Clothes tree modal performance design method based on morphology optimization

Abstract

The invention relates to a clothes tree modal performance design method based on morphology optimization, and the method comprises the following steps: 1, calculating a clothes tree constraint modal result: obtaining the size of a clothes tree first-order modal, and knowing the difference between the clothes tree first-order modal and a target; 2, performing morphology optimization analysis: calculating a distribution result of the reinforcing ribs according to parameter setting of a morphology optimization analysis model; and 3, verifying an optimization scheme: designing a reinforcing rib scheme convenient to manufacture according to the reinforcing rib distribution in the previous step, carrying out modeling calculation on the scheme, verifying whether a result of the scheme meets a target or not, and if the result of the scheme cannot meet the target, continuing to optimize until the result reaches the standard. According to the method, the efficiency problem is solved, the structure is modified repeatedly according to experience, the target requirement can be met within limited time, and modal performance design becomes easier to achieve.

Description

technical field [0001] The invention belongs to the technical field of modal performance design methods, in particular to the technical field of a shape optimization-based modal performance design method for a coat rack. Background technique [0002] The general design process for the design of thin-plate parts in the prior art is as follows. First, make a preliminary design, and make the overlapping edges with the surrounding parts, and then arrange some ribs in the middle where ribs can be formed according to experience, and then perform CAE simulation. Analyze and verify whether its modal and stiffness properties meet the target, and if the target is met, the design is completed, otherwise, continue to modify until it reaches the target. Problems existing in the existing technology: The problem existing in the existing technology is that when the ribs are initially arranged, the designer does not know how to arrange them better, so they can only rely on experience and pos...

AI Technical Summary

Problems solved by technology

Problems existing in the existing technology: The problem existing in the existing technology is that when the ribs are initially arranged, the designer does not know how to arrange them better, so they can only rely on experience and postpone the CAE simulation verification, which does not meet the goal. Then modify the structure until the goal is met, the whole process cycle is longer and the efficiency is lower
