optimize the dimension of the sheet. The original blank is automatically corrected during the iteration to obtain the exact product shape, and the product shape ultimately matches the target trimming line.

Example is shown below. You can also optimize multi-step and sideline: In the NC simulation of the bend, you can automatically calculate the tube centerline; according to the shape of the elbow after the automatic production process bend; can automatically generate the necessary tools for bending process.

Bend cynaform interface, and tool parameters are as follows: Tube Forming Simulation Case: Die structure analysis DSI: Stamping force Can be mapped to the die structure for stress, strength, fatigue analysis, thus optimizing the structure.

The entire production line can be simulated; can also simulate part under the dynafkrm of the deformation of the robot. In order to improve the safety performance of vehicles and weight requirements, models having more and more hot-formed parts are being used. Hot-Forming analysis can simulate the most advanced hot stamping process, including: The following example shows the result of hot stamping of the patch: Hot Forming analysis can accurately simulate the hot stamping process of wrinkling, cracking, thinning and other issues.

Common with high-strength steel plate of negative clearance, or small rounded forming, or thick plate forming are not suitable for general stamping simulation of the shell unit, in which case the sta of the shape of the springback, will be seriously affected. You need to try new cell types or new cell algorithms, such as solid units or the thickness stretch shell unit that takes into account the normal stresses that cause material thinning.

Using volume elements forming slabs bear fruit and resilience: The simulation results show: The central opening is Not only supports the use of volume simulation sheet metal forming, but also supports the use of volume simulation tube forming.

Hardening of Steel at two temperatures. Transformation induced by different initial plastic strain. Air-conditioner shell forming analysis wrinkling. Now in automotive design, the use of simultaneous engineering, and product design to take into account dunaform initial product formability, technology and other factors. Apart from experience, the use of tools is already eat product design stage to assess the product’s main means of formability.

Unreasonable product design, timely design changes.

At the same time the results of the analysis can be used as a mold to make the process quick reference module design process mold surface as a research product formability basis to become a reality. It provides widely recognized in the automotive stamping the SE. During stamping die outsourcing, consider the module material cost, mold quotes provide a great convenience. Mold Factory program to help determine the process, the analysis may appear in the mold problem: Timely adjustment of process technology solutions and modulus.


In the process of determining the process parameters: Tonnage, lubrication, clamping conditions. Mold structure is reasonable, and die fatigue analysis.

Some mature users, even without debugging mold, which can be opened. DYNAOFRM is widely used in household appliances such etq kitchen utensils, air conditioners, refrigerators, televisions and other fields.
