【Abstract】 In order to further explore the most unfavorable position of the platform and find the minimum area to withstand the load.Solidworks 3D software was used to model the scissor lift platform, and the load-bearing area was segmented and parameterized. It was jointly imported into finite element software for static analysis. The total deformation and maximum stress at four extreme positions were calculated,and it was verified that the maximum stress of the scissor lift platform was less than the allowable stress of the material. Subsequently, the response surface method was used to optimize the extreme positions. The Latin hypercube experiment was used to construct the sample space. By calculating each sample point, the finite element response value was established, and the fitting quality of the response surface was verified through evaluation indicators. While meeting the stability of the system structure, the minimum load-bearing area during the use of the platform was found, and the strength and stiffness of the position met the design requirements. Provide reference for the safe use of the scissor lift platform in the future.更多还原
