Singularity analyses of manipulators are performed with great concern to avoid singular configurations in which the driving motors and related hardware may face great difficulty to drive the manipulator joints further or ...

he interaction dynamics between a number of railway pantographs moving in contact with an overhead high-tension conductor wire has been studied. The bases of the pantographs are subjected to harmonic excitation with different ...

The vibration of an infinitely long beam with a large axial tension under a point harmonic load moving at a uniform speed is studied to find out the importance of bending rigidity of the beam. It is found analytically that ...
