Abstract

Pneumatic flexible joints are widely used in agriculture, medical and environmental detection and other fields due to their advantages of flexibility and human-computer interaction safety. At present, the stiffness of the pneumatic flexible joint is insufficient and the driving ability is weak. Based on the principle of particle interference, a variable stiffness elastic shaft is proposed. The mathematical model of the variable stiffness elastic shaft is established, and the relationship between the stiffness and air pressure of the elastic shaft is analyzed, and the relevant experimental verification is carried out. The experimental results show that the elastic shaft has simple structure and good variable stiffness , and can be used as a variable stiffness part in bionic machinery such as agriculture, medical rehabilitation and service.
