Chatter is a critical factor limiting productivity and efficiency in machining processes. Cutting tools significantly impact chatter stability, as they often serve as the most flexible component. The influence of cutting tools on chatter varies depending on their design and cooling mechanisms. Internally cooled cutting tools, commonly used in indus...
Over the past two decades, inerters have attracted significant attention in structural control. Numerous applications in engineering fields have proposed employing inerter-based control devices to mitigate structural vibrations. While theoretical studies have demonstrated performance enhancements, practical implementation and experimental validatio...
Vibration is a major issue during machining leading to short tool life and poor surface finish. Chatter occurring due to cutting tool flexible is a prominent issue in milling operation. Vibration absorbers have frequently been studied to suppress vibration and chatter during machining. Their practical applications have mostly focused on boring bars...
Chatter is one of the major issues that cause undesirable effects limiting machining productivity. Passive control devices, such as tuned mass dampers (TMDs), have been widely employed to increase machining stability by suppressing chatter. More recently, inerter-based devices have been developed for a wide variety of engineering vibration mitigati...
The role of inerter-based devices has generated considerable interest in terms of suppressing the vibrations in machines and structures. The inerter is a mechanical device that generates force proportional to the relative acceleration between its terminals. Recently, it has been shown that inerter-based dynamic vibration absorbers (IDVAs, for the m...
In this paper a new design for a small scale inerter-based dynamic vibration absorber (IDVA) is presented, based upon a pivoted-bar mechanism. There are several new innovations in this study. The first is to design, build and test an inerter-based device that does not need to be grounded, or placed between different parts of the structure in order...
This study investigates the effects of parasitic mass on the performance of inerter-based dynamic vibration absorbers (IDVAs). IDVAs have been increasingly employed to suppress vibrations in applications of civil engineering structures and vehicle suspension systems. While the masses of the components in a traditional dynamic vibration absorber can...
This study proposes a novel approach to increase the chatter stability in machining operations. It shows the potential performance improvement when an inerter-based dynamic vibration absorber is employed in a machining operation. Tuned inerter based devices have been employed to decrease the magnitude of the vibrations in applications such as civil...
Flexibility of links and joints affects dynamic behavior of manipulators. In this work, the vibration characteristics
of a one-link carbon-fiber box manipulator with a rectangular cross-section and a [0/90/0/90]
lay-up are studied to examine the effects of the link and joint flexibility. The theoretical results supported
with experimental studies a...
Abstract
Composite materials have been became widespread robotic applications. Manipulators having higher payloads can be produced by using lighter composite links. Payloads and dimensions of composite manipulators cause unwanted vibrations due to the flexibility. Unwanted vibrations can be attenuated by applying active or passive control methods....
