https://doi.org/10.13052/ijfp1439-9776.2125Keywords:
State of the art, Digital hydraulics, Switching Valves, Multi-chamber cylindersAbstract
This paper analyses the current state of the art in linear actuation with digital hydraulics. Based on the differences in their aims the paper partitions the area into four actuation concepts – parallel valve solutions, single switching valve solutions, multi-chamber cylinders, and multi-pressure cylinders. The concepts are evaluated based on accuracy and smoothness of motion, switching load, reliability, efficiency and the number of components required.
