Engineering and FEM-analysis

We develop hydraulic cylinders that redefine performance, precision, and durability. This is made possible by our engineers and our close collaboration with research institutions.

One result of this is our deep-R technology.

Every day, we work on new solutions to take your hydraulic cylinders to the next level. Whether through innovation or the optimization and modernization of existing cylinder models, the use of FEM analysis enables our cylinders to become slimmer and more efficient.

Design and calculation according to the latest standards – Finite Element Method (FEM)

We use modern calculation methods and software to develop the optimal design for your specific application. With the help of the Finite Element Method, structural challenges can be identified, analyzed in detail, and effectively resolved.

FEM analysis is particularly useful where manual calculations reach their limits. Typical challenges include the following:

• Evaluation and optimization of the service life of your hydraulic cylinder (fatigue life, endurance strength)
• Requirement-oriented design of new constructions
• Analysis and provision of valid verification
• Welded construction
• Expansion under pressure load
• Precise detection of asymmetries

A FEM analysis alone is just a tool. Its true value is only realized through the expertise required to reliably interpret the simulated results and translate them into practical designs. This is exactly where our engineers excel.

The resulting evaluation makes the outcomes tangible: our engineers can identify at an early stage how the relevant cylinder components behave under load, where critical stresses occur, and where there is potential for optimization.

FEM-based strength verification according to recognized standards

The analysis helps avoid oversized designs while increasing safety at the same time. A detailed, FEM-based strength verification for your custom hydraulic cylinder can be provided on request, in line with relevant standards and guidelines such as DIN EN, FKM, or DNV.

This documentation records the applied load cases, boundary conditions, material properties, and safety factors, and evaluates the results in a transparent and comprehensible manner.

In this way, you receive an auditable basis for internal approvals, for your quality assurance, and for communication with customers, experts, or certification bodies.

Why FEM analyses are so important for hydraulic cylinders​

In hydraulic cylinders, the buckling behavior and stability of slender piston rods are often the main focus, along with complex support and clamping conditions and local stress peaks at weld seams, transition radii, or oil ports, which are often not adequately captured by simple calculation approaches.

In addition, operational load spectra and fatigue effects, especially in the area of mounting interfaces and hydraulic connections, have a significant influence on service life, so a combined assessment based on FEM stress analysis and fatigue life prediction is required to reliably evaluate the actual load-bearing capacity of hydraulic cylinders.

These are the benefits of FEM analysis for you

• 

  Safety

  Through computer-aided FEM analysis, nonlinear effects such as material failure, buckling, and instabilities can be investigated. These calculations demonstrate that our designs precisely meet the required safety standards. This analysis is particularly important for hydraulic cylinders used in cranes, as it verifies stability and reliability under maximum loads.

• 

  Cost savings and efficiency

  The FEM analysis enables optimization of the design in terms of resource use while maintaining or even increasing component strength and stiffness. It therefore also supports the development of lightweight solutions. In addition, you save time and resources in the development of prototypes.

• 

  Precision

  With the help of FEM analysis, precise calculations and simulations can be carried out – even for problems where traditional calculation methods reach their limits. This ultimately allows targeted optimization of geometry and lightweight design.

• 

  Innovation and insights

  Through the analysis of complex components and operating conditions, we can gain new insights and drive innovation – as we have demonstrated with our deep‑R technology.
