Simulation
Design for the right solutions
It all begins with a sketch –
From the contract specification to the product
Design is the foundation and core of efficient, cost-effective development of our products. Customer requirements are collected, evaluated and implemented into manufacturable and functionally suitable solutions. In collaboration with our colleagues in the Embedded Systems department, we combine mechanical and electronic elements. By using standard engineering methods, we develop robust system solutions for our customers.
Our products meet demanding and diverse requirements at the same time. At the start of the design and development cycle, the aim is to transfer the individual requirements from the contract specification to the internal target specification and extend them as required. These then have to be assessed and turned into initial concepts. Many years of experience feed into this, as do new ideas for continuous optimization of our systems.
Design as an interface
Model design in the 3D CAD system
The sketch that exists at the beginning is transferred into a 3D data model. The models are refined with the help of the in-house simulation department and external manufacturing specialists.
For detailed design, we use standard 3D CAD systems such as PTC Creo and Siemens NX. For the exchange of the datasets, we use customer- and job-specific interfaces.
Sizing and design
The dimensioning of needed machine elements according to the relevant standards and directives is achieved with software support from programs such as MDESIGN. Among many other calculations, we perform calculations for screw design, to design the bearing points and identify sensitive geometric dimensions related to internal leakage. For detailed calculations and more complex geometries, we use results from simulation.
Achieving your objectives with the right tolerances
Component and cost optimization through tolerance analysis
Defining appropriate tolerances plays an important role in the balance between a producible design, cost optimization and reliability.
Depending on the length and complexity of the tolerance chain, we employ both arithmetic and statistical 1D and 3D tolerance analysis – mainly with software support by the tools simTOL and CETOL 6σ. The tolerance analysis identifies the potential for optimization of design robustness and cost savings.
Drawings as the basis for communication
A result of the product development process
At the end of each development stage, we record the design in a conventional 2D drawing including all of the dimensions, tolerances and other specifications that are necessary for the product. In the future, the drawings function as the common basis for the discussion of individual parts and assemblies with internal and external collaborators and, finally, manufacturing.
We like to keep it personal!
