Response surface design of bellows parameters with negative pressure shrinkage performance
https://orcid.org/http://orcid.org/0000-0001-9972-839X
For the flexibility and safety of robot gripper. A double-chamber bellows actuator with variable stiffness is designed. Given the different air pressures in the inner and outer cavities of the bellows, the flexible mechanical claw can not only grasp objects conveniently, but also control the contraction speed of the bellows and improve the service life of the bellows. The number, depth and thickness of bellows are three independent parameters, which are the main factors affecting the displacement shrinkage of bellows. The experimental results are more effective for selecting the six-layer corrugated pipe model, which has a depth of 7 mm and a thickness of 0.9 mm The validity of the model is verified by finite element simulation and experiment, and the elastic deformation of bellows is analyzed. The correlation of three factors with displacement and stress under different response surfaces is analyzed. The results show that the number of bellows > depth > thickness, Box-Behnken design and response surface method can be effectively applied to the simulation experiment of bellows. Last but not least, the flexible bellows variable stiffness technology will be widely used in industrial and agricultural fields, and flexible mechanical claws can be freely configured to ensure that there is enough contact area to safely handle targets and avoid damaging products.
