Abstract

In this paper are presented the benefits of introducing a new original multidisciplinary methodology that integrates in a global homogeneous process the benefits of the state of the art of product development techniques, mechanical finite element analysis and collaborative teamwork strategies. For exposing this interdisciplinary and Holistic Product Development approach, a case study is presented, focusing on a re-design project of a pneumatic rack and pinion actuator for valve actuation, first time designed in 1984. During the project, developed focusing on teamwork activities, the benefits of an extensive use of simulation techniques have been exploited, for implementing the best design change proposals emerged thanks to the application of a Design-to-Value (DtV) process. Final objectives are to optimize the product weight and efficiency of the actuator, while maintaining high safety, reliability, and performances, and at the same time to simplify the design, with a reduction of components construction complexity. In a First step of the application of the methodology, the procedures and tools foreseen by the DtV process for fostering improvement ideas generation are applied. In a second phase, design techniques based on FEA (“Design by Analysis”) are going to integrate the classical verifications of “Design by Formulas”, used in the occasion of the first actuator design, obtaining a much higher level of accuracy confirmed by experimental validation phase. This new value-oriented design strategy, implemented with a sort of “secret ingredient” given by collaborative teamwork, allowed to obtain tangible benefits and introduce a totally renewed more efficient actuator.
