چکیده
|
In this study, the dynamic response of a timoshenko beam under movingmass is investigated. to this end, vectorial form orthogonality property of the timoshenkobeam free vibration modes is applied to the eem (eigenfunction expansion method). theimplication of the vectorial form series and an appropriate inner product of mode shapesin combination are focused for a beam with arbitrary boundary conditions. consequently,signicant simplications and ecacy in the utilization of the eem in eliminating thespatial domain is achieved. in order to comprise validation, the present study is comparedwith the det (discrete element technique) and the rkpm (reproducing kernel particlemethod).
