METHOD FOR ANALYZING STRESS OF CRANE ACCORDING TO STRUCTURAL PARAMETERS

Disclosed in the present invention. is a method for analyzing stress of a crane according to structural parameters. The method includes the steps of selecting a crane type, and inputting parameter data of each structure of the crane; establishing a three-dimensional model of each structure of the crane according to the input parameter data; assembling the three-dimensional models of various structures of the crane to generate an overall three-dimensional model of the crane; performing optimization calculation on the crane model, and performing calculation according to the parameter data to obtain stress data of the crane model; and performing determination by using the calculated stress data, and determining whether the crane model meets a use standard or not. The present invention can avoid the possibility of occurrence of damage and collapse which is caused, by a model design problem in a model design stage.
