Powertrain Structural Performance
Summary
These include reducing the size and mass of the engine and its connected components, as well as designing for lower viscosity oils, direct fuel injection and increased cylinder pressure. Simulation plays an important role in helping engineers to design a powertrain for optimal efficiency and performance, as well as in ensuring that no reliability or durability problems are caused by combustion chamber pressure, temperature, or the rotational or translational speed evolutions of the parts. The realistic simulations provide crucial information such as bore distortion, bending stiffness, load distributions, stress fields, and fatigue safety factors. With concerns about vehicle emissions and fuel efficiency being priorities for automobile manufacturers right now, better powertrain design through simulation presents an opportunity to improve upon both without sacrificing time or money. Design improvements can be virtually prototyped to reduce or even eliminate physical test failures, and powertrain system behavior can be accurately predicted using high fidelity models.
