In order to achieve a normal performance of the armature, which is a moving part carrying currents in a railgun, it is of great importance to maintain good electrical contacts between the armature and rails. In this paper, based on mutiphysics effects, a dynamic interior ballistic process considering the friction loss, nonlinear electrical contacts, and aerodynamic drag is established to simulate...
Collaborative robots share the same workspace with humans, and it is inevitable that the robot will contact with humans or environments, so the importance of robot collision detection and end-effector contact force estimation has been receiving much attention. The conventional collision detection methods are based on extra sensors, which are not only increase cost but also increase the complexity...
