Minimizing wrinkling through Wrinkling Simulation

Wrinkling simulation is a powerful tool for the early identification and optimization of potential weaknesses in seat cover design. It allows targeted prediction of areas with an increased risk of wrinkling and enables designers to minimize these risks by adjusting the design and fastening methods. This ensures that seat covers remain taut and evenly stretched.

Technology and methodology of Wrinkling Simulation

The Wrinkling Option in CASIMIR/Automotive provides an optimized workflow to accurately predict and minimize the risk of wrinkling in seat systems. A wide range of factors are considered:

Material Properties: Based on the specialized material cards developed in the Material Manager of CASIMIR/Automotive, the properties of the individual patches are modelled, considering the material orientation.
Assembly Simulation: The fastening of the covers to the foam (using clips and/or wires) and to the structure is semi-automatically generated according to the real production process. Additional tools assist in the efficient creation of contacts and the adjustment of manufacturing parameters for the individual areas.

Based on the results of the cover simulation, the risk of wrinkling can be derived using various criteria. By optimizing the fastening points and pre-tension, as well as the geometry of the patches, the risk of wrinkling can be minimized.

Combining Overbuild and Wrinkling Simulation for optimized vehicle seats

The combination of overbuild and wrinkling simulation provides the foundation for the optimal design and manufacturing of vehicle seats. This allows for adjustments in material selection, pattern design, and production processes, enabling the design specifications to be achieved with optimal fit and aesthetics. The results also serve as a basis for further simulations regarding wear or aging behaviour.
