Sometimes complex structures and highly loaded components can not be calculated or optimized using conventional anlytical methods. Here Finite Element Analysis is helpful in solving these tasks efficiently with exact results and a minimum of experimental effort. FE-Analyses can also be used to solve thermal and dynamic problems.

KNOEPFLI  INEGNIEUR-DIENSTLEISTUNGEN offers to its customers simulations either for a dedicated simulation assignment or as a design tool in connection with a development project.

The Simulations are performed with Simcenter 3D of Siemens PLM Software. The solver used is NX-Nastran.

Aside from the creative work of finding solutions and designing the shape of components, every development project also involves dimensioning tasks. Many components are subjected due to its function to low loads or none at all, they can be dimensioned by good sense of proportion. Other components experience much higher loads, components in critical functions may under no condition fail and must have a long life span. It concerns commercial or self-designed machine elements and components for which standardized calculation methods or even calculation regulations exist.

KNOEPFLI  INEGNIEUR-DIENSTLEISTUNGEN  offers to its customers dimensioning and design calculations either for a dedicated calculation assignment or as integral part of a development project.

• Load determination of individual components
  
• Dimensioning of machine elements (bolt, shaft, gear, bearing, etc.)
  
• Design calculations of pressure equipment
  (Acc. to Pressure Equipment Directive (PED) and e.g. AD 2000 rules or EN 13445)
  
• Design calculations acc. to div. regulations (crane, elevator, etc.)
  
• Heat transfer calculations (div. media, w/wo evaporation)
  
• Drive dimensioning
  
• Process calculations (pressure loss, heat flow, etc.)
  

• Component dimensioning
  
• Proof of strength
  
• Pressure equipment
  
• Thermodynamic processes
  
• Cooling and heating calculations
  
• Drive technology
  
• Statics of steel constructions
  

Research departments work persistently on new technologies, materials and processes. Companies constantly expand their production plants or bring them up to the newest level of technology. New products are continuously brought to market, old ones are redesigned or are produced with new technologies.

KNOEPFLI INEGNIEUR-DIENSTLEISTUNGEN offers to its customers the phase-wise realization of complete design and development projects for new products or plants, their improvement or expansion.

• Planning
  
• Project management
  
• Market research, value analysis
  
• Design
  
• Design calculations
  
• Certification processing
  
• Detail design and drafting
  
• Procurement
  
• Testing and evaluation
  
• Installation and commissioning
  
• Product documentation
  

• Development of new products (capital and consumer goods)
  
• Re-engineering, re-launch
  
• Test rigs and infrastructure (R+D)
  
• Test objects and prototypes
  
• Production and process plants
  

If a company changes its CAD-system from 2D to 3D or to another 3D-Software, it is often necessary to transfer some of the existing designs to the new system with the purpose of keeping them up to date. 3D-models can be very helpful for the elaboration of brochures or product documentation. Photorealistic illustrations, explosion views or 3D-sections can be produced with them.

Temporary personnel shortage can prompt a company to make use of external services for the elaboration of drawings from particular designs.

KNOEPFLI INEGNIEUR-DIENSTLEISTUNGEN offers to its customers 3D-Modelling and drafting work independently of a development assignment (preferably with NX from Siemens PLM but also with other systems, i.e. SolidWorks, HiCAD).

• 3D-Models of individual parts based on existing manufacturing drawings
  
• 3D-Models of individual parts based on existing hardware
  
• 3D-Models of assemblies in different arrangements (i.e. exploded view)
  
• Port assemblies or complete machines acc. to internal modelling guidelines
  
• Elaboration of drawings based on a customer’s design
  
• Elaboration of manufacturing drawings based on sketches
  
• Elaboration of assembly and installation drawings
  

• Data transfer per software change
  Modelling per change to 3D-System
  Modelling of non-documented parts
  Brochures and Product documentation
  Relief of drafting personnel
  

• Participation in concept and design review
  Participation in brainstorming
  

• Operating manuals
  Installation manuals
  Brochures
  Catalogues
  

• No own manufacturing but in cooperation with specialized workshops for each manufacturing task
  
• Mostly in connection with a design and development task
  
• Pre-assembly and test at premises, final assembly at operation site
  
• Commissioning acc. to pre-defined procedures and acceptance criteria
