Abstract

The invention discloses a quantitative method based on engineering machinery structural design. The quantitative method includes the following steps that an engineering machinery structural member parameterization integrating design system is used for fast generating an engineering machinery structural member model; the engineering machinery structural member model on which a statics analytical method is conducted is simplified; finite element analysis is then conducted; an Ansys topological optimization module is combined, a homogenization method for topological optimization is used for conducting optimization analysis on a structural member of the engineering machinery structural member model, size optimization and shape optimization are conducted on the basis of an obtained result, the engineering machinery structural member parameterization integrating design system is used again for generating a design model, the obtained design model is checked, and if it is checked that the design model does not meet the design requirement, the size optimization design and the shape optimization design are conducted again until the design model meets the design requirement. The purposes of saving steel, reducing cost and improving operation stability and safety are achieved.

Description

technical field [0001] The invention relates to the field of mechanical design, in particular to a lightweight method based on structural design of engineering machinery. Background technique [0002] In recent years, with the rapid development of the construction machinery industry, lightweight will become one of the main development technology directions of the industry. Lightweight construction machinery, especially the research and application of construction machinery structure is of great significance to promote the rapid development of construction machinery, which can effectively reduce the quality of equipment, improve product performance, and save resources and energy. It has a direct impact on reducing energy consumption, exhaust gas emissions and noise reduction in the process of operation, and has huge potential for energy saving and consumption reduction. [0003] Construction machinery structural parts refer to steel plate welded structural parts; for example...
