Abstract: This paper discusses cranktrain system geometry generation and applications of a sequential quadratic programming (SQP)-based geometry optimisation for the rapid powertrain concept design assessment. This paper also presents the development of systematic approaches, geometric transformations and mathematical equations in the calculation of cranktrain component geometry. The procedures, methodologies and knowledge-based design rules for various components are implemented in Powertrain Engineering Tool (PET) developed at Ford Powertrain and Vehicle Research Laboratory. An example of computer simulation results such as rotating connecting rod path generation, connecting rod shank geometry optimisation, packaging, and related engine friction, will also be presented.

Keywords: knowledge-based design; SQP; geometry optimisation; packaging; friction; vehicle weight simulation.
