Structural Analysis And Optimal Design Of Main Shaft Device Of Wrapped Hoist

Hoist is one of the most important types of mineral machinery, the safety of the Mineral well is directly influenced by the design level of the Hoist. However traditional analysis and design method can't meet the requirement of this complex product design. With the development of modern design method and theory such as CAD, optimal design, the design theory and method of the mineral machine is on its way to automation and intelligentization.Appling a subjective experience design to roller design,which makes to be subjected to illogical force,and then it can results in many disabled forms to roller,such as craze,dent,bolt snipping and so on.Even,this situation can brings on device fault, influences production and endangers hominine security.Therefore, according to the structural characteristic and working theory of Hoist, the paper adopts new structure of roller: thick shell and stretch branch.In the text, in the base of the theory of beam,we investigate the calculation of drum shell,branch wheel and the whole structure,and then create mathematical model.In the case of fulfilling geometrical restriction and functional control,the text puts up optimal research of hoist.the result ensure optimal location of wheel and accuracy of optimal design.Based on the sufficient analysis of its mathematical model, Combined object-oriented technology and data visualization technologyby, by use of development tool VC++6.0, a set of interface friendly, complete function optimal design software used for Wrapped hoist can be worked out.The design can apply to engineering practice, guide the design and development of products, improve the quality, level and competition of products and supply with modern design method in crane industry.
