Abstract: Provided is a structural topology optimization method based on material-field reduction series expansion; the invention solves the problem of conventional density method topology optimization wherein computational efficiency is low because of excessive design variables, relative density requirements, or sensitivity filtering measures. By means of defining a bounded material field which takes relevance into account, a spectral decomposition method is used for transformation into a series of linear combinations of undetermined coefficients, and, taking those undetermined coefficients to be design variables, an optimization model is constructed on the basis of a cell density interpolation model; a gradient or non-gradient optimization algorithm is used to solve the topology optimization problem, and thus a topological configuration having clear boundaries is obtained efficiently. The method greatly reduces the number of design variables in density-based topology optimization, and also has the natural advantage of completely avoiding mesh dependency and checkerboard pattern problems. The method also inherits the advantages of the density method, such as its simple form and convenience in promotion in engineering, has a rapid speed of optimization solution, and ensures efficiency in the research and development of innovative topological designs of complex equipment structures.

Abstract: The present invention relates to the technical field of construction, and relates to a double steel plate composite shear wall that has an external pressure-bearing and untensioned concrete embedded damping interlayer. The present invention successively comprises from the inside to the outside: a concrete core layer, a steel plate layer, a damping interlayer, and an outer concrete layer. Two sides of the steel plate layer are each connected to a concrete-filled steel tube bundle, and a concrete core is poured between the steel plate layer and the concrete-filled steel tube bundles. The double steel plate composite shear wall that has the external pressure-bearing and untensioned concrete embedded damping interlayer further comprises a top plate and a bottom plate which are connected to top and bottom parts of a wall respectively. In the present invention, the outer concrete layer is not directly connected to the concrete-filled steel tube bundles at the two sides, and there are small cross-sectional areas at the top and bottom parts, so that the outer concrete layer does not directly bear horizontal loads, and will not generate deformations or else generates relatively small horizontal tensile and compressive deformations; and thus, the outer concrete layer only bears vertical loads, which greatly improves the vertical bearing capacity and seismic performance of the wall.

An Fe-B iron-boron alloy can be recycled to produce a neodymium-iron-boron permanent magnetic material after being refined; and metals such as Bi and Nd in the bismuth rare earth alloy are separated by means of vacuum evaporation. Under environmentally-friendly conditions, rare earth elements such as neodymium in neodymium-iron-boron are separated in one step, and the recycling of iron and boron elements is realized.
