    Application of Single Unit Impact Dampers to Reduce Undesired Vibration of the 3R Robot Arms 

    نوع: Journal Paper
    نویسنده : J.E.Jam; عارف افشارفرد; Aref Afsharfard
    سال: 2013
    خلاصه:

    In the present study, vibratory behaviour of a robot arm with a single unit impact damper is investigated. To find the contact duration, oscillation of the impact mass and the main mass between and during the contacts is formulated. Using...

    Suppressing Undesired Vibration of Robot Arms Using Impact Dampers 

    نوع: Conference Paper
    نویسنده : انوشیروان فرشیدیان فر; عارف افشارفرد; Anoshirvan Farshidianfar; Aref Afsharfard
    سال: 2010
    خلاصه:

    The behavior of a vibration system suppressed with an impact damper is investigated, where the impact damper is simplified as a combination of spring and viscous damping. The analytical answer for the contact duration is developed using iteration...

    Reliability-based Design for Damping Behavior of Inner Mass Single-unit Impact Dampers 

    نوع: Journal Paper
    نویسنده : عارف افشارفرد; فرهاد کلاهان; Aref Afsharfard; Farhad Kolahan
    سال: 2013
    خلاصه:

    In this paper, the dynamic response of a vibratory system equipped with a single-unit impact damper is analyzed. The reliability behavior of this system is investigated when the stress and strength are distributed lognormally. The standard deviation...

    Application of single unit impact dampers to harvest energy and suppress vibrations 

    نوع: Journal Paper
    نویسنده : عارف افشارفرد; انوشیروان فرشیدیان فر; Aref Afsharfard; Anoshirvan Farshidianfar
    سال: 2014
    خلاصه:

    In this study, ongoing investigations to apply piezoelectric materials as an energy harvester are extended. In doing so,effectiveness of single unit impact dampers is increased using piezoelectric materials. For this reason, barriers of the impact...

    Investigating Vibratory Behavior of Nonlinear Single Unit Impact Dampers Using Perturbation Method and Genetic Algorithm 

    نوع: Journal Paper
    نویسنده : J.E.Jam; عارف افشارفرد; Aref Afsharfard
    سال: 2012
    خلاصه:

    Applications of impact damper to reduce machine tools vibration have been investigated analytically, numerically, and experimentally for many years. The reason for this interest lies in the fact that impacts occur very often in many modern technical...

    Design of Nonlinear Impact Dampers Based on Acoustic Behavior 

    نوع: Conference Paper
    نویسنده : عارف افشارفرد; انوشیروان فرشیدیان فر; Aref Afsharfard; Anoshirvan Farshidianfar
    سال: 2011
    خلاصه:

    In this work, ongoing studies to investigate the vibratory behavior of nonlinear impact dampers will be extended by considering the acoustic properties of these systems in initial design of them. For this reason, mathematical model of the sound...

    Investigating Application of Impact Dampers Using Homotopy Perturbation and Genetic Algorithm 

    نوع: Conference Paper
    نویسنده : انوشیروان فرشیدیان فر; عارف افشارفرد; Anoshirvan Farshidianfar; Aref Afsharfard
    سال: 2010
    خلاصه:

    In different applications, optimal values of an impact damper parameters (impact mass, elastic coefficient of barrier etc.) should be found in order to damp undesired vibrations efficiently. The main target of this work is modeling and investigating...

    The incremental harmonic balance method for nonlinear vibration of autonomous self-excited oscillators with impact dampers 

    نوع: Conference Paper
