Method for designing a heavy machine tool composite foundation with a non-uniform reinforcement layer

Abstract

The invention discloses a method for designing a heavy machine tool composite foundation with a non-uniform reinforcement layer, which is used for redesigning a traditional machine tool foundation structure, avoiding the defect of high cost increase caused by excessive rigidity of a bottom structure of a traditional foundation, and ensuring the bearing capacity of the foundation. According to themethod, the displacement components of all points in the foundation are solved, and pouring construction of the composite foundation is achieved. The heavy numerical control machine tool system is divided into three parts, namely an upper structure, a foundation and a foundation. Cost generated by excavation and pouring of the foundation is even higher than the price of a machine tool, so that thestructural design of the foundation needs to be researched, and the expenditure is reduced as much as possible under the condition that the rigidity of the foundation meets the machining requirementof the machine tool. By the adoption of the bottom sparse arrangement reinforcement layer mode, on one hand, the bearing capacity of concrete on a machine tool during machining is guaranteed, and on the other hand, the construction expenditure of a machine tool foundation is reduced by reducing the bottom reinforcement layer.

Description

technical field [0001] This patent relates to the field of heavy machine tool-foundation design and construction, especially for the field of foundation structure design and research, and can also be applied to the field of small experimental equipment. Background technique [0002] In recent years, with the implementation of a number of key special programs by the State Council, the government has continued to increase capital and manpower investment in key projects such as aerospace, nuclear power and wind power, railway locomotives, ships and ships, and transportation. The key components of engineering equipment are all large-scale, heavy-tonnage, and high-precision workpieces. To undertake the processing of such typical components, it is necessary to develop high-level large-scale, heavy-duty, and super-heavy CNC machine tools. The heavy CNC machine tool system is divided into three parts, such as figure 1 As shown, namely the upper structure (gantry machine tool 1), fo...
