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. We survey customer requirements and turn them into producible solutions that are appropriate in terms of function. By using standard engineering methods, we develop robust system solutions for the customer application concerned. For this, we use results from the Simulation department, lessons learned and information from external suppliers and engineering service providers. 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. 3D CAD sectional model of a phaser Design as an interface Model design in the 3D CAD system During the next steps we transfer the sketch that exists at the outset is to a 3D data model along with the results from simulation, experiments and measurement equipment, in consultation with suppliers and the customer. For detailed design, we use standard 3D CAD systems such as PTC Creo 2.0 / 4.0 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 appropriate software support from programs such as MDESIGN. Amongst others 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 as well. Screw design in accordance to VDI 2230 in MDESIGN Calculation of leakage at clearances and identification of sensitive geometric dimensions 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 producible design, cost optimization and reliability. Depending on the length and complexity of the tolerance chain, we employ both arithmetic and statistical tolerance analysis – mainly with software support by the tools Cetol and Simtol. The tolerance analysis allows identifying the potential for optimization of robustness and costs and adapting them effectively. Statistical tolerance with the proportion of “good parts" Pareto chart of the contributors Drawings as the basis for communication The circle closes with the drawing 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 further, the drawings function as the common basis for the discussion of individual parts and assemblies with internal and external collaborators and, finally, manufacturing.
