Description

technical field [0001] The invention relates to the fields of engineering mechanics and electronic technology, in particular to using electronic equipment as an auxiliary tool to complete the calculation of stress required in engineering. Background technique [0002] In various engineering practices, although the types and uses of components are different, when the structure works normally, each component is subject to external forces transmitted from adjacent components or other objects. In order to ensure the normal operation of components, three requirements generally need to be met. [0003] First of all, the components have sufficient strength, and the components must not break under a certain external force. For example, when lifting heavy objects, the steel wire rope should not be broken by the heavy objects. Secondly, some components, such as the machine tool spindle, have excessive permanent deformation after being stressed, and the deformation of the machine cann...
