In view of the huge domestic air cargo market and the improvement of domestic equipment support capability for aviation emergency rescue, this paper proposes a lifting platform that serves airports and can realize multiple purposes. On the basis of structural design, the lifting part is taken as the main research object for optimal design, and the scissor lifting structure driven symmetrically is taken as its lifting mechanism. The parametric model of the scissor lifting frame is established by using virtual prototype technology. The optimization target is determined as the minimum/maximum thrust of the oil cylinder, and the optimization object is the position of the main hinge point. After optimization, the maximum thrust of the oil cylinder is reduced by 28.4%, and the fluctuation range of the radial velocity of the oil cylinder is obviously reduced compared with that before optimization. Using the finite element analysis software ANSYS, the strength of the main stressed components at the most dangerous moment is checked. The analysis shows that the components are reasonable in structure, safe and reliable, which can provide theoretical support for the production of real objects.
