Finite element analysis (FEA): Working smarter from the start

Obviously, Engines are not built up around the cylinder head gasket. In practice, the opposite is true. Attention to product design combined with highquality materials is the basis for functional, reliable, high-quality head gaskets. Thinking beyond our competitors is a standard procedure at VICTOR REINZ: During the design phase, for example, we visualize the assembly sequence in the production line, and during repair work, we consider the packaging aspects. We also consider recycling issues and clean separation of the materials used.

A great amount of the development time – and therefore costs – required in the past can now be saved by means of component simulations in computers, i.e. simulated tests using virtual models. By the same token, practical experience positively influences the FEA programs at VICTOR REINZ. This continuous refinement of our computing models and simulations mean that our programs get smarter over time. The result: All relevant functional parts and critical areas of the entire composite structure of engine block, head gasket and cylinder head are examined in detail during the FEA calculations in the design phase, leading to optimum gasket development. The first step during FEA involves analyzing the clamped status of the entire engine block, including head, cylinder head gasket and head Bolts. After unclamping the structure, which corresponds to a setting of the Components, a realistic simulation is carried out, taking temperatures and ignition pressures into account. Similarly, all nonlinearities are considered, especially the resilience characteristics of the beads.

VICTOR REINZ developmental engineers think and work in conjunction with our customers' development departments. This leads to the high efficiency that gives our customers a leading edge, and permits our products to be adapted quickly to changing conditions.

Cylinder head gaskets from VICTOR REINZ not only fit into the engines, but also into the 3D computer-design worlds of our customers. We speak the same language as your designers, and supply the geometric data of the required head gasket in the specified data format, using the fastest available online data transmission methods.

We also differ from other suppliers by providing close-to-production tooling from the start. After the sheets have been coated on series production equipment, and the gasket contour has been cut with lasers, the beads of the head gasket are stamped with our embossing Tools. These tools are produced on our premises quickly and cost-effectively. Your advantage: Prototypes are of the same quality as the later series gaskets – with few deviations. Modern CNC-controlled measurement equipment ensures optimum quality monitoring. Subsequently, all relevant data are recorded in a technical document.

Scientific methods instead of chance: the application of FEA makes many empirical approaches superfluous during the design of a cylinder head gasket.

An entirely new level of quality for prototypes – made possible by VICTOR REINZ with close-to-production tooling.
