Bond graph simulation of error propagation in position estimation of a hydraulic cylinder using low cost accelerometers
(2018-10-01)
Article
Accés obertThe indirect calculation from acceleration of transversal displacement of the piston inside the body of a double effect linear hydraulic cylinder during its operating cycle is assessed. Currently an extensive effort exists ... -
A simplified methodology to evaluate the design specifications of hydraulic components
(Multidisciplinary Digital Publishing Institute, 2018-09-11)
Article
Accés obertThe fatigue of a hydraulic component inherently varies due to various factors that can be divided into two categories: structural and load spectrum variability. The effects of both variabilities must be considered when ... -
Additioning alfa fibres in cement mortar
(Universidad Católica de Chile (UC), 2018)
Article
Accés obertCement mortar is a broadly used construction material. Adding fibres into the fresh mortar is an effective reinforcing technique to overcome the drawbacks related with the little tensile and flexural strength. Using natural ... -
