Optimising slew torque on a mining dragline via a four degree of freedom dynamic model

Computed-Torque Control of a Four-Degree-of-Freedom Admittance Controlled Intelligent Assist Device

Robots are used in different applications to enhance human performance and in the future, these interactions will become more frequent. In order to achieve this human augmentation, the cooperation must be very intuitive to the human operator. This paper proposes a computed-torque control scheme for pHRI using admittance control. The admittance model is first introduced. Then, the robot identifi...

a study on insurer solvency by panel data model: the case of iranian insurance market

the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.

Modeling, simulation and analysis of a multi degree of freedom aircraft wing model

This paper presented methods to determine the aerodynamic forces that acton an aircraft wing during flight. These methods are initially proposed for asimplified two degree-of-freedoms airfoil model and then are extensivelyapplied for a multi-degree-of-freedom airfoil system. Different airspeedconditions are considered in establishing such methods. The accuracy of thepresented methods is verifie...

Free Vibration Analysis of a Six-degree-of-freedom Mass-spring System Suitable for Dynamic Vibration Absorbing of Space Frames

This study is concentrated on the natural frequencies and mode shapes of a simple three-member space frame coupled with a dynamic vibration absorber. The dynamic vibration absorber is modeled as a six-degree-of-freedom mass-spring system. For the first time, the free vibration of an elastic structure with a six-degree-of-freedom mass-spring system is found. Each member of the space frame has un...
