Embodiment Construction
[0037] The application will be described in further detail below in conjunction with the accompanying drawings.
[0038] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0039] First, the nouns involved in the embodiments of the present application are introduced.
[0040] The turning lug is mainly used to turn over the wind power gearbox during the assembly process to assist in the completion of various assembly tasks of the wind power gearbox. Therefore, whether its strength meets the standard is one of the important factors for the smooth progress of the entire assembly process.

This application relates to a method for checking the strength of the lifting lugs of a wind power gearbox, which includes: Step 1, establishing a geometric model of the gearbox shell in the drawing software; Step 2, importing the geometric model of the gearbox shell into the finite element software , to establish a finite element model; Step 3, define the element types of each component of the gearbox shell in the finite element software, and use solid elements; Step 4, define the material properties of each component of the gearbox shell; Step 5, the gear box shell load on the finite element model of the body; step six, apply boundary conditions to the finite element model of the gearbox casing; step seven, submit the finite element model of the gearbox casing to the finite element software for solution, and extract the maximum The stress and strain of the turning lug are compared with the allowable stress and allowable strain of the turning lug material to obtain the comparison results for checking whether the strength of the turning lug of the wind power gearbox meets the requirements. The present application has the advantage of being convenient for improving the accuracy of checking the strength of the turning lug.
Description
technical field [0001] The present application relates to the field of strength detection of turning lugs of wind power gearboxes, in particular to a method for checking the strength of turning lugs of wind power gearboxes. Background technique [0002] In recent years, the wind power industry has developed rapidly, and the weight of the wind power gearbox has become heavier and heavier. The strength of the turning lugs has also become an item that must be checked. Among them, the turning lugs are mainly used to turn over the gearbox during the assembly process, so as to assist in the completion of various assembly tasks. If the strength of the turning lugs does not meet the requirements, it may affect the assembly work, and even cause safety problems during installation. Therefore, the strength check of the turning lug becomes particularly important. [0003] In the relevant wind power gearbox turn-over lug strength check scheme, the product quality check is generally only...
