Fixed a linear connection type in SE Simulation

Linking is the mechanism that defines how to connect the desktop components to other desktop or to the surface. In assemblies you can determine interconnected surfaces, without the need for interconnection and their behavior model accurately. Use the links, you can perform the following tasks:

• to specify a fixed connection, for instance welded plates;
• compensate for bending of the parts and enter tolerance;
• compensate for the thickness of the space between the two plates.

Linking is actually another type of restriction, which allows you to control the behavior of components in the assembly model for finite element analysis.

When working in the simulation assembly, the user must tell the system which parts are analyzed and how they will react when subjected to force or pressure. During preparation, the user can choose the type of interconnection between components in the assembly. SE simulation offers two options- solid and linear connection type. These connections can be defined automatically or manually.
Below we used both options on the same assembly are shown different results.
In both cases the force to the right side of the upper block. Part is anchored the bottom of the block on the left.

Fixed connection

defining connection surfaces and prevents relative movement in all directions.

Linear connection

defines a sliding connection surfaces, depending on the forces between the elements (and frictional forces). The gap between the components may vary depending on the deformation change.

Keep in mind that the calculation of the linear connections requires a longer solution due to the number of internal steps necessary for an accurate result

Hard-wiring is used for all calculations NX Nastran
Linear connection is usable only in a linear static analysis

Solid Edge Simulation

 Simulation program designed for Solid Edge are based on proven technology finite element analysis based on NX Nastran (used in its development, for example, NASA). Significantly reduces the need for physical prototypes, thereby reducing testing costs while reducing design time. The user has a choice of several levels of calculations according to their abilities and needs. Unified model ensures portability defi ned constraints and loads between different levels of stress analysis solutions.

Solid Edge Simulation Express

  the basic output level for solving simple strength and modal (mode shapes and frequencies) tasks. Simple operation with a reliable guide gives correct results even for beginners. Basic level includes the automatic creation of networks of finite elements. They are supported by a network of tetrahedral elements to the bidirectional network střednicových areas of sheet metal parts. The finite element mesh can use the slider to change and improve the overall softness of the network to get a more accurate simulation model. Postprocessing is based on quick interpretation and understanding of the resulting model behavior, to help even complex visualization tools. Results can be displayed in a variety of forms, including models with color rendering and animation of results of stress or strain. Easily define problem areas and display units maximum / minimum stress and also generate a report with the final results. After analysis, you can quickly and easily perform all the required design modifications. Synchronous technology lets you make any changes to the model geometry without modifying historical dependence, which significantly accelerates the process of finalizing the model.

Solid Edge Simulation

  higher levels of stress analysis for engineers, compared to the level of Solid Edge Simulation Express is expanded to include a larger number of input and output data and calculation of buckling. If possible capable engineers to perform their own analysis, they can perform more analytical tasks in less time - the result is increased quality, cut costs and reduce the need for physical prototypes. Also, it avoids the high cost of analyzes by specialized companies. Solid Edge Simulation provides a full set of features for the defi nition loads and boundary conditions. All defi nition of boundary conditions, you need to create realistic models. Restrictive conditions are based on the geometry models and include fixed links, network connection, rotating custody, symmetry and straight bond. The loads are also based on the geometry and include both mechanical and thermal loads for thermal analysis. Solid Edge Simulation allows for load and boundary conditions defi pay options in the context panel to determine the direction and orientation of serving simple controls. For analysis reports can create contacts between the components of the report very quickly. There are contacts between the components, iterative linear solution, and glued joints. Contacts between the components can leave or find it automatically defi pay individually by selecting surfaces. The integrated NX Nastran allows for realistic interaction of components in the assembly robust iterative method. The finite element mesh can be improved by manually setting the size of the edges and surfaces of elements.
