RISProbabilistic Method to Compute the Optimal Slip Load for a Mistuned Bladed Disk Assembly With Friction Dampers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, an analytical technique has been developed to compute the statistics of forced response of a mistuned bladed disk assembly with friction dampers (blade-to-blade or blade-to-ground). ...
Control of Multiagent Systems Using Linear Cyclic Pursuit With Heterogenous Controller Gains
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, behavior of a group of autonomous mobile agents under cyclic pursuit is studied. Cyclic pursuit is a simple distributed control law, in which the agent i pursues agent i+1modn. ...
