Abstract:The problem of structural analysis and optimization of aircraft electro-hydrostatic actuator (EHA) action cylinder is researched in this paper. Using ANSYS finite element analysis software, load, modal shape and compression stability of EHA action cylinder are discussed respectively. Taking the minimum mass and minimum deformation of action cylinder as objective function, while meeting the constraints of stress and modal, the optimization model is created using ISIGHT software. NLPQL sequential quadratic programming algorithm, which is embedded in ISIGHT, is used to get optimization results. Final analysis conclusion suggest that using ISIGHT software to optimize and design product can easily get the result and reduce the workload, meanwhile the designed action cylinder parameters are more reasonable.
