Abstract

Taking the turntable of the crane as the object, it simulates the equivalent forms of process reinforcing in the large floor of the turntable. And it obtains welding deformation. By simulating the equivalent forms of process reinforcing, it discusses the influence on welding deformation by rigid fixed, contact, the unidirectional deformation constraint and adhesive contact. It verifies the results by experiments. The results show that they design four groups of the equivalent models, and calculate the welding deformation results of the large floor. When process reinforcing is equivalent to rigid fixed and contact, it predicts the deformation greatly. When process reinforcing is equivalent to the unidirectional deformation constraint and adhesive contact, it predicts deformation relatively small. By adhesive contact, deformation distribution is consistent with measured results, and error is within 6%. It verifies equivalent method is practical in the finite element analysis.
