Embodiment Construction
[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the present invention includes but is not limited to the following embodiments.
[0019] In the process of actual engineering structure design, the influence of disturbances such as the magnitude, direction and action position of the external load on the design of the force transmission path of the structure is fully considered, and the resistance of the structural performance to the uncertainty factors of external loads is improved, so that it can withstand the complex stress environment. It is a problem that must be considered in the structural optimization design to be able to perform the expected function normally and stably. The invention provides a structure topology optimization method which can consider the uncertainty of the direction of the external load, optimizes the topology configuration of the structure based on the absolute value of the m...
