Topology Optimization Of Large-Scale Hydraulic Radial Steel Strobe

Optimal design has occupied an important position in the modern design of the structure, it can project from the large number of programmers in a more perfect or suitable optimal design,it is a virtual design and manufacturing of important links, and throughout the development and production Process. Topology optimization is the most challenging way of optimal design in the areas of research, is still improving and developing.In this paper, based on finite element analysis and structural topology optimization theory, by using ANSYS, optimized radial steel strobe by two-dimensional and three-dimensional, and got the reasonable layout of the range of parameters of radial steel strobe through the different aspect ratio and the arc radius of the door Three-Dimensional Topology optimization, finally, optimized an example by contrasting with the topology optimization results, improved layout of its strength remain the same or be enhanced on the basis of stiffness has been strengthened. Summed up the whole process of analysis, mainly got the following results:(1)Topology optimization the radial steel strobe on a two-dimensional by ANSYS, in the process of optimization radial steel strobe which was divide up into of vertical framework and horizontal framework. In the horizontal frame work of the mainly on the main cantilever beams of the optimal topology parameters, given the different radial steel strobe than the width of the door with a radius of the main cantilever beams optimal topology parameters. Within the frame work of the vertical, from top to bottom Longitudinal Beam mainly on the cantilever, and the middle of the optimal parameters of topology, combined with a large number of numerical analysis presented in the framework of different vertical gate doors radius and a high degree arc of circumstances than the optimal topology layout Parameters.(2) Compared to two-dimensional topology gate space structure does not reflect the shortcomings of the form of topology, the paper curved steel gate on a system of three-dimensional topology optimization, be reasonable-gate space of the path. In this paper, three-dimensional topology optimization process completed in two stages, initially selected as possible optimize the design domain, including the possibilities to ensure that the structure, optimize the secondary is in the initial optimization on the basis of preliminary results of optimizing the equivalent treatment Optimize the design as a secondary domain, the results show that this approach is applicable. Lastly, the door is a different aspect ratio and radial steel strobe of the door under the conditions of the gate layout of the three-dimensional topology optimization parameters and limits of structural form of choice.(3)Use of the powerful finite element analysis software ANSYS, a curved steel gate finite element model and an example of the design structure of the static and dynamic analysis. By calculating the initial master arc steel gate of the stress and deformation, an analysis of the condition of the four gates in the natural frequency and vibration mode. These parameters used to evaluate the final results of the optimization of reference.(4)Improved layout and optimize the layout of a radial steel strobe based on the results of three-dimensional topology optimization, and done the static and dynamic finite element analysis. By comparing the static and dynamic features of the structure before and after the optimization, proved the superiority of the optimized structure. Meanwhile, showed the topology optimization is of applicability in the radial steel strobe design.
