The Mechanical Department provides a complete engineering
offer for product design  :

• Design :

• CAD, 3D modeling, 2D drawing, reverse engineering, concept design
• Technical specifications, project management, product design

• Numerical simulation :

• Meshing and assembly,
• Structural analysis: non-linear, fatigue and durability, thermo-mechanics, NVH, non-linear analysis
• Fast dynamics : crash calculation, high strain, biomechanics,
• Fluid dynamics : aerodynamics, hydraulics, energetic, combustion, fluid / structure interaction,
• Modeling of multi-physics systems : mechanical, hydraulics, .control, …

• Physical validation :

• Prototyping,
• Test benches : vibrations, endurance, mechanical durability,
• Wind-tunnel and aeraulic testing,
• Engine test.

This activity has secured major partnerships with manufacturers and suppliers within the transportation industries, especially in automotive fields : powertrain, engine component, chassis, interior and exterior equipment, safety, …

Projects examples :

• Cranktrain design and analysis
• Mechanical dimensioning of a rear bumper,
• Dashboard design and crash analysis,

• Aeraulic optimisation of air ducts,
• Thermomechanic study of exhaust manifold,
• Hydraulic and thermic optimisation of air heater unit,
• Aerodynamic characterisation and optimisation of a vehicle,
• Dynamic modelling of rocking parts,
• Study of noise generation during engine strokes,  
• Setting up of tests for crash validation. 

Thanks to its experience in project management, B2i is able to carry out complete mechanical developments in its research department in France and abroad.Last but not least, B2i have reinforced its global offer by creating a Joint-Venture with Tooltech, an Indian company specialized in mechanical development and remote engineering http://www.tooltechsoft.net/).
