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

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

• Concept, design and construction of components – up to the series-ready system package
• Building space investigations
• Prototype construction and integration into vehicles
• Project management incl. data administration, control release process and change management
• Use of OEM tools

Lighting systems

• All services up to product development – starting with the first design drawing to production in small series
• Engineering and project management
• Prototyping
• Design/CAS modelling

Benchmark analyses of components & systems

• Procurement of vehicles and components
• Selection and procurement of measuring systems for comparison drives
• Benchmark analysis in Assystem workshop

Dynamics analysis & simulation

• Vibration stress, fatigue strength
• Simulation of shaker tests (vibration profiles)

Linear & non-linear structural analysis

• Strength
• Kinematics
• Assembly simulations

Mechanical test benches

• "Custom-made" test devices according to customer requirements, e.g. for motor components, sensors
• Design, layout and construction of the test benches
• Operation of test benches

Noise simulation / acoustic engineering

• Squeak & rattle / noise, vibration, harshness (NVH)
• Analysis of unusual sounds (cause, boundary conditions) in the vehicle
• Derivation of optimisation measures
• Redesign of critical components
• Software solutions used (Abaqus, Nastran, Edware,…)
• 1D / 3D acoustic measurements
• Training & consulting

Thermal analyses

• Thermomechanics (thermal tensions)
• Heating up / cooling down / heat reduction
• Flow simulation

Fixture construction

• Construction, production and assembly of production and assembly devices, e.g. press-in devices

Joining technology

• Screw connections: Standardisation, optimisation, layout, calculation, evaluation and verification according to VDI2230
• Application of national and international standards for safety-critical screw connections in Category A according to VDI 2862 considering OEM-specific standards
• Focused design improvement of mechanical connection / connection elements.
