The thermal‐oxidative aging (TOA) and tribological properties of rubber had attracted attention in the petrochemical field. In this study, the mechanical and tribological properties of defect‐free, Stone–Wales (SW), and single adatom (SA) defective carbon nanotubes (CNTs)/nitrile butadiene rubber (NBR) composites were investigated using molecular dynamics simulations. Poly (1,2‐dihydro‐2,2,4‐trimethyl‐quinoline)...
In this paper, a method to improve the operating experience of master manipulator which is used to manipulate the slave manipulator is proposed. The general method to improve performance is compensating the gravity and friction of the manipulator. For the general method, not only the modeling of the gravity but also the identification of friction parameters imports errors. When the manipulator is...
In this paper, we built a Lagrange dynamical model for an interactive master manipulator based on Delta parallel mechanism. Genetic Algorithm was used to identify the static parameters in the LuGre friction model with regard to high non-linearity friction torque of the driving parts. The Stribeck curve relating rotational velocity with static friction torque for each driving part was obtained. To...
