Aiming at the problem of low strength and low rigidity of the support plate of the large-scale split jack multifunctional rescue attachment, a simulation model of the attachment is established based on the working principle of the split jack rescue attachment. The limit working condition is used as the input condition, and the finite element analysis is carried out on the support plate of the split jack rescue attachment. Based on the response surface method and multi - objective genetic algorithm, the main size parameters of the support plate are selected as the design parameters, and the maximum equivalent stress, maximum deformation and mass minimization are the optimization goals, and the optimization model of the support plate is established. Optimize its structure. The result shows that the strength and rigidity of the support plate are improved without increasing the mass.
