SOLID MODELING AND STRESS ANALYSIS OF THE LOWER SHEAVE ASSEMBLY
The lower sheave assembly is a series of elements that make the whole, over which load is transferred from the hooks on the crane. Taking into account responsibility and consequences of these elements (injury of people and economic damage from the fall of cargo) that are possible in the case of a collapse of the element or assembly as a whole it is quite justifiable request for a detailed scrutiny of their validity and security. Classical (conventional) methods include the making of necessary number of prototype elements, which after computation checks are additionaly analysed what includes certain economic and time costs. This paper gives an overview of geometrical modeling of parts and the formation of the lower sheave assembly in CAD/CAE software CATIA V5. Engineering (stress deformation) analysis of carrier sheet metal is made. The aim is to present the methods that provide additional security at the planning and contribute to faster and cheaper development of new products.
