Modelling of an Automotive seat structure with connections by using ANSA

You will be provided with an CAD model of an Automotive seat structure. Modeling of the same assembly will be done by extracting mid surface by Manual and Automatic methods and meshing the whole component by achieving all the mentioned quality criteria parameters. Connections will be deployed in order to prepare model for NVH analysis.

Importance of Modelling Seat structure with Connections

Car seat structure assembly is very complex assembly in any automotive. There are lot of components present in this assembly such as Armrest, Backrest with lumber support, Headrest, Seat base, Seat track, etc. These components are connected together by using many connections such as bolts, rivets, seam weld and spring elements. The same connections can be deployed in ANSA Software also for various analysis such as NVH, Crash, Durability and Structural Analysis. To perform these analysis, the first task is to discretize the part into finite number of elements which is called Pre-processing or Meshing. ANSA is used for pre-processing an automotive seat structure and make the model ready for NVH Analysis in this project.

  • Perform Geometry cleanup and checks
  • Extract the midsurface
  • Mesh the component with given Quality criteria
  • Deep understanding of Connections used for NVH analysis
