Hydraulic tipping platform is an effective scattered materials automatic unloading devicefor vehicle or container, it can be widely used in grain depot, port, mining, chemical, food andother company which need automatic unloading scattered Materials, especially in the processof grain scattered unloading plays an important role in our country. In the hydraulic tippingplatform working process, vehicle or container is fixed on the tipping platform, and by thelifting bracket that connected the hydraulic cylinder completed unloading process.By investigated to the existing hydraulic tipping platform in design level, found that thecurrent Structure and design method of hydraulic tipping platform is very dated, it mainlydesign method is imitates other automatic unloading device structure, and through thetraditional mechanics method and experience to design. Although this method can ensurehydraulic flap structure strength and stiffness, this design method is very conservative, leadingto the waste of material and large weigh, severely restrict the hydraulic tipping platform seriesdevelopment. However, the finite element method can have a more accurate analysis forhydraulic tipping platform structure, so that making the hydraulic tipping platform’ designmethod from experience design into science design phase.Tipping platform and the lifting bracket are mainly bearing and the lifting component, isthe core part of hydraulic flap. This study combined with engineering examples, afterintroduced the finite element method’ the basic idea、theory and method, use inventor softwareto establish the solid model of the tipping platform and lifting bracket, using the finite elementpre-processing software HyperMesh to tipping platform and lifting bracket made grid division,and import it into Ansys software to calculate analysis. Draw the equivalent images of thetipping platform and lifting bracket under various stresses and deformations, from it we cansee that the stress change trend and dangerous position of structure in the work process, whichhas an important guiding significance to hydraulic tipping platform structure optimizationdesign.All analysis results show, the current hydraulic tipping platform and lifting bracket strength and stiffness have a large surplus, having lightweight space. In this paper, on the basisof not changing the hydraulic tipping platform’ manufacture technology, put forward specificoptimization scheme, and made strength checking for improved model, ensure the tippingplatform and lifting bracket can meet the design requirements, realized the aim of structureoptimization.Through this study, reduced the hydraulic tipping platform structure weight, improvedthe hydraulic tipping platform manufacturing process, and achieved good economic and socialbenefits; On the other hand，that reserved valuable hydraulic tipping platform numericalmodel and relevant technical data for enterprise, which has certain guidance meaning for theactual hydraulic tipping platform structure improvement. At the same time, this paper used thefinite element method made structure analysis to hydraulic tipping platform, this is valuableboth in academic research and practical application.
