Abstract

This paper presents a design methodology for optimal design of haptic devices, considering aspects form all involved engineering domains. The design methodology is based on parametric modeling, iterative and integrated design approach that leads to easier design space exploration for global optimal design and initial verification in the conceptual design phase. For global optimization, performance indices such as; workspace volume, isotropy, stiffness, inertia and control of the device were from all involved engineering domains were considered. To handle this complex and non-linear optimization problem, a multi-objective algorithm together with a new developed optimization function was used, to obtain a global optimum solution. A case study, where the methodology has been applied to develop a parallel haptic device is presented in detail in this paper. The results obtain from the test case model show significant improvements in the performances of the device.
