Abstract: Aiming at the structural strength and rigidity of the large complex paver frame are difficult to guarantee in the design process, which caused the paver frame to deform and crack in the construction process, in order to improve the construction effect and reliability of the paver, the structure analysis of the paver frame based on the finite element method was carried out. According to the various conditions of the paver, the static and modal of the paver frame was analyzed with finite element analysis method, then the frame stress and strain contours, natural frequencies and mode shapes was obtained, which provided the basis for structure optimization. At the same time, the improvement method of the frame structure stiffness was proposed, which was aimed at the weak link of the frame structure to increase ribs at front and rear plates and the beam crosssectional dimensions of left and right side. The results indicate that the strength analysis and check of the structure in advance in the early stage of design can avoid some design defects and deficiencies from the source, provide theoretical basis for the design and research of the prototype, and have practical significance for improving the working efficiency and stability of the paver.
