Abstract: As an essential research effort in developing a new cam drive engine, this study investigates a complex multi-objective cam shape optimisation problem for a unique cam mechanism in the cam drive engine. A uniform B-spline representation is developed to construct the cam shape. Moreover, an evolutionary multi-objective optimisation approach is applied to solve the problem. The optimisation results show that the overall engine performance is improved significantly by the evolutionary multi-objective optimisation approach compared to the initial design. In the meantime, the ease and flexibility of the optimisation approach in solving this complex cam shape optimisation problem are demonstrated.
