Consulting
for
your
in-house
knowledge

The knowledge of methods and processes in the field of lightweight designs is our core competency. With ELiSE Consulting we would like to support your business with introducing and establishing innovative approaches and procedures in your enterprise.

Feasibility Analysis

Which components or units are suitable for bionic lightweight designs? Which parts exhibit the highest lightweight design potential? Where can alternative production methods or material changeovers cut costs effectively? We help you to find the right answers to your questions.

Methods & Procedures

We can advise you on applications of various CAE-software solutions. Our knowhow stretches from interpreting topology optimization results to automated couplings of all common CAD and FEA-tools as well as inter-divisional process designs.

Workshops

We offer you profound knowhow for bionic lightweight designs in the framework of this unique product development process. Tools for developing and optimizing technical components are applied in theory and praxis in order to utilize the acquired skills directly on your own product.

Concept
for
radically
new
ideas

Components that are continuously improved, will eventually reach their limits. We enable you to develop radically new concepts by following nature’s example, which set new standards for your product, realize completely new ideas and adopt unconventional solution approaches.

Specifications

At the beginning of every project we determine relevant specifications in close cooperation with the client by setting basic parameters for the development of new concepts. In general, the available space, the material, load cases and the manufacturing process need to be defined in order to start a target-oriented development process. Furthermore, objectives for your product such as weight reduction, performance improvement, functional integration or the minimisation of costs are determined.

Analysis

In a preliminary investigation of the component FE calculations are performed, considering all relevant load cases. These calculations serve as a reference for newly developed concepts and enable a deeper understanding of the mechanical behavior of the component. Within the framework of the component analysis, first results of topology optimizations can give further indications on sensible load paths, providing guidance in the following screening process.

Screening

After the component analysis biological archetypes and principles, that possess suitable lightweight structures, are sought. Here we can resort to a lightweight structure database with more than 120.000 plankton organism and prepared mechanical active principles. By using this immense storage of innovative lightweight structures, you can benefit from principles that have been optimized by nature over millions of years.

Concept Development

The determined active principles and constructions of the screening process are merged into one or several overall concepts. An appropriated analysis of these concepts with predetermined specifications allow a proper dimensioning and assessment of the applied lightweight principles with their impact on your component. Thus, innovative concepts are developed that enable your products to stand out from the competition. These concepts can be visualized in the form of drawings, CAD models or rapid prototyping models. Preliminary FE calculations enable predictions on the performance and offer a comparison to your reference component.
ELiSE
Engineering
for
an
optimal
component
design

ELiSE Engineering offers you a wide spectrum of engineering solutions. A strong interconnection of the construction, calculation and optimization provides excellent conditions to develop efficient and client-specific lightweight solutions.

CAE

For the CAD construction we attach great importance to a model structure with variable parameters. This approach suitable for simulation and optimization respectively later allows a bidirectional data exchange with FE and optimization programes. Depending on the requirements, the verification is carried out with static and/or dynamic analyses as well as crash and multiple-body simulations. Therefore the final design represents the requirements of the specifications and the client-specific expectations concerning an optimized lightweight design. When adapting to manufacturing restrictions, we also factor in additive production processes (ELiSE AM) next to established procedures.

Optimization

Already at the beginning of the development process we use topology optimization as a method to determine optimal load paths. The most comprehensive step during optimization is the parametric optimization. Coupled to CAD, discrete parameters such as the amount of ribs, as well as continuous parameters such as wall thickness or the orientation of surfaces can be modified iteratively. Through evolutionary algorithms, the natural improvement process is represented in technical form. Therefore the optimal parameter values for a given load spectrum can be identified. Furthermore, the concepts defined in the ELiSE concept are dimensioned to reach the optimum. Based on distinct research results, adaptive honey-comb structures are utilized to create finely branched and load specific stiffening structures. These structures are aligned according to an algorithm based on natural models. The use of topography, thickness and beads optimization give your product the finishing touch.

Automation

We are convinced that the two areas design and calculations, which are often treated separately, strongly influence one another in a bidirectional way. This effect is especially severe as soon as a strongly optimized lightweight structure is required. For a coupling between CAD, FE and optimization systems, mainly own developments are deployed next to commercial interfaces. In this way our expertise is applied in the area of programming e.g. the application for the automation of development processes and the coupling of CAD and FEM with the optimization system.

components

A successful implementation of your product with additive manufacturing requires a close connection between design and production processes. ELiSE AM reveals the full potential of bionic lightweight structures in conjunction with the emerging additive manufacturing technologies.

Construction

We give you the possibility to explore and transfer the powerful complexity of natural lightweight structures into your product. Create and build like nature and make your product line with bionic lightweight designs and additive manufacturing methods more efficient than ever before.

Bionic Algorithms

For an automated transfer of natural constructions methods to technical systems we count on our in-house developed algorithms. We can optimize and improve your product with bionic reinforcements, e.g. load-optimized honeycomb or load-dependent lattice structures.

Material & Production

Due to our long-term expertise in the production-oriented design of AM components and our broad network of manufacturing partners, we have a thorough understanding of AM processes and are able to design your AM product with a high process reliability.

Bionic Bike

We are convinced that a close connection between construction and calculation tools paves the way for better products. Our “Bionic Bike” is the outcome of the entire ELiSE product development process. In the design process established engineering methods were used; amongst others, powerful topology optimizations to reveal critical load paths, parametric optimizations with evolutionary algorithms to find the proper frame geometry with varying cross sections and wall thicknesses, as well as CAO to decrease notch stresses. Furthermore, the integration of adaptive lattice structures ensures an additional reinforcement in highly loaded areas inside the frame. These fine-tunings and the transfer of mechanical principles inspired by lightweight structures of diatom shells led to the development of an outstanding product.
