Abstract

The gripping force dependencies and compressed air consumption dependencies from the diameter of the smallest rounded nozzle section of air-jet gripping device with a flat active surface were investigated by numerical simulation using open source computational fluid dynamics (CFD) software OpenFOAM. Established that making rounded nozzle channel with constriction and extension of it at the entrance to the radial gap between the active surface of the air-jet gripping device and a flat object, provides a significant (52-56%) increase of gripping force with a slight (6-9%) increase in consumption of compressed air.
