Abstract
In this paper,two-dimensional drawing software AutoCAD is used for the design and drawing of upper and lower beam which are on the land side of 1200 tons / hour ship unloader .The wheel pressure of the whole machine under the action of gravity and wind load is caculated and checked in every work conditions. The stability of the whole machine is checked under several limit conditions. Subsequently, the finite element analysis software Ansys is used to calculate the strength,stiffness,stability of the upper and lower beams on the land side.
After checking, the stability of the ship unloader and the stability ,strength and stiffness of the upper and lower beams on the land side can meet the requirements.
Key Words:stability of the whole machine;beam;stability;strength;stiffness
