Abstract: The collapse strength of tubulars with recess patterns machined into their walls is an important topic for oil field downhole tools, especially in hollow carrier perforating gun systems. This paper presents a study of the ...

Abstract: The kinematics and dynamics of n(3RRlS) reconfigurable series–parallel manipulators (RSPMs) are the theoretical foundations for capturing noncooperative targets in space. In this study, a unified kinematic and dynamic ...

Abstract: Abstract. Space capture technology has become a key element of missions such as space-debris removal and in-orbit servicing. Many existing capture mechanisms struggle to balance structural stiffness and impact resistance. ...
