Within the last few years engineering analysis and optimization methods became more and more reasonable in the development stage not only of specialised high-tech products but also of industrial standard components and systems. This trend is forced by establishing simultaneous engineering concepts in R&D-departments. Acceptance of these methods in industrial practice goes along with increasing power of solution procedures as well as reliability and ease-of-use of software implementations.
This paper shows practical applications on the development of pneumatic actuators and control-components. Optimal design of cylinder housings and profile shapes as well as structural analysis and optimization of rubber elements with their non-linear structural behaviour due to hyperelastic material law, contacting surfaces and friction are discussed.
