Due to the characteristics of light weight and high strength

weakly-rigid thin-walled workpieces are widely used in aerospace

automobile and other industrial fields

but they also have the disadvantages of small thickness

low rigidity and easily deformation during the manufacturing process. The fixture layout design is a very important factor to reduce the deformation and ensure the quality of thin-walled workpieces. Traditional fixture layout design of thinwalled workpieces depends on the intuitive judgment and experience accumulation of engineers

which is slow

high cost and large randomness of design. With the continuous improvement of computer technology

many scholars applied finite element simulation

mathematical programming method

intelligent optimization algorithm

surrogate model and so on to optimize the layout of thin-walled workpieces fixture components

and have obtained a lot of research results. According to the modeling method of objective function and the optimization algorithm

the related researches are systematically classified and discussed

and the merit and demerit of each modeling method and optimization algorithm are analyzed in detail. Finally

the related researches on the fixture layout optimization method of weakly-rigid thin-walled workpieces are summarized

and the corresponding research advice are put forward.
