Abstract: Aiming at analysis of spreader block of STS, the static and modal analysis of typical operating conditions was carried out with software Hyperworks, in which the finite element model was built and mass, force and constraints were simulated through multi point constraint model. First, the stress and displacement nephograms were obtained through optistruct based on operating conditions and FEM. Second, the influence of different operating conditions on the structure was compared and analyzed. Last, the natural frequencies and modal shapes of the first six orders were analyzed and the influence of different modal shapes on the spreader block was obtained. The results indicate that the structure meets the static requirement and has good dynamic characteristics. A practical means for structural design and optimization of spreader can be got through the research.

Key words: spreader block; Hyperworks; static and modal analysis
