Packaging design in 3-D CAD also includes a check of the assembly process with digital mock-ups. In a final stage, using rapid prototyping methods, mock-ups may be made from the CAD models to physically check the assembly and serviceability.
The 3D data for the packaging design, both from the engine compartment and the engine including accessories, can be obtained with 3D photography.
With new vehicle generations, the optimum packaging of the powertrain gets increasingly complex, as performance increases, installation space is at a premium, and air flow through the engine compartment is minimised to reduce air drag.
The piping for the intake air system, vehicle exhaust system including aftertreatment and silencer and for the cooling system is best optimised in an early stage of the vehicle design.
AVL's methodology aims to reduce development cost and time by using simulation. The focus is on product cost driven by component and assembly complexity, ease of service and repair, considering the modular engine / vehicle portfolio.
AVL has the collective experience of simulation, engine development, acoustic and driveability optimisation and production engineering, which has been applied in many different customer projects.
Our service is integrated into the development process of our clients. The typical phases of powertrain packaging start with data acquisition and the definition of the applications, then continue with simulation, the specification of components and subassemblies.
