Mechanical engineering: From the idea, simulation & prototype to series support

Assystem Germany provides engineering, test and consulting support in the mechanical and mechatronics disciplines. We offer system comprehension beyond the product detail and successfully implement projects from the idea and prototype to series support. We focus on the development and optimisation of components for lighting, body, interior, motor and motor periphery. We combine our extensive experience in vehicle quality with numerical simulation and physical test methods, for example to prevent and eliminate unwanted noises (squeak & rattle) in the vehicle.

Where we make the difference

  • Development and consulting for mechanical and mechatronics specialist disciplines, e.g. calculation and design of components, prevention of acoustic noises, analysis (component benchmark, dynamics, structure), joining technology, fixture construction, etc.
  • Our system understanding goes beyond the product and facilitates integrated processing - from the idea to a usable prototype from a single source
  • Vehicle hall with lifting platform and separate functional spaces, construction of prototypes, vehicle modifications, installation of measuring devices, etc.
  • Global expert network of the Assystem Group

Modules, body, motor & motor periphery
