Research on the Design Method of a Bionic Suspension Workpiece Based on the Wing Structure of an Albatross. [PDF]
Appl Bionics Biomech, 2019 An air suspension platform uses air pressure to realize the suspension function during the suspension process, and it has the disadvantage of large air pressure and a small suspension force. In this study, an air suspension platform was built using bionic design to reduce the required air pressure and increase the suspension force.
