Abstract :
A new design of a machine is developed which performs contactless actuation in four axis - three translational and one rotational - with high accuracy. Remarkable on the concept is the moving part of the machine which is free of contacts, enabling free z-rotation. The components of the device are optimized for different requirements. The optimization algorithm is a combination of an evolution strategy (ES) and an approximation method based on the Response Surface Methodology (RSM). The design and optimization is supported by numerical simulations using the volume integral equation method (VIEM) combined with the fast multipole method (FMM).
