Mismatch of dynamic vibration analysis result

Hiii,
I am analysing a fresh model for dynamic response. But the result is far from the original result. Can anybody suggest me why is this happening?

Hi,

Not running the case I suppose the boundary 16 does not point anywhere and the transient analysis leads to rigid body motion in space including rotation and translation?
