AN ANALYSIS PROGRAM FOR VIBRATION MODES OF A LINK CARRYING SOLID MASS

This paper presents a study on the frequencies and mode shapes of a vibrating system. The system consists of a cantilever beam with a solid mass attached to the free end of the beam. Effect of the mass to the beam vibration is investigated by varying the three dimensionless parameters: mass ratio, inertia ratio, and offset ratio. By virtue of several useful software tools, an integrated program is implemented to obtain at ease the eigenvalues and the pertinent mode shapes. The problem studied represents many mechanical systems including those light-weight manipulators with payload.
