Abstract
To take ZLP500L type suspended platform for research object, establishes parametric finite element model with ANSYS, and analyze static performance of its structure. Define the platform section parameters as the design variables, and structure in dangerous working conditions of stress and displacement as state variables, makes optimization design of platform with first-order method, so obtain lightweight high degree of section parameters which reducing 26.16% total quality of platform. Meanwhile makes buckling analysis of optimized platform to obtain smallest the critical load coefficient is 171.56, and then verifies the platform structure stability, provides theory basis to ZLP500L type suspended platform design and alteration.
