Owing to the excessive time cost of finite element simulation calculation for thin-walled parts fixture locating layout design

a optimization design method for thin-walled parts fixture positioning based on Kriging surrogate model and flower pollination algorithm (FPA) is proposed. With a given number

the fixture locating layout is treated as the design variable

while the strain energy of thin-walled parts under self-weight as the optimization target. Firstly

the optimal Latin hypercube sampling and finite element analysis are used to generate training samples. Secondly

the training sample is used to construct the fixture positioning optimization agent based on Kriging surrogate model. And thirdly

FPA is applied to search the optimal solution for thin-walled parts fixture locating layout. Finally

the optimization design of the curve thin-walled parts fixture layout under “4–2–1” locating principle is taken as an example to verify the effectiveness of the proposed method.
