This paper will focus on the development of a new methodology and its accompanying innovative tools to aid machine designers during the conceptual design process of their electrically driven positioning machines. In other words, transforming the functional requirements of the customer into optimal machine concepts using three steps. First, the functional requirements will be converted into multiple feasible concepts using a model library. Second, CAD model information is incorporated in an analytical model to determine the objective values (e.g. root-mean-square torque TRMS) from the design parameters. Last, for each feasible concept, the motion profile and geometry are optimized to allow a fair concept comparison. Throughout this paper, a pick-and-place machine case study will be used as a guide to clarify this new methodology. Based on the customer’s needs, both a ‘fourbar’ and a diamond-shaped ‘fivebar’ linkage mechanism are created using the concept generator and subsequently optimized, where results show a significant reduction of up to 80.0% in TRMS.

摘要

This paper will focus on the development of a new methodology and its accompanying innovative tools to aid machine designers during the conceptual design process of their electrically driven positioning machines. In other words, transforming the functional requirements of the customer into optimal machine concepts using three steps. First, the functional requirements will be converted into multiple feasible concepts using a model library. Second, CAD model information is incorporated in an analytical model to determine the objective values (e.g. root-mean-square torque TRMS) from the design parameters. Last, for each feasible concept, the motion profile and geometry are optimized to allow a fair concept comparison. Throughout this paper, a pick-and-place machine case study will be used as a guide to clarify this new methodology. Based on the customer’s needs, both a ‘fourbar’ and a diamond-shaped ‘fivebar’ linkage mechanism are created using the concept generator and subsequently optimized, where results show a significant reduction of up to 80.0% in TRMS.
